We have developed and implemented a new grid-based earthquake analysis system that continuously monitors long-period seismic wavefield of 20–50 s recorded by broadband seismometers. The new analysis system automatically and simultaneously determine

On March 20, 2005, a large M JMA7.0 earthquake occurred in the offshore area, west of Fukuoka prefecture, northern Kyushu, Japan. A series of joint observations were carried out by teams from several universities in Japan with the aim of investigatin

On September 1, 2004, Mt. Asama in central Japan erupted for the first time in 21 years. Between this moderate eruption and mid-November of the same year, 4 additional moderate eruptions occurred. We installed 8 broadband seismic stations in addition

From June 26, 2000, an intensive earthquake swarm started under Miyake-jima Island, 180 km south off Japan. This swarm was closely related to the eruption of Miyake-jima Island, probably dominated by underground magmatic activity. The swarm spread to

The superfast-spreading portion of the East Pacific Rise at 17.5°S is a magmatically robust section of mid-ocean ridge. Plumes characterized by high volatile/metal ratios, which has been hypothesized to be indicative of recent magmatism, were found

In 1988 an extensive geophysical investigation was performed at the middle Ryukyu island arc, S. Japan. An aim of the investigation is to obtain a detailed crustal structure at the trench-arc-back-arc system by various geophysical surveys. In this pa

The distribution and elemental composition of hydrothermal plume particles were mapped along the superfast spreading southern East Pacific Rise from the Garret Transform Fault to ∼19°S. Hydrographic and optical data were obtained using a series of

A disastrous earthquake with a magnitude of 7.2 hit the southern part of Hyogo Prefecture on January 17, 1995. The mainshock was located on an active fault of the Arima-Takatsuki-Rokko fault system. Its focal mechanism was consistent with a right-lat

A survey of hydrothermal activity along the superfast-spreading (approximately 150 millimeters per year) East Pacific Rise shows that hydrothermal plumes overlay approximately 60 percent of the ridge crest between 13°509 and 18°409S, a plume abunda
