Abstract

Pasuruan is an area prone to lightning strikes because it is high ground between mountains and the sea, the Cumoonimbus cloud easily formed, which created lightning. Lightning in great quantity is a factor that affect the vulnerability levels of regions rate against lightning strikes, in additional to potential casualties or losses inflicted such as how populous the population or the level of buildings in the region hs also cused an area to be vulnerable to lightning strikes. The purpose of this reserach is to analyze the level of threat, susceptibility, and vulnerability of lightning strikes in the Pasuruan district. On the vulnerability levels of lightning strikes was affected by two factors, the threat factor is using data genesis lightning CG and the vulnerabilities factor is using data population density and land density for home and buildings. The method uses to analyze the two factors in this research uses Simple Additive Weighting (SAW) method to get the vulnerability levels of lightning strikes for every sub-district in the Pasuruan district those depicted on the map using ArcGIS 10 software. The result of the research showed that Puspo, Lumbang, Pasrepan, Purwosari, Pandaan, Gempol, Bangil, Rembang, Pohnjentrek Gondangwetan, Rejoso, Winongan, Grati, Lekok dan Nguling were areas which potentially had a very high level of troubled of thunderbolt.
