Abstract It has been known that Bengkulu City (Indonesia) is vulnerable to undergo seismic damage. This study initiated by measuring horizontal vertical spectral ratio ( H/V ) sites in using microtremor. The inversion analysis performed generate shear wave velocity profile. Hundreds of are investigated this study. results show observed consistent with the theoretical . National Earthquake Hazar...
