Introductory Chapter: Updates in
Volcanology - Transdisciplinary
Nature of Volcano Science
KárolyNémeth
. Introduction
Transdisciplinary approach of science appeared in recent years, partially
as a result of the urgent need to deal with global and planetary changes [1–12].
Transdisciplinary science is to answer and solve environmental science questions
and problems became the foundation of sustainable development, nature conserva-
tion and various environmental science education including geoeducation [1317].
Transdisciplinary approach within volcanology was always a key element of
volcano science as volcanology addresses key questions over volcanic hazards, risk
and resilience naturally moving along the interface of social science, humanities,
natural science and non-academic (e.g. indigenous) knowledge [1825]. Especially
in recent years more and more researches were conducted on subjects to help to
understand the interface between western science and traditional knowledge
[2630]. Such works explored various aspects of volcanism that affected the human
societies greatly both as processes that produce natural resources for development
and in other hand continuous fear that need to be dealt with to prevent societies
from their destructive powers [28, 3134]. The transdisciplinary aspects of volca-
nology is reflected well in the new volcano model and volcano geology approach
to understand volcanic systems and placing them in a geosystem perspective [35]
(Figure ). In many volcano research aimed in recent years to develop some sort of
volcano model that explain the volcanic processes, their resulting eruptive prod-
ucts, and the way such models can help to develop a better strategy for resilience
against volcanic hazard within a general natural hazard framework [4043].
. From volcano geology to volcano model development
The various volcano models distinguish between type of volcanoes commonly
categorized monogenetic versus polygenetic volcanoes (and volcanism) as a
reflection of the total eruptive volume, the total duration of volcanic activity, the
strength of the link to the magma generation source and the stability and longevity
of a volcanic conduit [44, 45]. In these models obviously the end-member types
of volcanoes define short, small, simple (versus long-lasting, large and complex.
Recent decade of research in addition, provided ample evidences that the scale of
observation (hence the detail of information could be mined from volcanic systems)
is important, and provides evidences to support that in real world end member type
of monogenetic volcanoes are rare, and most of them shows some sort of complexity
in a near continuous spectrum [20, 4652]. This is more apparent when the magma
that form those volcanic geoforms are more evolved [53, 54]. In recent years attention
Updates in Volcanology – Transdisciplinary Nature of Volcano Science
also turned toward effusive style of volcanism that is not obviously can fit into any of
these categories. The current eruption of Iceland’s Reykjanes Peninsula that started
on the 19th March 2021 8.45PM (Local Time) provided and exceptional occasion to
observe how a volcano start its life (Figure A and B). Commonly, the first moments
of a volcano growth is missed by direct observation and later on the initial eruptive
products become covered by subsequent eruptive products, missing key elements of
the early, very critical phase of the eruption [55]. The new eruption in Iceland, that
gradually building the new volcano Geldingadalir operating along an approximately
800-meter long fissure and at least 6 distinct vent zones (Figure A and B). The
opportunity to observe the vent localization process commonly based on a combina-
tion of direct observation and study older volcanic successions [56, 57] is valuable
to understand fissure-fed eruptions. Such geological observations and records can
provide a dynamic view on fissure-fed eruptions in basaltic systems and help to inter-
pret the resulting eruptive products (Figure C and D). In this respect the interlink
between observation-based volcanology can be linked to various geoeducation works
that provide good, evidence-based information to understand the volcanic geoher-
itage [58]. In case of the growth of the Geldingadalir volcano, it provides insight on
the formation of steep spatter cones documented from the geological records else-
where, for instance during the 1256 Al Madinah eruption in Saudi Arabia [59].
Numerous research work has been completed with a prospect to provide vol-
canic hazard maps [6065] as well as some sort of tools to communicate to com-
munities volcanic hazards [66], co-design, co-product programs and products to
help developing a more resilience community that can live with the volcanoes and
their hazards [28, 67–78]. In recent years, there is also a strong movement visible
Figure 1.
Complex volcanic landscape in northern Chile is a fine example to demonstrate the volcano geology approach
to interpret the present day geoforms. The landscape is ruled by the basaltic-andesite to dacite lava dome-
dominated Ollagüe (5868m asl) stratovolcano, which stands 1686 meters above the surrounding Salar de
Carcote desert floor. The volcano has an active hydrothermal system in its top (note the white cloud in the
right edge of the summit), while the volcano itself had its last eruption about 65ka [36, 37]. In the side of the
volcanic edifice satellite domes formed such as the El Ingenio lava dome in the NW (left in the image) side of
the cone [38]. In the foreground a typical hummocky surface of volcanic debris avalanche that generated by a
sector collapse can be seen that formed in the late-Pleistocene. The image was taken from a small scoria cone
La Poruñita, that is part of a monogenetic volcanic field nearby and formed after the sector collapse of the
stratovolcano [39]. This complex geological setting of this volcanic system highlights the importance to study
volcanoes from volcano geology perspective.

