El volcán Popocatépetl ha estado muy activo desde el 21 de diciembre de 1994. Su actividad, a lo largo de los casi 30 años de actividad eruptiva ha sido de carácter explosivo (principalmente de tipo vulcaniano), alternado con actividad efusiva (construcción de domos de lava). La actividad explosiva ha producido columnas de cenizas con diferentes tamaños, de hasta ~20 km de altitud y con una dispersión que ha llegado hasta los EUA. Sin embargo, la lluvia de cenizas importante se ha restringido a los ~65 km alrededor del cráter con evidencias de caída de cenizas en las ciudades de México y Puebla principalmente. El monitoreo de la actividad eruptiva ha sido llevado a cabo por el Centro Nacional de Prevención de Desastres, conjuntamente con investigadores de la Universidad Nacional Autónoma de México, principalmente del Instituto de Geofísica, durante los años que lleva en ac...

The development of volcanology in Latin America is marked by a common regional scenario, with countries sharing borders, socio-cultural characteristics and facing similar scientific challenges. This scenario illustrates the need to create and promote regional networks. In this abstract we present the Jóvenes Volcanólogos Latinoamericanos (JVLA) network, a specific strategy that gathers early career volcanologists from Latin America and aims to strengthen volcanology in the region by encouraging the active participation of new generations. A benchmark in the construction of this network was the CoV9 conference (2016, Chile), where the 1st meeting of Young Latin American Volcanologists took place. As a response to the needs identified during that meeting, JVLA, together with the Asociación Latinoamericana de Volcanología (ALVO), developed an internship program in volcano observatories ...

Permafrost is present in the high-altitude mountains of the Trans-Mexican Volcanic Belt as well as the Andes, even in the extreme dry Atacama highland. The permafrost and active layer termal state are characterized at Latin American Permafrost Network study sites. Ice rich or extremely dry permafrost was observed during drilling operations from Mexico (Pico de Orizaba, 5636m a.s.l. Iztaccíhuatl, 5230m a.s.l.), Colombia, Ecuador (Chimborazo, 6263m a.s.l.), Peru (Coropuna 5250 m a.s.l., Ampato 5850 m a.s.l., Chachani 5600 m a.s.l.) including the highest human habitation in the world: La Rinconada 5100 m a.s.l., Bolivia (Chacaltaya 5300 m a.s.l. where glacier disappeared in 2005), and the Chilean/Argentinian border (up to 6750 m a.s.l. including Parinacota, Aucanquilcha, Ojos del Salado, Llullaillaco, Tupungato and Tupungatito). The Lower Limit of Alpine Permafrost (LLAP) is redrawn from t...

Volcanic plumes are common and far-reaching manifestations of volcanic activity during and between eruptions. Observations of the rate of emission and composition of volcanic plumes are essential to recognize and, in some cases, predict the state of volcanic activity. Measurements of the size and location of the plumes are important to assess the impact of the emission from sporadic or localized events to persistent or widespread processes of climatic and environmental importance. These observations provide information on volatile budgets on Earth, chemical evolution of magmas, and atmospheric circulation and dynamics. Space-based observations during the last decades have given us a global view of Earth's volcanic emission, particularly of sulfur dioxide (SO2). Although none of the satellite missions were intended to be used for measurement of volcanic gas emission, specially adapted alg...
