| Abstract: | Microtremor observation was carried out in an active explosion crater of Shiretoko-Iozan volcano. Velocity seismograms indicated amplitude of microtremor was to be around 10-6m/s. Comparison with the 1981 observation showed no significant change of microtremor amplitude. This result suggested that activity status of this crater had been stable. Microtremor amplitude at the mountain base showed one fifth of that in the crater. This fact implied that microtremor is due to geothermal activity in the crater. |
