SEISMIC INTENSITY ESTIMATION DEVICE, SEISMIC INTENSITY ESTIMATION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A seismic intensity estimation device (10) is provided with: a seismic source determination unit (11) which, when seismographs (20) installed in respective regions along the boundary of a continental plate output data by which the amplitude of a seismic wave can be specified, determines whether the position of a seismic source is within a set region; an adjacent area specification unit (12) which, when the position of the seismic source is within the set region, specifies an adjacent area adjacent to an area where the seismograph that detected the seismic wave first is installed; an attenuation determination unit (13) which acquires data from the seismograph in the adjacent area and determines whether attenuation is occurring in the amplitude of the data; a fault rupture point setting unit (14) which, when the attenuation does not occur, sets a fault rupture estimation point on the set region on the basis of the position of the adjacent area; and an estimated seismic intensity calculation unit (15) which calculates an estimated seismic intensity with the fault rupture estimation point as the center.
