Subduction earthquake effect on lateral ground movement for offshore structure in Malaysia water

Peninsular Malaysia is located in a low seismic region. Although Malaysia is not located in an active fault seismic area, it is in the vicinity of the Sumatran and Philippines active seismic zones. Tall buildings frequently felt the tremor generated from Sumatran subduction and fault zones especiall...
