National Research Center for Disaster Prevention is conducting volcanological research on Iwo-jima and Kirishima volcanoes. In these volcanoes, various observations and investigations have been carried out and the relations between their volcanic activities and volcanic earthquakes, crustal movement, etc. have been studied aiming at the prediction of volcanic eruption. The data book includes following items expressed graphically : 1. On the Iwo-jima volcanoes (Motoyama and Suribachiyama volcano) (1) observational data of volcanic earthquakes (magnification is 10, 000 at 10Hz, observation term : 1983.7-1984.6) 1) daily number of volcanic earthquakes of Type A 2) mean daily number of Type A of volcanic earthquakes in each month (2) observational data of ground tilt (1983.7-1984.6) (3) observational data of fault movement (1983.7-1984.6) (4) observational data of fume temperature and temperature of ground (1983.7-1984.6) (5) observational data of sea level (1983.7-8, 1984.1-6) 2. On the Kirishima volcanoes (Ebino-Yoshimatsu District Earthquake Observatory) (1) observational data of ground tilt (1983.7-1984.6)
