抄録
Kuchi-no-Erabu-Jima is an active volcano island, which belongs to Kirishima volca-mc belt in Sonthern Kyushu.To obtain the foundamental geophysical data for this active volcano island, thefirst seismic observation and geomagnetic survey were carried out for about three weeksin Aug. 1966.On the 22th of Nov. 1966, the volcanic eruption happened at the top of Shindakein this island. Then, the same observation and survey were repeated from Nov. to Dec.1966, in order to examine the variations of geomagnetic anormaly and of the seismicitiesbefore and after the eruption.The main results are as follows.1. The significant difference between the results of the first and the second geomag-netic surveys could not be found out at all measured points except near the crater, where a great deal of volcanic ejecta was newly deposited.2. B-type earthquakes, which were not detected in the first observation at all, werefairy observed after eruption. It was confirmed by the tripatite seismic observation thatthese earthquakes originated around Shindake crater.
