Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map
Earth and Space Science, Volume 12, Issue 11, November 2025.Abstract Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits. Here we analyze the TanDEM‐X Digital Change Map (DCM), which compares the DEM produced during 2010–2015 with satellite acquisitions collected in 2016–2022.

Role of Sparsely Glacierized Basins and Groundwater in Semiarid Andes Periglacial Headwaters
Hydrological Processes, Volume 39, Issue 10, October 2025.This study highlights for the first time the role of the Andean low‐glacierized headwater basin in providing significant water flow to the outlet discharge (20%–30%) with relatively long residence times (several decades). It can be explained by unknown permafrost bodies, which must be better characterized to manage water in a changing climate in ...
