Outline of Final Research Achievements

A laboratory experiment using a pressure standard (i.e., a dead weight pressure calibrator) has been performed to investigate the in-situ response of bottom pressure recorders (BPRs) during an earthquake.
On November 16, 2017 at 09:43 UTC, an earthquake with a magnitude of 5.8 occurred off the east of Hachijo Island. In-situ recordings were obtained by BPRs and two kinds of seismometers of the DONET seafloor observatory in the Nankai Trough. We have carried out a laboratory experiment with three BPRs connected to the pressure standard during the earthquake, which provided the first opportunity to compare in-situ data with laboratory pressure measurements.
Various features of pressure fluctuation and ground motion were comparable between the laboratory experiment and the in-situ observation. The pressure fluctuation recorded by BPRs during an earthquake follows the acceleration that forces the water mass above the BPRs.

Academic Significance and Societal Importance of the Research Achievements

現在、日本の周辺海域には多数の水圧式津波計が展開されており、津波警報の更新や津波観測情報の発信等へ利用されている。水圧式津波計は津波観測の情報を沿岸到達前に取得できる手段として普及していることから、津波観測時には波高を正確に推定することが不可欠である。
本研究で得られた成果から、海底地震計を併用することで水圧式津波計のデータから地震発生時の水圧変動等を除去でき、津波波高を高精度に推定できることが見込まれる。したがって本研究で得られた知見は、海底圧力計のリアルタイムデータ利用の高度化に資するものである。
