Abstract

Sumatera Island which is directly adjacent to Sunda Strait and traversed by ring of fire and still happens often natural disasters especially earthquakes. To reduce risk and impact from earthquake damage it is necessary to do earthquake disaster mitigation by using mapping the earthquake-prone areas in Bandar Lampung City. Mitigation done by measuring around the City of Bandar Lampung by using the active MASW seismic method. MASW method is useful to determine rock type and site class based on depth of shear wave velocity value from rock bedding which in the surface. This method process is firstly done by data acquisition in 24 measuring point scattered in Bandar Lampung City, then data processing is done from measured data geometry editting, then the data changed to velocity-frequency phase from time-distance domain. Velocity picking done to dispersion curve spectrum analysis to get dispersion curve value. Dispersion curve inverted, and acquired 1D shear wave velocity value profile to depth. Shear wave value obtained and generate site class, it will be useful to identify and map soil type and rock type on that area.