to conduct research jointly with other experts in archaeology for instance to better
understand the impact of volcanism on early civilizations [7993].
. Volcanic geoheritage
Moreover in the last decades a boom of research is visible where volcanic geo-
heritage used and utilized as a main opportunity to develop geoeducation programs
accompanied with effective geoconservation programs (commonly formed as a result
of citizen science, and co-design) to build a more resilience society against volcanic
hazard [94104]. Even new terms appeared such as social volcanology or paleo-social
volcanology steamed from social geology to express the newly and rapidly evolving
discipline formed recently [72, 105]. Most of this works based on a more precise and
process-oriented understanding of volcanic systems such as monogenetic volcanoes.
The dynamic progression on volcanic geoheritage, geodiversity and geotourism
research made a new aspect of volcano science where interface between natural
sciences, humanities and social sciences meet and put into practical sense making
volcanology a more relevant science to human society and our natural environment
Figure 2.
Lessons from the current volcanic eruption of the Geldingadalir volcano in Iceland can be used to better
understand of the first moments and processes of a volcano growth in basaltic systems (A, B). Flow localization
formed vents that emitted lava and spatter creating steep spatter cones (A) through mild explosive event
(B). To see this process in real can help to interpret similar volcanic successions elsewhere such as those formed
during the 1256 Al Madinah eruption in Saudi Arabia (C) or during the Pleistocene and Holocene in the
Harrat Khaybar, also in Saudi Arabia (D). The solidified inner structure of a spatter cone shows well the steep
pile of spatters accumulated around the vent (D) similar how such process take place right now in Iceland
(B). Photos of A and B are from the photo collection of Viktória Komjáti.
Updates in Volcanology – Transdisciplinary Nature of Volcano Science
[103, 106]. In addition, an increased recognition of traditional knowledge and cul-
tural aspects of volcanoes explored and made mainstream research outputs [107111].
. New advances in volcanology as a transdisciplinary science
Looking into detail of the recent evolution of volcano science we analyzed the
accessible, mainstream literature data stored in the Thomson Reuters, Web of
Sciences Core Database. Volcanology has two premier publication avenue such
as Bulletin of Volcanology (Springer) [BV] that is also the official journal of the
International Association of Volcanology and Chemistry of the Earths Interior. In
addition, Journal of Volcanology and Geothermal Research (Elsevier) (JVGR) also
considered as a main medium for scientific communication within volcanology.
We were curious to see what research trend can be deducted from the published
researches in the last 2years (2019 to 2021, 20 April 2021) within these two pre-
mier Journals. We used search operators to identify keywords (including Author
keywords and Web of Science generated keyword set). We understand that these
keywords commonly reflecting general “umbrella subjects” and not obviously the
main subject of the specific published papers, but we still think they are representa-
tive and informative to identify trends. For this, we created word clouds by using
the WordArt online tool [https://wordart.com/] to visualize main keywords (larger
words in more central position reflects more common appearance of such key-
words). For the Bulletin of Volcanology 184 paper was identified. From these 184
papers keywords were extracted, while common non-informative words deleted as
well as too generic words such as volcanism, volcano, volcanic, eruption, magma, lava
pyroclastic and based. In addition, manually all the location keywords were deducted
and inserted to a separate file to see the common locations research focused in the
past 2years. Following this method, the Flow, Ash, Dome Size, Current words
stand out reflecting the research output intensity around tephra and various
geophysical flow research (Figure A). The rest of the keywords show a fairly even
distribution across the entire spectrum of subjects. Applying the similar techniques
to the JVGR, on the basis of 557 papers published in the same period of time showed
keywords as most common to be System, Flow, Evolution, Model, Isotope,
Hydrothermal, Fluid (Figure B). To look at the common locations current volca-
nology research associated with published within BV showed Bogoslof, Kilauea,
Figure 3.
Keywords identified on Web of Science Core Database papers published since 2019 in the two major volcanology
scientific magazines, Bulletin of Volcanology (A) and Journal of Volcanology and Geothermal Research (B).

