The Geological Survey of Japan, AIST will start a project to make a database of location information on volcanic crater and eruption centers in active volcanoes in Japan. The target volcanoes of the database are the Japan Meteorological Agency's constantly observed volcanoes. A high-density DEM productid by airborne laser scanning is used for topographic interpretation. A Red Relief Image Map is also used to interpret the topography. For each crater / eruption center show the certainty from the topographical features and volcanic geological information. On the presentation, we will show an overview of the project and also report on the results of some volcanoes.
