Abstract

Some responses to the remote earthquakes can be possibly felt by people in Bangkok. It indicates that there is seismic wave amplification during the earthquakes. The geological condition and the vibration intensity of the ground are the main factors of the amplification. In this study, the site-specific investigation was conducted in Bangkok including the boring log and shear wave velocity measurement. Analysis of non-linear seismic wave propagation were performed for each studied site. Model of Next Generation Attenuation (NGA) is used to ground motion from the earthquake under the activity of Three Pagodas Fault on the eastern Thailand bordered with Myanmar. The input motions were obtained from the database of Pacific Earthquake Engineering Research (PEER). The key results of ground motion characteristic are reported in this study. In general, the results show the effect of the motion due to earthquake to Bangkok subsoil. The investigated sites could undergo amplification during the earthquake under the scenario of Three Pagodas Fault. The results also suggest the people to consider the earthquake impact which is possibly triggered by the activity of Three Pagodas Fault.