Puna, Andes and Etna as top for BV (Figure A), while Andes, StHelens, Etna,
and Iceland having the most common location keywords for JVGR (Figure B).
The following method was applied for a narrower time frame (last months)
but looking at the title, keywords and abstract of the published papers in the two
major volcanology magazines (Figure ). From the 101 published papers the Erupt,
Volcan, Volcano, Lava, Magma words were the most commonly used while in the
“second” abundance more process-related words such as Flow, Deposit, Data,
Model, Explosion, System, Observe etc. appeared.
As volcanic geoheritage became an important aspect of volcano science recently
we checked the main keywords associated with researches identified under volcanic
geoheritage topic search term from the Web of Sciences Core Databases. A total of

Updates in Volcanology – Transdisciplinary Nature of Volcano Science
79 paper has been identified in the time period between 2010 and 2021, suggest-
ing the very recent formulation of this term (Figure A). To see this results in a
perspective we made a keyword search for Geoheritage that resulted a total of 530
published papers between 2011 and 2021 (only 10years!!). By removing the most
non-generic terms such as Heritage, Geotour, Geoheritage, Geoconservation,
Geosite and Geopark, focusing on those keywords that were identified between
10 and 100 occasions we can see that Volcanic is a common keyword within
geoheritage studies (Figure B). This suggests that volcano science gradually build
a strong corner within geoheritage, geoconservation and geoeducation. For curios-
ity we made a survey to check the published papers by searching Volcanic AND
Transdisciplinary that resulted 8 published papers between 2015 and 2021 indicat-
ing the recent identification of this technical terms.
In summary we can say that volcano science is a very colorful and fast evolv-
ing science. Its transdisciplinary nature is getting more and more recognized and
applied for a very diverse array of research areas and practical approaches to com-
munity engagement. This book offers another snapshot to this process.

that were too general to see the details of research outputs hence keyword resulted 10 to 100 scores were plotted

... Monogenetic volcanism represents the most common type of volcanism on Earth (Walker, 2000), generating small-volume volcanoes (<1 km 3 ) with lifespans of the order of days to decades (Wood, 1980;Németh and Kereszturi, 2015). A clear and exceptional example of this corresponds to the current eruption of the Geldingadalir volcano in Iceland's Reykjanes Peninsula, which started on 19 March 2021 and formed a small shield volcano, featuring a spatter cone and associated lava flows (Németh, 2021). This type of volcanism produces a wide range of eruptive products and volcanic edifices, which may or may not form volcanic fields (Németh, 2010;Martí et al., 2016). ...

The Negros de Aras monogenetic volcanic field in the Central Volcanic Zone of the Andes displays the highest concentration of scoria cones in northern Chile (0.23 per km²). It contains 66 vents, 22 of which are emission points of lava flows without an associated recognizable volcanic edifice, whereas 44 are typical scoria cones. Most vents are associated with basaltic andesite and andesite lava flows of up to 4.6 km in length. A few scoria cones show signs of either initial or final phreatomagmatic eruptions recorded in their pyroclastic successions. A geomorphological, morphometric, and spatial distribution analysis of the scoria cones of this volcanic field was carried out with the purpose of identifying the factors and processes that governed their emplacement, growth, and final morphology. The morphometric analysis was performed on 16 well-delimited scoria cones applying the MORVOLC algorithm using the TanDEM-X 12 m resolution digital elevation model. Analysis of the distribution and elongation of the craters of the scoria cones defines four alignments inferred to be related to the local and regional structural elements of the area. Volcanic activity seems to have been related to a N-S fault system with an E-W maximum stress orientation, favoring magma ascent and scoria cone emplacement following inherited fractures in these preferential orientations. The scoria cones show a wide range of morphologies and morphometries that can be related to different syn- and post-eruptive processes. Cones with large craters and high crater width / basal width ratios show clear evidence of phreatomagmatic eruptions (within their pyroclastic successions), whereas horseshoe-type cones are related to cone breaching or coeval lava flow effusion, and more pristine (i.e., relatively younger) cones are generally steeper.
... These factors can be determined by direct measurements of active lava flows, such as temperature, eruption duration, or effusion rate (e.g., Pinkerton, 1993;Harris et al., 2007). An example of direct measurements is the monitoring of the current eruption at Geldingadalir volcano in Iceland (Németh, 2021). In solidified lava flows, estimations of flow dynamics can be obtained considering parameters measured in previous eruptions (Pinkerton and Sparks, 1978;Park and Iversen, 1984), in historical descriptions (e.g., the 1256 CE Al-Madinah eruption (Saudi Arabia); Camp et al., 1987;Harris et al., 2000 and references therein;El-Masry et al., 2013;the 1980-1999 Mount Etna eruption (Italy)), or through the analysis of the lava geomorphology or morphotypes (e.g., Duraiswami et al., 2008;Murcia et al., 2014), modeling of the pre-eruptive surface (e.g., Kereszturi et al., 2014Kereszturi et al., , 2016, calculation of initial viscosity of the lava flow (e.g., Giordano et al., 2008;Herzberg and Asimow, 2015), and rheological models (e.g., FLOWGO; Harris and Rowland, 2001;Mossoux et al., 2016). ...

