Seismic activity increases

High seismicity was recorded on 14 July with a total of 14 earthquakes. The Nasu volcano group consists of a N-S cluster of stratovolcanoes and lava domes at the N end of the Kanto plain. Nasu volcanics date back at least 350,000 years. The youngest dome, Chausu-dake, is late Holocene in age and has had several severe explosive eruptions since its first historical eruption in the late 14th century.

Earthquake swarm with felt events

An earthquake swarm including felt shocks occurred on 30-31 January, but no surface phenomena were observed.

Information Contacts: JMA, Tokyo.

Two earthquake swarms

Local seismic activity increased 9-12 September at the N foot, about 10 km from the summit. Magnitude [3.5] events recorded on 9 and 11 September were felt at intensity I and II at a town 7 km NW of the summit, but were not felt at the JMA Nasudake Volcano Observatory, about 19 km to the SSE.

Another swarm of small earthquakes occurred [27-29 September] at the NE foot, about 10 km from the summit. Three larger events were felt at Kashi hot spring, 7 km NE of the summit, but again none were felt at the JMA Observatory. The JMA seismic network in this area could not accurately determine hypocenters and magnitudes of small events. The largest events of this swarm were estimated to be roughly magnitude 2.7. Earthquake swarms are common around Nasu.
