The Paricutin-Tancítaro region (PTR) within the Michoacán-Guanajuato monogenetic Volcanic Field (MGVF) is characterized by a large stratovolcano, Tancítaro enclosed in a dense distribution of monogenetic volcanoes, mainly scoria cones, that includes the well-known Paricutin. The succession of seismic swarms beginning 54 years after the birth of Par...
The Michoacán-Guanajuato Volcanic Field (MGVF) in central-western Mexico, with more than 1,000 monogenetic volcanoes, has been well known since 1943 when an eruption formed the Paricutín volcano, 11 km to the NW of the summit of Tancítaro stratovolcano. In the highly fractured zone around Tancítaro, referred to as the Paricutín-Tancítaro region (PT...
Seismic swarms in a volcanic field can be indicators of the movements of volcanic activity and stagnant magma in the Earth’s crust. In the Tancítaro-Parícutin volcanic region, to the west of the Michoacán-Guanajuato volcanic field in Mexico, at least six seismic swarms have occurred in the last 25 years. However, greater precision is still required...

Se presenta el análisis numérico de la dispersión de un contaminante gaseoso en un medio poroso infinito formado de un arreglo ordenado de partículas con diferentes razones de diámetros (DR). El intervalo cubierto fue 0.2<DR<0.8, el cual corresponde a variaciones sistemáticas en el grado de expansión-contracción de las trayectorias de poro, no incl...
Geochemical and mineralogical analyses data are presented for ignimbritic deposits from the Bambouto volcano. These deposits are characterized by their welded and non-welded massive lapilli tuff and massive lithic breccias facies. The ignimbrites generally display vitroclastic and/or eutaxitic texture characterized by whole or broken minerals, suba...
This paper presents a comparative study of volume average predictions between low Reynolds number (LRN) turbulence models: Abe-Kondoh-Nagano (AKN), Lam-Bremhorst, Yang-Shih, standard k-, and k-ω. A porous medium, which represents conditions in which the flow path changes rapidly, was defined as an infinite array of square cylinders. In addition, to...
Se estudió de manera comparativa la respuesta de los modelos de turbulencia Abe Nagano Kondoh (ANK), Yang Shih (YS), Lam Bremhorst (LB), k-ω de bajo Re (LR- k-ω) y el k-ε Standard (STD) en dominios de poro definidos arreglos periódicos de cilindros infinitos con sección transversal cuadrada y circular. El número de Reynolds (Re) fue variado de 1×10...
In this work, the effect of low salinity water flooding (LSWF) on capillary pressure and relative permeability is studied at pore scale. For this purpose, a pore-scale model implemented on OpenPNM is developed to describe fluid flow, salinity transport and wettability change in a pore network. The effect is studied by considering high salinity wate...
Volcán de Colima has one of North America's highest rates of eruption, producing a wide range of eruptions ranging from effusive episodes to Plinian phases and sector collapses. Such activity potentially endangers over 350,000 people dwelling within the reach of volcanic products and runouts. To widen the hazard assessment derived from this activit...
After 70 years of quiescence Popocatépetl volcano began a new episode of activity in 1994, which is still ongoing. The predominant activity has been a succession of dome emplacements followed by sequences of dome-destruction explosions producing prominent volcanic ash columns. Moreover, relatively large eruptive columns have also been produced duri...
El volcán Popocatépetl inició un episodio eruptivo en 1994 después de un periodo de 70 años de quietud. Este episodio, que persiste hasta el momento, se caracteriza por una secuencia de episodios sucesivos de emplazamiento y destrucción de domos de lava. Esta actividad va acompañada por la producción de columnas eruptivas de ceniza que alcanzan alt...

Pore network models have been applied for predicting petrophysical properties at pore scale. From a geometry point of view, basically a pore network and pore and throat size distributions are required for pore network modeling. Although different pore network models have been constructed using data extracted mainly from images, it is not always pos...
Pore network modeling is a technique that has been booming in recent years, and several authors have used it to obtain properties as absolute permeability, relative permeabilities and capillary pressures, which are common obtained from laboratory tests and/or experimental correlations. The scope of this work is to model flow and immiscible displace...
Most volcanic hazard studies focus on magmatic eruptions and their accompanying phenomena. However, hazardous volcanic events can also occur during non-magmatic unrest, defined as a state of volcanic unrest in which no migration of magma is recognised. Examples include tectonic unrest, and hydrothermal unrest that may lead to phreatic eruptions. Re...
Popocatépetl volcano reawakened in 1994 after nearly 70 years of quiescence. Between 1996 and 2015, a succession of at least 38 lava domes have been irregularly emplaced and destroyed, with each dome reaching particular volumes at specific emplacement rates. The complexity of this sequence is analyzed using statistical methods in an attempt to gain...
The ongoing eruptive activity of Popocatépetl volcano has been characterized by emplacement and subsequent destruction of a succession of lava domes. Between the onset of the current eruption in 1994 and the time of this submission, 38 episodes of lava dome formation and removal have been identified. Each dome has showed particular features related...
The statistical analysis of size-qualified volcanic eruption time series is an essential step for the assessment of volcanic hazard. Such series generally describe complex processes that may be time dependent, involving different types of eruptions over a wide range of timescales. The hazard assessment thus requires a characterization of the erupti...
The continuous background seismic activity contains information on the internal state of a volcanic system. Here, we report the influence of major regional tectonic earthquakes (M > 5 in most cases) on such state, reflected as changes in the spectral and dynamical parameters of the volcano continuous seismic data. Although changes do not always occ...
The Canary Islands are an active volcanic region densely populated and
visited by several millions of tourists every year. Nearly twenty
eruptions have been reported through written chronicles in the last 600
years, suggesting that the probability of a new eruption in the near
future is far from zero. This shows the importance of assessing and
moni...

The El Chichón volcano (Chiapas, México) most recent eruption occurred in 1982 causing the worst volcanic disaster in the recorded history of Mexico. Prior to the eruption, El Chichón volcano was not considered a very hazardous volcano, a perception mostly caused by the low eruption rate of the past eruptions. The correct assessment of volcanic haz...
The assessment of volcanic hazard is the first step for disaster mitigation. The distribution of repose periods between eruptions provides important information about the probability of new eruptions occurring within given time intervals. The quality of the probability estimate, i.e., of the hazard assessment, depends on the capacity of the chosen...
The volcanic-eruption time series contain information of complex volcanic processes, and they represent one of the main tools for the assessment of the volcanic hazard. Unfortunately, most of the available series, capable to describe the whole range of eruption magnitudes, are usually confined to historical data, since the smaller eruptions do not...
The probabilistic analysis of volcanic eruption time series is an essential step for the assessment of volcanic hazard and risk. Such series describe complex processes involving different types of eruptions over different time scales. A statistical method linking geological and historical eruption time series is proposed for calculating the probabi...
Volcanic hazard is defined in terms of the probabilities of occurrence of eruptions and their potentially destructive manifestations. These probabilities may be estimated analyzing the sequence of past eruptions in a given volcano, characterizing the eruptions by size and assuming that the impact and effects of an eruption are proportional to both,...
The volcanic-eruption time series are sequences describing processes of great complexity representing one of the main tools for the assessment of the volcanic hazard. The analysis of such series is thus a critical step in the precise assessment of the volcanic risk. The study of low-magnitude eruption sequences, containing larger data populations c...
