摘要

2006年4月，在相模湾初岛附近的海底深处，一个电缆观测站探测到与5.5级地震有关的泥流。观察到与泥石流有关的环境波动。ADCP观测到海底12m以上的水流最大为27 cm/s，视频图像识别出几毫米的沉积。海底电缆两端电位差的波动表明，天文台西面斜坡的泥石流引起了海底电缆的运动感应。

Earthquake Accompanied by Mudflow Observed by a Cabled Observatory off Hatsushima Island in Sagami Bay in April 2006

Mudflow associated with an earthquake of magnitude 5.5 was detected with a cabled observatory on deep seafloor off Hatsushima Island in Sagami Bay in April 2006. Environmental fluctuations associated with the mudflow were observed. Water current 12m above the seafloor observed by ADCP was 27 cm/s at maximum and several millimeter sedimentation was recognized by video images. The fluctuation of electric potential difference between submarine cable ends indicates motional induction caused by the mudflow on the slope west of the observatory.
