Title:
津波監視システム
Document Type and Number:
Japanese Patent JP5924469
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tsunami monitoring system which is excellent in economical efficiency of the installation of an observation apparatus and maintainability and facilitates observation and confirmation.SOLUTION: In a tsunami monitoring system, an observed sea surface is scanned with radar waves emitted from a radar installed on land at a predetermined cycle to perform the measurement of the observed sea surface by the reflection of the radar waves, the obtained data are processed to measure the elevation of the sea surface, and an alarm is raised when the rising of the sea surface exceeds a fixed value in the observational measurement. In the tsunami monitoring system, observational data of P-wave seismographs installed at plurality of points on land are collected in a server at the occurrence of an earthquake, a sea side earthquake source and the magnitude of the earthquake are calculated by the analysis of the P waves of the occurred earthquake, the possibility of the occurrence of tsunami and the magnitude of the tsunami are estimated, and when the possibility and magnitude of the tsunami exceed fixed values respectively, this result and the data of the tsunami monitoring system are comprehensively determined to issue a final evacuation warning.
