SEISMIC WAVEFORM ESTIMATION AT DAMAGE SITES OF KINOURA TUNNEL AND SUZU-HACHIMAN SHRINE, SUZU CITY, JAPAN, DURING THE 1993 OFF NOTO PENINSULA EARTHQUAKE BASED ON THE PSEUDO POINT-SOURCE MODEL

Abstract

 Serious failure of Kinoura Tunnel and collapse of Suzu-Hachiman Shrine was occurred in Suzu City, Japan, during the 1993 Off Noto Peninsula Earthquake. In this study, first, microtremor measurements were carried out in the damage sites of interest and the surrounding station sites. The pseudo point-source model for the 1993 main shock was then constructed based on the similarity between the observed and the synthetic ground motions at JMA Wajima. Finally, based on the results of the measurement and construction, ground motions at damage sites of interest during the 1993 main shock were estimated.