Effusion rate is the instantaneous lava flow output by a vent. It is one of the most important factors that govern the emplacement and dynamics of lava flows and can be determined by direct measurements or estimated through modeling. The Negros de Aras monogenetic volcanic field, located in the Central Volcanic Zone of the Andes, is the largest volcanic field in northern Chile. It is situated north of the active Socompa volcano and south of the Salar de Atacama basin, consisting of scoria cones and lava flows. Here, we estimate the effusion rates of three overlapping and representative solidified lava flows from this volcanic field applying an iterative procedure using the Q-LavHA GIS plugin, where the effusion rate is treated as an unknown parameter and the solution is reached by comparing the simulated results with the real extension of the flows. The pre-eruptive surface was reconstructed using the 12 m resolution TanDEM-X digital elevation model. Other required input parameters for the modeling (e.g., channel ratio, viscosity, temperature) were estimated through geomorphometric, petrographic, and geochemical analysis. The estimated effusion rates vary between 14 and 113 m³/s, comparable with rates measured elsewhere. The method was validated by applying it to two directly measured (Nyamuragira 2006; Mount Etna 2001) and one calculated effusion rate (Lentiscal 2450 BP, Canary Islands). The estimated effusion rates gave an average underestimation of 10%. Considering this percentage of adjustment, the effusion rates for the three studied lava flows from the Negros de Aras monogenetic volcanic field vary from 15 m³/s to 124 m³/s. Our results provide valuable information for mitigating volcanic risk in the event of future lava flow eruptions, which could affect nearby villages and mining operations.

Satellite imagery provides a rich source of information that serves as a comprehensive and synoptic tool for the continuous monitoring of active volcanoes, including those in remote and inaccessible areas. The huge influx of such data requires the development of automated systems for efficient processing and interpretation. Early warning systems, designed to process satellite imagery to identify signs of impending eruptions and monitor eruptive activity in near real-time, are essential for hazard assessment and risk mitigation. Here, we propose a machine learning approach for the automatic classification of pixels in SEVIRI images to detect and characterize the eruptive activity of a volcano. In particular, we exploit a semi-supervised GAN (SGAN) model that retrieves the presence of thermal anomalies, volcanic ash plumes, and meteorological clouds in each SEVIRI pixel, allowing time series plots to be obtained showing the evolution of volcanic activity. The SGAN model was trained and tested using the huge amount of data available on Mount Etna (Italy). Then, it was applied to other volcanoes, specifically, Stromboli (Italy), Tajogaite (Spain), and Nyiragongo (Democratic Republic of the Congo), to assess the model’s ability to generalize. The validation of the model was performed through a visual comparison between the classification results and the corresponding SEVIRI images. Moreover, we evaluate the model performance by calculating three different metrics, namely the precision (correctness of positive predictions), the recall (ability to find all the positive instances), and the F1-score (general model’s accuracy), finding an average accuracy of 0.9. Our approach can be extended to other geostationary satellite data and applied worldwide to characterize volcanic activity, allowing the monitoring of even remote volcanoes that are difficult to reach from the ground.

