dc.description.abstract | Bathymetric, seismic, geomagnetic and gravity survey around O-Sima volcano was carried out by the survey vessel Takuyo of the Hydrographic Department of Japan, after vast volcanic eruption of O-Sima volcano in 1986. The survey revealed that several geological and geophysical characteristics of the adjacent area of O-Sima Island are as follows: i ) NW-SE topographic and geomagnetic elongations due to underwater fissure eruptions were recognized in the area off Tigasaki, northwestern end of O-Sima Island and off Habu, southeastern end of O-Sima Island. ii) U-shaped bathymetric high adjacent to the west coast of O-Sima having high magnetic anomaly, or the Senba Spur, is considered to be an old volcano mass contiguous to O-Sima volcano. | en_US |
