Argentina es un extenso país con numerosas evidencias de actividad volcánica. Sin considerar el volcanismo antártico (e.g. Isla Decepción, en las Shetland del Sur), en el país existen 38 volcanes con registro de actividad holocena, 20 enteramente en territorio argentino y 18 en el límite internacional con Chile (García y Badi, 2021). La totalidad de estos sistemas volcánicos activos se encuentran emplazados en el extremo occidental del territorio. Sin embargo, al pensar en las posibles consecuencias de la actividad volcánica en el país, también deben considerarse los más de 70 volcanes activos ubicados íntegramente en territorio chileno (Amigo, 2021). Más allá de los procesos circunscritos a las inmediaciones de los edificios volcánicos (e.g. corrientes piroclásticas, flujos de lava, lahares), el principal peligro volcánico para el territorio argentino es la caída de t...

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 ...

La Asociación Latinoamericana de Volcanología (ALVO) fue fundada el día 7 de noviembre del año 2010 en Manizales, Departamento de Caldas, Colombia (Granados et al., 2015a, b; Rodríguez et al., 2019). Con un grupo reducido de miembros fundadores, la ALVO quedó establecida e inició operaciones con un primer Consejo Directivo que sentó las bases para un camino de colaboración, reflexión y oportunidades en la región latinoamericana. Hoy en día la asociación cuenta con más de 1500 miembros, repartidos en toda la región Latinoamericana. En números aproximados, se registran 540 miembros para la región de Sudamérica Sur (Argentina, Brasil, Bolivia, Chile, Paraguay y Uruguay), 460 para la región de Sudamérica Norte (Colombia, Ecuador, Guyana, Perú, Surinam y Venezuela), 310 para la región de Centroamérica y el Caribe (Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica,...

During explosive volcanic eruptions, large quantities of tephra can be dispersed and deposited over wide areas. Following deposition, subsequent aeolian remobilisation of ash can potentially exacerbate primary impacts on timescales of months to millennia. Recent ash remobilisation events (e.g., following eruptions of Cordón Caulle 2011; Chile, and Eyjafjallajökull 2010, Iceland) have highlighted this to be a recurring phenomenon with consequences for human health, economic sectors, and critical infrastructure. Consequently, scientists from observatories and Volcanic Ash Advisory Centers (VAACs), as well as researchers from fields including volcanology, aeolian processes and soil sciences, convened at the San Carlos de Bariloche headquarters of the Argentinian National Institute of Agricultural Technology to discuss the “state of the art” for field studies of remobilised deposits as...

The Central Volcanic Zone of the Andes (CVZA) extends from southern Peru, through the Altiplano of Bolivia, to the Puna of northern Chile and Argentina, between latitudes 14–28° S of the Andean cordillera, with altitudes rising up to more than 4000 m above sea level. Given the large number of active volcanoes in this area, which are often located close to both urban areas and critical infrastructure, prioritization of volcanic risk reduction strategies is crucial. The identification of hazardous active volcanoes is challenging due to the limited accessibility, the scarce historical record, and the difficulty in identifying relative or absolute ages due to the extreme arid climate. Here, we identify the highest-risk volcanoes combining complementary strategies: (i) a regional mapping based on volcanic hazard parameters and surrounding density of elements at risk and (ii) the applic...
