However, the choice of measurement and geostatistical methodologies may affect individual FCO2

St. Helens eruption. The most recent of these was a caldera forming event ~4300 yr B.P. Besides frequent Plinian-type eruptions, the sector collapse-linked debris avalanches are the greatest risk to the surroundings. The CVC shows a southern migration of activity, the oldest edifice being El Cántaro, active between 1.6-1 Ma B.P. Subsequently, volcanism moved 15 km south to the territory of Nevado de Colima, and more recently to its current location, further 6 km to the south. In this work, we present new results analysing a 5-m resolution Digital Elevation Model (DEM) to describe CVC's actual geomorphological features and to infer their origin, focusing on Nevado de Colima. Analysing DEM we observed significantly higher ridge and valley density on the western slopes. This may imply an older (and more dissected) part of the ...
