Post préparé par Marine Bouchet pour le blog Kalideos Alpes (version originale) Les séries temporelles d’images optiques des satellites Sentinel-2 permettent un suivi de la surface enneigée à une résolution spatiale de 20 m tous les 5 jours (en l’absence de nuages). Le CNES et le CESBIO développent, depuis 2015, une chaîne Let It Snow […]
Villarrica volcano is one of the most active volcanoes in the Chilean Andes. A colleague of mine (Esteban Alonso) told me that last week he went ski touring up there and when he reached the summit he could see the bubbling lava in the bottom of the crater, and could even feel its heat…
