Abstract
One of the developing areas in Bengkuku City, Indonesia is the downstream of Muara Bangkahulu River. Therefore, this study aims to present an investigation of the local site and analysis of ground response in this area. Geophysical measurements were adopted in this research using multichannel analysis of surface wave and microtremor. Furthermore, field measurements were processed to interpret the characteristics of the ground surface, such as shear wave velocity (Vs) profiles, time-averaged shear wave velocity for the first 30 m depth (Vs30), and site classifications. The results show that the study area is categorised into Site Classes C and D. Also, the loose sedimentary soils exist at shallow depth and tend to be more vulnerable to undergo seismic phenomenon, which includes liquefaction and ground amplification. Generally, the results are expected to provide a better understanding of geophysical characteristics and earthquakes, which will help the local government to compose a spatial plan on the basis of seismic hazard mitigation.
