Daftar Isi:
- This research aims to study the characteristics of shore type with the variety of geological conditions, based on the Ground-Shear Strain (GSS) as an indicator of the rate of abrasion at the west coast of Bengkulu province, Indonesia. At each shore type, the ground motions was acquired using short period seismograph. The ratio of the horizontal to vertical spectral value (HVSR) produced the dominant frequency (fo) and peak amplitude of HVSR spectrum (A). Thus, the value of the seismic vulnerability index (Kg) can be calculated using empirical formula. The Ground-Shear Strain (GSS) was obtained by multiplying the Seismic Vulneribility Index (Kg) with Peak Ground Acceleration (α), where α is calculated by using the Kanai empirical attenuation reletionship.The results show that the GSS value at the western coast of Bengkulu province are characterized into eight types of shore, with the values ranging from GSS 1.6 x 10-4 - 78.3 x 10-4
