Review of Zoning Regulations for Seismic Area on the Southwest Coast of Sumatra, Indonesia

Abstract

Regional Indonesia is one of the countries with high seismicity as it is located in the Ring of Fire. This article describes and analyzes the regulations concerning the earthquake- prone areas on the southwest coast of Sumatera Island, particularly in Bengkulu. Earthquake and disaster-related data are taken using the library method from several previous research results anddisaster reports from government agencies. The research result shows that medium-risk earthquake hazards dominate Bengkulu City. Several policies and regulations concerning urban land use are issued, but they must be further harmonized with earthquake disaster mitigation objectives. Almost all areas are located in the moderate seismic hazard area, so general rules and parameters are required for the classification structure; this is a must toensure that in case of earthquake, human lives are protected. Detailed spatial plans and zoning regulations become essential documents that can regulate spatial use in detail, accompanied by calculations related to the density and environmental conditions of the area given the spatial provisions.