The Arxan–Chaihe volcanic field (ACVF) is a Pliocene to recent intracontinental monogenetic volcanic field. Within the ACVF, at least 47 vents are preserved in a ~2000 km² area, forming two major NE-SW trending structural elements. The youngest eruptions took place about 2000 B.P., forming two distinct complex scoriaceous and lava spatter cone systems emitting low-viscosity lava that invaded the paleo-Halaha River tributary, forming pahoehoe flow fields. This lava field forms the backbone of the geoheritage values of the Arxan UNESCO Global Geopark. The lava flow fields were believed to be almost exclusively sourced from a single vent complex around the Yanshan–Gaoshan region. However, a recent study revealed that the flow field is a result of complex eruptions with an early phase from the nearby Dahei Gou vent complex. Here, we provide evidence, based on Sentinel satellite imagery, ALOS-PALSAR-derived digital terrain model analysis, and direct field observations, that an even earlier fissure-fed eruption created another complex. This can be seen as a smaller lava flow field on the western side of the main flow field. The Dichi Lake is an iconic geosite of the geopark. It is a maar crater formed by a single explosion through an earlier lava field that erupted from a network of fissures ~2.5 km long following an NE-SW trend. The Dichi Lake geosite provides an ideal example demonstrating the effect of fissures opening in water-saturated lowlands resulting in phreatomagmatic eruptions. Moreover, our findings suggest that the youngest eruption in this region had at least three phases, probably not more than a few decades apart, along a 15 km long fissure network propagated from the SW to NE. We propose Dichi Lake as the centre of a geoheritage precinct, providing a hub of knowledge dissemination, highlighting fissure eruptions as a key type of volcanic hazard to be taken seriously in the management of the geopark.

Harrat Khaybar is an active monogenetic volcanic field in western Saudi Arabia that hosts spectacular monogenetic volcanoes and a Holocene volcanic cone with extensive lava fields. The volcanic region is a subject of intensive land use development, especially along tourism ventures, where the volcanic features are the key elements to utilize for increasing visitation rates to the region. The youngest eruption is suspected to be Holocene and occurred fewer than 5000 years ago based on the cross-cutting relationship between the youngest lava flows and archaeological sites. Lava flows are typical, from pāhoehoe to ‘a‘ā types with great diversity of transitional textural forms. Here, we recorded typical transitional lava flow surface textures from the youngest flows identified by digital-elevation-model-based terrain analysis, satellite imagery, and direct field observations. We performed lava flow simulations using the Q-LavHA plug-in within the QGIS environment. Lava flow simulations yielded satisfactory results if we applied eruptions along fissures, long simulation distances, and ~5 m lava flow thickness. In these simulations, the upper flow regimes were reconstructed well, but long individual lava flows were not possible to simulate, suggesting that morphological steps likely promoted lava ponding, inflation, and sudden deflation by releasing melts further along shallow syneruptive valley networks.

Active volcanic islands are particularly vulnerable to multi-risk natural hazards, many of which are anticipated to become more severe as a result of climate change. It is crucial to create and put into action adequate risk mitigation plans based on comprehensive long-term hazard assessments that include nature-based solutions in order to improve societal safety on these islands. Herein, we study the case of Tenerife. After a compilation and analysis of the potential resources of this island, as well as a study of its main natural hazards and how they are currently managed, we have determined that the most viable solutions are nature-based ones. Land management based on prior assessment of the island’s hazards is the key to strengthening Tenerife’s current risk mitigation plans. This will allow for a two-way relationship between the exploitation of sustainable tourism and the education of its population, both oriented toward the conservation of its geological heritage, and will promote the sustainable use of the energy and material resources currently being exploited. This contribution thus establishes the pillars from which to exploit the nature-based solutions offered by Tenerife as the only viable option for its sustainable economic development.

This work is devoted to the analysis of the background seismic noise acquired at the volcanoes (Campi Flegrei caldera, Ischia island, and Vesuvius) belonging to the Neapolitan volcanic district (Italy), and at the Colima volcano (Mexico). Continuous seismic acquisition is a complex mixture of volcanic transients and persistent volcanic and/or hydrothermal tremor, anthropogenic/ambient noise, oceanic loading, and meteo-marine contributions. The analysis of the background noise in a stationary volcanic phase could facilitate the identification of relevant waveforms often masked by microseisms and ambient noise. To address this issue, our approach proposes a machine learning (ML) modeling to recognize the “fingerprint” of a specific volcano by analyzing the background seismic noise from the continuous seismic acquisition. Specifically, two ML models, namely multi-layer perceptrons and convolutional neural network were trained to recognize one volcano from another based on the acquisition noise. Experimental results demonstrate the effectiveness of the two models in recognizing the noisy background signal, with promising performance in terms of accuracy, precision, recall, and F1 score. These results suggest that persistent volcanic signals share the same source information, as well as transient events, revealing a common generation mechanism but in different regimes. Moreover, assessing the dynamic state of a volcano through its background noise and promptly identifying any anomalies, which may indicate a change in its dynamics, can be a practical tool for real-time monitoring.

