The mechanism of earthquake swarm that occurred at Mt. Yakedake on November 8, 1968, have been studied. The swarm began at Olh3Om and terminated at 14h51m. 43 shocks wererecorded at Kamitakara by the vertical component seismograph for the observation of micro-earthquakes. The frequency distribution of the P-IS interval times of the swarm corresponds toone of four peaks in that distribution which were observed at the station during four monthsbefore the occurrence of the earthquake swarm.The foci of these shocks have been determined from the P-IS times observed at the near micro-earthquake observation stations. They are confined within a small volume whose dimensionis about 500 meters.The time variation of the S/P which means the ratio of the maximum amplitudes of P and Swaves have been investigated. The push-pull distributions of the initial P motions have beenalso studied. The results show that the focal mechanism changes in relation to the activityof the earthquake swarm and seems to approach the stationary state at the end of the swarm.It is supposed that the occurrence of the main shocks disturbed the stress field around theirfoci and gave the great influences upon the mechanism of the smaller shocks.This earthquake swarm is separated into four sequences. In the first sequence the large shockof M=~3.4 occurred in isolation. The main shock of M=3.3 and many aftershocks took placein the second sequence, the main shock of M =03.1 with some foreshocks and aftershocks occurredin the third one and the swarm of some smaller shocks occurred in the fourth one. This variationof the characteristics of the activity of each sequence seems to be related to the development ofthe fractures in the focal region.

Earthquake swarm activities have been occurring since January 1990 in the vicinity of Mount Yake-dake volcano in central Honshu, Japan.The volcano erupted frequently but it has been 30years since the last eruption in 1962.Temporary observation of microerarthquakes was conducted -near the volcano to survey the seismic activity.A station was set at about 1.5 km away from the summit crater in September, 1990 and five temporary stations were installed in the surrounding area of the volcano during the period from July to September, 1992. After that, three stations have been maintained to monitor the seismic activity.Although only a few events were located in the volcano during the period from July to September, 1992, the focal depths of the events were found to be very shallow as less than 3 km.In October and December, earthquake swarms occurred right beneath Yake-dake volcano.Earthquake swarms were also found in northeast, north and southeast of the volcano.Reviews of the studies on the volcano activity and earthquake swarms near the volcano are also given in this paper.

We investigate the characteristics of great earthquakes occurring in the central Kuril Islands on 1915, 1918, 2006 and 2007. Comparisons of seismic intensity distributions, tsunami data and waveforms of above four events were made. Though magnitudes of these earthquakes were almost the same, only the 1915 event did not generate observable tsunami. This fact may be due to deep focal depth of this earthquake. Similarities of seismic intensity distributions between the 1915, 1971 and 2008 deep-focus earthquakes also imply that the 1915 event was the deep-focus event in the northeastern Okhotsk Sea. Waveform properties of the 1915 and 2008 events supports above hypothesis. We conclude, therefore, that the 1915 earthquake was not the event in the central Kuril Island but in the Okhotsk Sea with deep depth. Large tsunami and widespread felt area of the 1918 earthquake show that this event was a typical shallow-dipping thrust event on plate boundary as indicated by previous studies.

Since the 2011 Tohoku-oki megathrust earthquake, Japan, it has been recognized that there is a variety of megathrust earthquakes occurring in the world not just only the Chilean type megathrust earthquake. In the variation, one end member is the 1960 Chile earthquake and the other is the 2004 Sumatra-Andaman earthquake, while the former is characterized by subduction zone of a young plate forming the Cordilleran orogeny, the latter is by an obliquely subducting plate along a continental margin with active back-arc activity. We study in detail megathrust earthquakes along such oblique subduction zones, considering characteristics of earthquake activities, focal mechanisms, rupture patterns, geometry of subduction zones, types of overriding plates and back-arc activities. Discussions are further made on one of the oblique subduction zones near Japan Islands, the Sagami Trough, in order to derive some information and the possibility of future large earthquakes there from the seismological data at hand. We found that there is a variety of large earthquakes in the oblique subduction zones in the world. Since we have no hand to suspect the future activity of a particular subduction zone, comparative studies on seismic activities in different oblique subduction zones are inevitable.
