High enthalpy geothermal fields are typically associated with magmatic intrusions providing the heat source that makes the system working. To identify and locate these features, geothermal exploration generally uses expensive, time-consuming approaches that could also require complex logistics. Here we present the result of a pilot study carried ou...

The orogenic growth of the Domeyko Cordillera was induced by a positive tectonic inversion. In this work, we have validated this interpretation from new field data, which were combined with 2‐D reflection seismic profile interpretations obtained along the Central Andes forearc of northern Chile. To compare with this information, we performed a new...
Article
Caldera volcanoes are complex geological systems that show, during and after their formation, a wide variability in terms of eruptive styles, magmatic and geochemical evolution, and volcanic structures. Los Humeros Volcanic Complex (LHVC) is a key area where to study these factors. It is located in the easternmost sector of the Trans-Mexican Volcan...

Full-text available
The CO2-(N2)-rich pressurised Caprese Reservoir (Northern Apennines, central Italy) is a structural system controlled by a subsurface fold anticline. Mud volcano-like structures and cold gas seeps lie along steep, ~NE-trending faults, which are intimately connected to the deep fluid reservoir. In August 2010, five vents erupted mud flows after a lo...

The Mugello Basin (North-Eastern Tuscany) is an intermontane basin of the Northern Apennines (Italy) with a well-documented record of seismicity; the two major historical earthquakes occurred in 1542 (Mw = 6.0) and in 1919 (Mw = 6.4). In this study, we integrate different seismic catalogs spanning the 2005–2019 time interval, and complement these d...
Article
Full-text available
The Main Ethiopian Rift (MER) represents an area where volcanism and tectonics interact to create closely linked volcano-tectonic features. This linkage is paramount in the axial portion of the rift, where magmatic segments localize several large peralkaline eruptive centres. Many of them evolved into caldera collapse (the best preserved of which a...
Article
Full-text available
In recent years, new approaches for developing earthquake rupture forecasts (ERFs) have been proposed to be used as an input for probabilistic seismic hazard assessment (PSHA). Zone-based approaches with seismicity rates derived from earthquake catalogs are commonly used in many countries as the standard for national seismic hazard models. In Italy...
Article
Full-text available
Scaled analogue models explored the role of different boundary conditions in intracaldera resurgence processes. Models investigated the role of magma intrusion depth (ID) (Series 1), asymmetric and symmetric caldera collapse (Series 2), as well as the presence of existing discontinuities in the pre-volcanic substratum (Series 3) on the style of cal...
Article
Caldera collapse received large attention during the last decades and was widely studied using various approaches, spanning from field-geology to numerical and analogue modelling. Analogue models allow to reproduce caldera collapse deformation, providing information otherwise difficult to obtain during such an extremely transient geological process...
Article
Earthquakes can influence the activity of mud volcanoes and other fluid expulsion systems, which may erupt or change their activity shortly after the seismic event. This study investigates the influence of static and dynamic stresses, produced by some important earthquakes in Taiwan, on fluid expulsion systems that have coseismically responded to s...
Article
Full-text available
Since caldera collapse deformation is extremely difficult to study in real time - due to the high deformation rates that characterize this process and the difficult access to the caldera structures-analogue modeling has been widely used during past decades to integrate field data and, more recently, remote-sensing data (e.g., InSAR). However, the r...

In offshore settings, the vertical migration of fluids may generate different structures on the seafloor and in the subsurface that can be readily imaged by multibeam and seismic data, respectively. On the floor, circular to elliptical depressions up to kilometers wide and hundreds of meters deep have been described as pockmarks. They are commonly...
Article
We explore the capability of interconnected sills to transport magma in the shallow crust, as well as the effect of simultaneous and temporally separated multiple magma emplacement on deformation pattern. We analyze this process through analogue models run with synchronous or diachronous magma injection from different, aligned inlets. Experimental...
Article
Full-text available
Continental rifting is a geodynamic process that involves the breakup of the crust, and may eventually evolve to sea floor spreading. Although it is often assumed to be a product of orthogonal divergence, continental rifting may result from oblique extension, and in several cases it is related to the rotation of plates or crustal blocks about a ver...
Article
During the last decades, central Italy has been struck by severe seismic sequences. Some authors have suggested that inherited thrust faults may have played an important role in controlling the recent-to active extensional deformation in the area, particularly during the 2016 Central Italy seismic sequence. To explore this hypothesis, we performed...
Article
Earthquakes can occasionally trigger the eruption or increase the activity of mud volcanoes and other fluid seepage systems. One long pending question is how static and dynamic stress changes can trigger eruptions of fluid expulsion features and modulate their activity. This study addresses the potential role of static and dynamic stress changes by...
Article
The tectonic evolution of the Andean forearc in northern Chile has commonly been related to superimposed deformational events associated with different tectonic settings. The eastern Domeyko Cordillera and the Salar de Atacama Basin on the inner Andean forearc, have been widely investigated, and several alternative tectonic models including extensi...

Caldera collapse is a complex geological process that, due to its quasi-instantaneous nature, remains difficult and elusive to investigate. Because of this, several numerical and analogue modelling experiments have been used to analyse this process during the last decades (e.g., Geyer & Martí, 2014, and reference therein): these approaches are inde...

The Trans-Mexican Volcanic Belt (TMVB) is a large-scale, NW to SE trending volcano-tectonic feature extending through central Mexico for a length of more than 2000 km. Its genesis is strictly related to the interaction between the subducting Rivera and Cocos plates and the North America plate, as the eastward propagation of volcanism is considered...
Article
We have performed a series of sandbox models addressing the influence of sand mixtures (quartz and feldspar sand in different proportions) with different grain-size on the development of normal faults. The overall model evolution suggests that fault orientation, width of the deformed area, and average subsidence are not significantly influenced by...

Article
Mud volcanism is known to be strictly linked to tectonic structures, since they have the ability to trap hydrocarbon and other fluids, and eventually induce them to migrate from a deep reservoir (e.g. sited into an anticline core, where large overpressures may be generated), to the surface. A central theme is how fluids can migrate upward, and whic...
