An active seismic survey with unprecedented density of seismometers found a high velocity zone to the west of the summit of Asama Volcano, Japan. The high velocity zone coincides with an area of magma-filled crack (dike) intrusion associated with the

In Japan, 47 among 110 active volcanoes are monitored by the Japan Meteorological Agency on a 24-h basis, and several universities develop volcanological studies with their own volcano observatories at some of the recently active volcanoes. Some othe

Since the caldera-forming eruption of Miyakejima Volcano in 2000, low-frequency (LF) earthquakes have occurred frequently beneath the caldera. Some of these LF earthquakes are accompanied by emergent infrasonic pulses that start with dilatational pha

We deployed a network of broadband seismometers for one year around the Naka-dake first crater of Aso volcano in Kyushu, Japan, to reveal the mechanism of long period tremors (LPTs) emitted from the volcano. It is observed that LPTs with a dominant p

At Unzen volcano, rainfall caused lava dome collapses and pyroclastic flow in some cases. Heavier precipitation increases the probability of dome collapses and pyroclastic flows, and increased pyroclastic flows are correlated with precipitation for c
