Abstract

The Aira caldera, located in southern Kyushu, Japan, originally formed 100 ka, and its current shape reflects the more recent 30 ka caldera-forming eruptions (hereafter, called the AT eruptions). This study aimed to delineate the detaile...

Tilt Observations at the Seafloor by Mobile Ocean Bottom Seismometers

Hajime Shiobara Aki Ito Hiroko Sugioka Masanao Shinohara Toshinori Sato

FRONTIERS IN EARTH SCIENCE 8 Mar 2021 [Refereed]

We have developed a broadband ocean bottom seismometer (BBOBS) and its new generation (BBOBS-NX) with the penetrator sensor system since 1999. With them, we performed many practical observations to create a new research category of ocean bottom br...

Stress loading and the occurrence of normal-type earthquakes under Boso Peninsula, Japan

Akinori Hashima Hiroshi Sato Toshinori Sato

Earth, Planets and Space 72(1) Jun 2020 [Refereed]

Boso Peninsula, Japan, was formed by the interaction of the Philippine Sea, Eurasian and Pacific plates around the trench-trench-trench Boso triple junction. Normal-type earthquakes are persistently observed in the subducting Philippine Sea slab u...
