EARTHQUAKE MOTION DURATION TIME PREDICTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an earthquake motion duration time prediction system capable of predicting an earthquake motion duration time on an optional location at which earthquake motion observation data is not recorded.;SOLUTION: An earthquake motion duration time prediction system 1 includes a storage part 5 for storing the coordinates of a target location and ground conditions of the target location, a regression expression calculation part 41 for preliminarily modeling aging characteristics of waveforms of a plurality of pieces of observation data of actual earthquake motion with an envelope function and representing an earthquake motion duration time by a regression expression calculated with a hypocentral distance and Meteorological Agency magnitude as parameters, a reception part 2 for receiving real-time earthquake information including the earthquake location and Meteorological Agency magnitude, a hypocentral distance calculation part 42 for calculating a hypocentral distance on the basis of the earthquake location of the real-time earthquake information and the stored coordinates of the target location, and a duration time calculation part 44 for substituting the ground conditions of the target location, the hypocentral distance, and the Meteorological Agency magnitude for the stored regression expression, and calculating an earthquake motion duration time.;COPYRIGHT: (C)2013,JPO&INPIT
