Computer system and method for determining the regional effects of seismic events

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for determining a regional impact of earthquake events.;SOLUTION: Geographical regions (3, 4, 5) are associated with reference measuring stations (31-33, 41-43, 51-53) located in the respective geographical regions. For each of the geographical regions, determined are regional earthquake indexes based on instrumental intensity values that are received from the region specific measuring stations, and indicate the local strength of seismic motion. Each of intensity values is weighted with a weighting factor assigned to the reference measuring station that has provided the intensity value. Associating only selected reference measuring stations with a geographical station and weighting the intensity values with station-specific weighting factors make it possible to select reference measuring stations and weighting factors according to the geographical distribution of replacement values and, thus, to provide earthquake indexes that correlate accurately with potential earthquake damages. Furthermore, it is possible to determine the impact of earthquake events on multiple geographical regions that are not necessarily adjacent.;COPYRIGHT: (C)2010,JPO&INPIT
