SummaryIn the last 30 years more than 100,000 people have been affected by volcanic activity along Latin America. The lahars occurrence correspond to a secondary process derived from remobilization of superficial deposits (pyroclastic flows, hash Flows); and the 60 % of lahars deposits over stratovolcanoes in Latino America are associated to high rainfall episodes. In this project we propose to explore the TerraSAR-Xdata capabilities from a regional study about recognition of spatial patterns of lahars deposits over the most active stratovolcanoes in Latin America using historical TerraSAR-X data in Strip Map and Scansar mode. According with the archieve TerraSAR-X data, the selected volcanoes is follows: Colima and Popocatepetl Volcanoes in Mexico, Fuego Volcano in Guatemala, San Cristobal-La Casita Volcanic Complex in Nicaragua, Cotopaxi Volcano in Ecuador, and Nevado del Huila, Nevado del Ruiz in Colombia, and Villarica Volcano in Chile. This analysis may be useful for quantity lahar maxim events and its implications into assessment volcanic hazards in heterogeneous stratovolcanoes (in a regional scale).
