A joint dense seismic observation experiment was conducted during the period from July 2005 to July 2007 in cooperation of researchers of national universities and Japan Meteorological Agency (JMA) under the national project for prediction of volcanic eruption. A main subject of this project is clarification of subsurface velocity structure of Asama volcano and of surrounding area penetrating to the upper mantle around 100km deep. We installed 15 seismographs temporarily on and around Asama volcano and the data was transmitted to the Volcano Research Center, Earthquake Research Institute, University of Tokyo, by satellite, and cable telemetry systems. The Volcano Research Center further collected 6171 seismic data of permanent stations around Asama volcano operated by related research institutions, picking initial P- and S-wave phases manually. All the data will be compiled and distributed to the cooperated research institutions.
