Abstract

This research characterises shore types on the west coast of Indonesia’s Bengkulu province based on a variety of geological conditions, especially the ground shear strain, which serves as an indicator of the rate of abrasion. For each shore type, the ground motions were measured using a short period seismograph. The ratio of the horizontal to vertical spectral values (HVSR) provided the dominant frequency ( Fo) and peak amplitude of the HVSR spectrum (A). The value of the seismic vulnerability index (Kg) could then be calculated using an empirical formula. The ground shear strain was obtained by multiplying the Seismic Vulnerability Index (Kg) by Peak Ground Acceleration (α) using the Kanai’s empirical attenuation relationship. The results show that the ground shear strain values on the western coast of Bengkulu province are characteristic of eight different types of coastline, with the GSS values ranging from 1.6 x 10-4 to 78.3 x 10-4
