Volcano observations with aster and ASTER Image Database for Volcanoes

ASTER was launched on December 1999 and has observed many volcanic eruptions. Through these observations, ASTER´s ability to monitor volcanic activities, such as thermal anomalies, topographic changes, volcanic gases, among others, has been validated. A web-based ASTER Image Database for Volcanoes that contains all ASTER images of 964 volcanoes is developed and released. All ASTER images that include a part of the 20 km by 20 km area centered on the geographic location of volcano are stored in the database. Usually newly acquired image is added to the database within a week. It helps to promote the use of ASTER images to volcanologists.