Landslide disaster risks increase worldwide, particularly in urban areas. To design and implement more effective and democratic risk reduction programs, calls for transdisciplinary approaches have recently increased. However, little attention has been paid to the actual articulation of transdisciplinary methods and their associated challenges. To fill this gap, we draw on the case of the 1993 Quebrada de Macul disaster, Chile, to propose what we label as the Geo-Social Model. This experimental methodology aims at integrating recursive interactions between geological and social factors configuring landslide for more robust and inclusive analyses and interventions. It builds upon three analytical blocks or site-specific environments in constant co-determination: (1) The geology and geomorphology of the study area; (2) the built environment, encompassing infrastructural, urban, and planning conditions; and (3) the sociocultural environment, which includes community memory, risk perceptions, and territorial organizing. Our results are summarized in a geo-social map that systematizes the complex interactions between the three environments that facilitated the Quebrada de Macul flow-type landslide. While our results are specific to this event, we argue that the Geo-Social Model can be applied to other territories. In our conclusions, we suggest, first, that landslides in urban contexts are often the result of anthropogenic disruptions of natural balances and systems, often related to the lack of place-sensitive urban planning. Second, that transdisciplinary approaches are critical for sustaining robust and politically effective landslide risk prevention plans. Finally, that inter- and trans-disciplinary approaches to landslide risk prevention need to be integrated into municipal-level planning for a better understanding of—and prevention of—socio-natural hazards.

Over geological and cultural evolutionary timescales, volcanic eruptions are relatively frequent events. In some parts of the world they are common and usually small in scale, and past human communities have been repeatedly exposed to these hazards. In other regions, they are rare and large, at times with severe consequences for contemporaneous human communities in the eruptions' near and far fields. Archaeologists have long been fascinated by these events, not least because of their power to seal and preserve archaeological sites, and the chronostratigraphical convenience provided by their isochronous tephra fallout. Regarding contemporary eruptions, volcanologists are increasingly including human science approaches to better understand societal responses, an approach often labelled social volcanology. Drawing on the existing literature on volcanic eruptions and their climatic, ecological and societal effects, I attempt to develop a systematic ‘palaeo-social volcanology’ framework that facilitates a hypothesis-driven approach to the investigation of past volcanic eruptions' impact on human societies at different distances to the eruption, and across different timescales. The Laacher See eruption and its impact on contemporaneous Final Palaeolithic hunter-gatherers in northern Europe serves as an example. In concluding, I reflect on how such case studies of ancient calamities can be made relevant in contemporary settings.

Volcanic geoheritage is an emerging field with limited assessments and particular methodological approaches worldwide. The scarcity of volcanic geomorphosite evaluation is higher in tropical countries, particularly developing ones such as Costa Rica and Cameroon. To contribute to reducing this gap in the literature, we evaluate and compare the geomorphosites of the Irazú and Eboga volcanoes, which are renowned massifs for both their natural and their cultural qualities in their respective countries. We used an integrated approach for the inventory and management of volcanic heritage crossing geomorphological and cultural information in order to promote geotourism among all their geodiversity. The study shows that Irazú and Eboga volcanoes are representative for Costa Rica and Cameroon. This information is critical for the promotion of geotourism to a larger public through geoconservation. Our results demonstrate the importance and value that these volcanoes have in promoting and preserving geoheritage in Costa Rica and Cameroon. It is our hope that these outputs may encourage new research in regions less studied tropical volcanic regions. The methodology used proves to be a useful tool in evaluating geomorphological heritage in tropical volcanic environments. Consequently, our study aims to enhance the state of the art of tropical volcanic geoheritage.

