SUBMARINE TSUNAMI METER SYSTEM, SUBMARINE TSUNAMI METER DEVICE AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a submarine tsunami meter system, a submarine tsunami meter device and a method for providing a pure tsunami signal, by separating the change of the sea level (the tsunami signal) from the change of water pressure caused by crustal fluctuations.;SOLUTION: This submarine tsunami meter device 1 comprises a water pressure sensor 4 for continuously measuring water pressure, a displacement- measuring sensor 5 for continuously measuring crustal displacement at the sea bottom, and a signal transmission means 3 for sending data measured by the water pressure sensor 4 and the displacement measuring sensor 5, as signals to a transmission path 6. The displacement measuring sensor 5 and the signal transmission means 3 are provided inside a water pressure-proofing vessel 2 having sufficient strength to resist water pressure at the sea bottom. The displacement measured by the displacement measuring sensor 5 is converted into data of water pressure unit, and the data converted into water pressure dimension is subtracted from the water pressure measured by the water pressure sensor 4 for measuring pure height to the sea surface.;COPYRIGHT: (C)2001,JPO
