A note of ground motion interpretation and site response analysis during the 2007 Bengkulu–Mentawai earthquakes, Indonesia

This paper presents the interpretation of ground motions and comparison site response analysis due to 2007 Bengkulu–Mentawai earthquakes in Mukomuko regency, Bengkulu Province, Indonesia. regency was reported as most impacted area during earthquakes. The recorded were analysed obtain motions. Furthermore, sites performed observe spectral acceleration. results showed that first aftershock tends have more played key role yielding damage regency. It shown by high level Modified Mercalli Intensity (MMI) motion parameters resulted aftershock. acceleration is critical at a short period. result also propagated seismic waves could amplify surface. In general, this study provide better understanding earthquake impact
