The Calbuco volcano in southern Chile erupted on Wednesday, 22 April 2015 for the first time in over 42 years sending a plume of ash into the sky. The eruption triggered a Red Alert in the Los Lagos Region of Chile. Thousands of people within a 20 km radius of the volcano have been evacuated. The International Charter Space and Major Disasters has been activated, where the DLR/ZKI contributes with the delivery of TerraSAR-X and RapidEye data and value added products. The volcano erupted twice in less than 24 hours. The first eruption on April 22, 2015 lasted over an hour, leaving a 10 km ash cloud. There had been no warning of the eruption, as the volcano had been dormant for decades and no activity had been expected. The second eruption occurred seven hours later on the following morning and early reports indicate that it was on the same scale as the first eruption.
