MEASUREMENT OF SHEAR STRAIN IN MAP LIQUEFACTION AREA FOR EARTHQUAKE MITIGATION IN BENGKULU CITY.
TELKOMNIKA, 16 (4).
Bengkulu city is well-known as a high-risk area for the earthquake. One of the effects of earthquake is the strength and stability of the soil is reduced by shock. These values can be obtained from the United States Geological Survey (USGS). In this study, however, we measured liquefaction based on the shear strain value (γ). Here, the shear strain values could be determined by measuring the seismic vulnerability index and the peak ground acceleration. The vulnerability index was obtained by measuring the resonance of the frequency and amplification factor seismometer with 3 components (2 horizontal components and 1 vertical component), while the data is occurring in Bengkulu City. in 2000. The results showed that Vs30 and shear strains were negatively correlated.
