Abstract

Swarm earthquake in the Jailolo region based on data from the Geophysical Station BMKG Ternate in November 2015, there were 701 event earthquakes. Measurement of the value of physical vulnerability based on amplification factors produces a map of the physical vulnerability of an area by welding, which uses 3 classes, namely low, medium, and high. This information is used as a disaster mitigation effort and becomes a recommendation for regional development spatial planning and earthquake-resistant infrastructure in the Jailolo region. The method used is quantitative descriptive from microtremor data and physical vulnerability assessment. Microtremor measurements using a seismometer TDS-303 type. The physical vulnerability indicators used are the percentage of the built area, the number of buildings, the road network, and the Regulatory chief of BNPB 2012. The result is the level of physical vulnerability in Jailolo District by 28% of villages with a category of high physical vulnerability, the value of soil amplification (A0) in Jailolo District ranged from 4.67 – 50.98. So it can be concluded that the villages that are categorized as high physical vulnerability and high amplification value are the Acango Village with a physical vulnerability index value of 2.6 and an amplification value of 15.26.