Volcanic areas create spectacular landscapes that contain a great diversity of geoheritage. The study of this geoheritage enables us to inventory, characterise, protect and manage its geodiversity. The Canary Islands are a group of subtropical active volcanic oceanic islands with a great variety of magma types and eruption dynamics that give rise to a wide diversity of volcanic features and processes. The aim of this paper is to identify, for the first time, the diversity of volcanic geoheritage of the Canary Islands and to appraise the protection thereof. To this end, a geomorphological classification is proposed, taking into account the features and processes directly related to volcanism, such as those resulting from erosion and sedimentary processes. The main findings demonstrate that the volcanic geoheritage of the Canary Islands is extremely varied and that this geodiversity is safeguarded by regional, national and, international protection and management frameworks. Even so, and given the enormous pressure of coastal tourism on the coastlines of the islands, we believe that continuing efforts should be made to conserve and manage their volcanic and non-volcanic geoheritage, so that these places can continue to be enjoyed in the form of geotourism.

One of the best known places on Earth where volcanology meets archaeology and history is the volcanic island of Santorini (Thíra), Greece. It is famous for the cataclysmic Late Bronze Age (Minoan) Plinian eruption which destroyed the Minoan culture that flourished on the island. Hosting a central, flooded caldera bay and, within that, the active islands of Palaea and Nea Kameni, Santorini volcano has been the focus of international research efforts for over one and a half centuries. In this paper, we summarize recent findings and related ideas about the Minoan physiography of the island, also known as Strongyli, from a volcanological, geomorphological and archaeological point of view. As proposed as early as the 1980s, a central caldera bay existed prior to the Late Bronze Age. Probably characterised by a smaller size and located in the northern part of the present-day caldera, this earlier caldera bay was formed during the previous Plinian eruption – called Cape Riva eruption – c. 22,000 years ago. Within the caldera bay, a central island, Pre-Kameni, existed, named after the present-day Kameni Islands. High-precision radioisotopic dating revealed that Pre-Kameni started to grow c. 20,000 years ago. Whereas volcanologists have accepted and refined the caldera concept, archaeologists have generally favoured the theory of an exploded central cone instead of a pre-existing central caldera. However, analysis of the Flotilla Fresco, one of the wall paintings found in the Bronze Age settlement of Akrotiri, reveals the interior of a Late Bronze Age caldera that may be interpreted as a realistic landscape. Approximately 3600 years ago, the island of Strongyli was destroyed during the explosive VEI = 7 Minoan eruption. Pre-Kameni was lost by this eruption, but its scattered fragments, together with other parts of Strongyli, can be recovered as lithic clasts from the Minoan tuffs. On the basis of photo-statistics and granulometry of the lithic clasts contained in the Minoan tuffs, complemented by volumetric assessment of the erupted tephra and digital elevation model (DEM) analysis of alternative models for the pre-eruptive topography, the volume of Pre-Kameni can be constrained between 1.6 and 3.0 km³, whereas the volume of the destroyed portion of the ring island of Strongyli between 9.1 and 17.1 km³. Of these, the larger values are considered more realistic, and imply that most of the destroyed part of Strongyli was incorporated as lithic components in the Minoan tuffs, whereas up to 3 km³ of Strongyli might have been downfaulted and sunken during caldera formation and is not accounted for in the lithics.

The Flinders Ranges in the north and Mount Lofty Ranges in the south form a continuous highland chain extending ∼1000 km in eastern South Australia. This region corresponds to outcropping rocks of the Neoproterozoic to Cambrian Adelaide Rift Complex. The semi-arid ranges of the north with their historic mining heritage and the agriculture and vineyards of the south are heavily promoted as iconic natural and cultural tourism attractions, increasingly combining with indigenous landscape stories. With the exception of Arkaroola and Kangaroo Island, these regions are linked by the 600 km Heysen Walking Trail and adjacent Mawson Cycle Trail. Research on the Ediacara fossil biota in the Flinders Ranges has raised public awareness of geological history and the early evolution of life on Earth and developed into a multi-site Flinders Ranges World Heritage Nomination project. This is supported by the South Australian Government as part of its Nature Tourism programme to provide opportunities for conservation, education, tourism initiatives and local employment, all of which are aspirations of the United Nations Educational Scientific and Cultural Organisation (UNESCO). South Australia has a World Heritage Fossil site at the Naracoorte Caves complex, which is a compact National Park with many staff and security for laboratories and underground fossil deposits. The multi-site World Heritage proposal for the semi-remote Flinders Ranges presents a very different approach for protection and public visitation. Following an emerging global trend for geotourism and developing geotrails, this paper proposes a 400-km loop geotrail across the region linking the nominated Flinders World Heritage elements with other ‘Geological Monuments’, listed State Heritage and historical sites. This strategy has the potential to involve wider community interest, engagement, support and involvement in its management. The concept would be a natural link to the Heysen and Mawson trails, both named after prominent South Australians with strong links to the Flinders Ranges landscape. It could be named the Ediacara Geotrail, Sprigg Geotrail or Arkaroo Geotrail after the indigenous dreamtime creator of the northeastern Flinders Ranges.

