The Colima Volcanic Complex trends in a nearly N-S direction in western Mexico, and one of its structures, Colima volcano, is the most historically active volcano in the country. Immediately to the N, there is another volcanic center called El Cántaro volcano, whose activity started around 1.7 Ma in its N portion and migrated to the S in various episodes. Volcanic activity migrated further south, from El Cántaro to the Colima Volcanic Complex where the southernmost manifestation, Hijos del Volcán domes, is located on the south slope of Fuego volcano. The above date appears to mark initiation of the rather continuous volcanic activity in the area. It has been noted that these volcanic manifestations lie on, or near the Rivera-Cocos inland plate boundary. Colima's Fuego volcano is also the closest to the Middle America Trench, among the polygenetic volcanoes in Mexico. We submit that the anomalous location of volcanism in this area originates in an anomalous subduction process of the Rivera and Cocos plates and evoke a tectonic model, proposed elsewhere, to support the idea. Modeling gravimetric and aeromagnetic data we locate the magma chambers of the Fuego (active) and Nevado (extinct) volcanoes within a 65 mGals negative Bouguer anomaly elongated in a nearly N-S direction. The corresponding aeromagnetic map displays a magnetic high over the southern portion of the Fuego volcano edifice. We found two additional, associated structures whose anomalies have not been previously reported, which appear to follow the southward magmatic migration pattern. One of them is a collapse structure with a circular topographic expression, and the southernmost is a low-density intrusion ~1 km below sea level, associated with a moderate topographic bulge at the surface that we interpret as a magma body. Five lines cross the anomalies; gravimetric and magnetic fields are concurrently modeled along them to locate the magmatic bodies. In addition to the 2-D models we perform 3-D gravimetric and

Abstract. The impact of ash-fall on people, buildings, crops, water resources, and infrastructure depends on several factors such as the thickness of the deposits, grain size distribution and others. Preparedness against tephra falls over large regions around an active volcano requires an understanding of all processes controlling those factors, and a working model capable of predicting at least some of them. However, the complexity of tephra dispersion and sedimentation makes the search of an integral solution an almost unapproachable problem in the absence of highly efficient computing facilities due to the large number of equations and unknown parameters that control the process. An alternative attempt is made here to address the problem of modeling the thickness of ash deposits as a primary impact factor that can be easily communicated to the public and decision-makers. We develop a semi-empirical inversion model to estimate the thickness of non-compacted deposits produced by an explosive eruption around a volcano in the distance range 4-150 km from the eruptive source.

“…Es también durante el Cuaternario que se construyen los principales estratovolcanes de la FVTM occidental. El complejo volcánico de Colima, emplazado en la terminación meridional del rift homónimo, representa por mucho el mayor volumen de material volcánico emplazado en la región (~700 km 3 ; Robin et al, 1987). El resto de los estratovolcanes tienen volúmenes menores a los 100 km 3 (Tequila, Ceboruco, Tepetiltic, Sangangüey, Las Navajas y San Juan), y se alinean a lo largo de fallas regionales de orientación WNW-ESE que defi nen la frontera norte del bloque Jalisco (Figura 3).…”

C i e n A ñ o s ResumenLa extraordinaria diversidad magmática de la Faja Volcánica Transmexicana está controlada (directa o indirectamente) por dos placas oceánicas independientes cuyos parámetros geofísicos y composicionales se modifi can constantemente a lo largo de la trinchera, por un régimen tectónico esencialmente distensivo que opera con distinta intensidad sobre la placa continental, por un basamento cortical con diferentes edades, espesores y composiciones, y por una fuente mantélica primaria de composición extremadamente variable que ha sido infl uenciada, en mayor o menor medida, por los agentes químicos derivados de la subducción. El régimen tectónico convergente y, en consecuencia, el arco magmático, tampoco han evolucionado de forma homogénea a lo largo su historia, sino que han mostrado transformaciones notables en su posición, geometría y composición. Por estos motivos, la Faja Volcánica Transmexicana es el resultado de uno de los sistemas tectónicos convergentes más complejos del planeta, el objeto de más de un siglo de investigaciones científi cas, y también el centro de las controversias más notables sobre la geología mexicana.Palabras clave: Faja Volcánica Transmexicana, México, subducción, arco magmático, petrología ígnea, manto, corteza.
