Abstract : North Bengkulu district is one of the districts in the province of Bengkulu, which is located adjacent to the Indian Ocean. This location is also nigh to the active tectonic plate subduction between the Indian-Australian and Eursia,. Earthquakes which occurred in the Bengkulu province from 1994 to now has led to extreme shoreline changes. These changes are predicted because the coastal in North Bengkulu district has a relatively low seismic vulnerability index and are in areas prone to earthquake. This research aimed (1) knowing the speed of abrasion in some locations that cause changes in the shoreline, (2) know the Seismic Vulnerability Index at several locations in the coastal region of North Bengkulu. Microtremor data at several coastal locations are acquired using a digital seismograph short periode 3 component. HVSR method give dominant frequency(fo) and the amplification factor (A) at each site and they were reviewed. Using the value of fo and A, can be calculated the value of the seismic vulnerability index (Kg). Abrasion speed can be calculated by means of overly between North Bengkulu map printed in 1994 to 2012. Seismic vulnerability Index in several locations are measured has a value that varies between 1.2 to 16.1 and speed abrasion between 1.4 to 5.7 meter per year. In coastal locations which have high seismic vulnerability index value tended to have high values of speed abrasion and vice versa.
