Title:
Earthquake prediction device
Document Type and Number:
Japanese Patent JP6189923
Kind Code:
B2
Abstract:
An earthquake prediction device comprises a predicted value calculation unit 16 that calculates, from a prediction formula below, a predicted value (MMIap) indicating a predicted intensity of a ground motion on the Modified Mercalli Intensity scale, using a maximum acceleration value (Aumax), which is a maximum absolute value among absolute values of vertical acceleration component of the ground motion, after a sensor starts detecting the ground motion caused by an earthquake. The prediction formula is: MMIap=±alog 10 (Aumax)+²a