The Cenozoic harrats (lavafields) of western Arabia constitute one of the major volcanic areas of the world. Recent precise chronometric dating of volcanic rocks in Harrat Rahat makes it possible to outline a detailed chronology of volcanic activity. Likewise, recent advances in archaeology have demonstrated that early humans repeatedly occupied the Arabian Peninsula in the Pleistocene. Most archaeological sites in Arabia correlate with phases of increased rainfall, such as interglacials. However, we should be cautious about reducing the prehistory of Arabia to simply the story of rainfall fluctuation. This paper explores the impacts of volcanism on human populations in Arabia, as a case study of causality and scale in human-environment interactions. Periodic environmental ‘windows of opportunity’ allowed early human groups to expand into western Arabia. However, the western highlands are also home to volcanically active areas that saw repeated eruptions. In the Holocene a major eruption occurred in western Arabia around every 300 years, and the emerging evidence for Pleistocene volcanism demonstrates repeated major eruptions at the same times as early humans were occupying the area. As well as offering a review of human-volcanism interactions in Arabian prehistory, a model is proposed in which volcanic activity in western Arabia may have facilitated further population dispersal. As well as negative health impacts as a ‘push factor’, a balanced perspective on the impacts of volcanism, and associated phenomena such as earthquakes, emphasises possibly positive impacts in terms of factors such as water availability and the formation of fertile volcanic soils. These positive impacts may have offered ‘pull factors’, and facilitated regional occupation longer than would be predicted based on climatic variables alone. This framework offers not only an explanation for some of the characteristics of the Arabian archaeological record, but potentially offers part of the explanation for how early human populations were able to pass through the Saharo-Arabian arid belt from our African birthplace to populate the rest of the world.

Volcanic eruptions and interactions, with the landforms and products these yield, are a constant feature of human life in many parts of the world. Seen over long timespans, human–volcano interactions become stratified in sedimentary archives containing eruptive products and archaeological remains. This review is concerned with charting the overlapping territory of volcanology and archaeology and attempts to plot productive routes for further conjoined research. We define archaeological volcanology as a field of study that brings together incentives, insights, and methods from volcanology and from archaeology in an effort to better understand both past volcanism as well as past cultural change, and to improve risk management practices as well as the contemporary engagement with volcanism and its products. There is an increasing appreciation that understanding these human impacts and manifold human-volcano interactions requires robust multi-, inter- or even trans-disciplinary collaboration. Our review is written in the hope of providing a clearinghouse resource that (i) maps the many forms of past human-volcano interactions, (ii) provides study design templates for how to integrate archaeological perspectives into investigations of past volcanism, and (iii) makes suggestions for how the insights gained from such an archaeological volcanology can be integrated into reducing contemporary and future vulnerability amongst at-risk communities.

San Miguel volcano (or Chaparrastique), one of El Salvador's most active volcanoes, has erupted 28 times in the past 431 years (historical period). The majority of historical eruptions have been Strombolian (VEI 1–2) that have occurred from the central vent and have generated ashfall and ballistics, but some of them (8) have been effusive flank eruptions, mainly producing lava flows of basaltic and basaltic-andesite composition. Secondary lahars generated by remobilization of the young tephra are also common at San Miguel volcano. Using the information for these historical as well as prehistoric eruptions and applying probabilistic tools designed for volcanic-hazards assessment, we simulated: (1) the five most likely scenarios (ashfall scenarios, local-moderate extent, and VEI 1–2); (2) other probable scenarios related to lava flows, based on the historical record of the volcano; (3) other possible scenarios related to pyroclastic density currents (PDCs) with similar characteristics to those that occurred during its eruptive history; and (4) the most hazardous scenarios (ashfall, lava flow, PDC) that have been identified from its prehistoric geological record. Finally, we construct a qualitative integrated volcanic hazard map through the combination of the simulated scenarios. This study was developed with the aim of improving the existing volcanic-emergency plan. It should serve to improve the collaboration and coordination between scientists, the national observatory (OA-MARN), and the civil protection agency of San Miguel municipality, and will help to strength this cooperation to respond effectively to future volcanic crises.
