Estimation of Ground Motion Distribution Utilizing Strong Motion Record Offered on the Internet

Abstract

In recent years, after an earthquake, strong motion records are offered on many internet sites. This paper constructs the computer system which estimates the ground motion distribution utilizing these records. Because this makes estimated distribution of ground motion closer to real distribution, it can be expected to improve the precision of damage estimation. This paper also presents the estimation method to avoid influence of vacancy of observation near epicenter and to shorten calculation time of spatial interpolation.
