The Bangkok Basin has been known from non-instrumental observations of the local population to be subject to ground motion amplification due to the deep alluvial sediments and basin geometry. The purpose of this study is to analyze a limited amount of seismic data to confirm that basin effects are significant in the Bangkok Basin. The paper contributes to the evaluation of basin effects by quantifying those effect albeit at very low ground motions. With this purpose, we analyze ground motion records from seismic stations located within the Bangkok alluvial basin from 2007 to 2021. Recorded pea Authors: Teraphan,,Ornthammarath.
