Geophysical observation to several sites around Pulau Baai Port, Bengkulu city, Indonesia

Pulau Baai Port is known as the important area in Bengkulu City. The port also main that supports economic aspect Province. This study conducted to observe local site conditions several areas around Port. are very supporting function of Therefore, understanding surrounding regions needed. was initiated by performing a geophysical measurement using multichannel analysis surface waves (MASW) method. Measurements were performed 24 geophone channels obtain waves. Data processing plotting phase velocity corresponding frequency. Furthermore, shear wave (Vs) profile and time-average for first 30 m depth (Vs30) presented. Vs30 from measurements compared United States Geological Survey (USGS). In general, investigated sites categorized Site Class D. It indicates more vulnerable undergo seismic damage. results show relatively consistent with USGS. Generally, this could bring recommendation government considering hazard impact development.
