Title:
Earthquake warning system
Document Type and Number:
Japanese Patent JP6358923
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an earthquake alarm system capable of distributing an earthquake alarm in a standpoint considering safety.SOLUTION: An earthquake alarm system 300 comprises: a data processing part for dividing an area to be an object of an alarm into plural areas, then arranging one or more observation points on each of the areas, and performing data processing based on an area earthquake motion index which is calculated by a reception part 201; and an earthquake alarm processing device 200 having a distribution part for outputting an alarm according to a processing result of the data processing part. The earthquake alarm processing device 200 outputs a first kind of alarm to each area whose earthquake motion index exceeds a first threshold when it is determined that there are areas whose earthquake motion index exceeds the first threshold, outputs a second kind of alarm to each area whose earthquake motion index exceeds a second threshold when it is determined that there are areas whose earthquake motion index exceeds the second threshold lower than the first threshold, and then outputs a third kind of alarm to each area adjacent to the area whose earthquake motion index exceeds the first threshold, on the basis of adjacent area data stored in a storage part 202.SELECTED DRAWING: Figure 1
