| Abstrak/Abstract |
-Due to the diversity of landform configuration in Wonosobo district consisted of several aspects
namely morphology, process, and material or lithology, this generates to different responds against
lightning strike vulnerability in Wonosobo district. This is proven by recent lightning strike accidents
threatening human safety besides subverting infrastructure and environment in just certain point
locations. Lightning strike occurrence in Wonosobo district so far provokes negative impacts
towards human, infrastructure, and environment. Accordingly, mapping on lightning strike
vulnerability is consequential to be undertaken in order to minimize negative impacts by dint of
lightning strikes.
This research is intended to find lightning strike vulnerability zones out built upon landform condition
and find correlation out between lightning strike vulnerability and landforms. Lightning strike
mapping takes place in Wonosobo district, Central Java. The Data used are Cloud to Ground type
lightning strike data and annual thunder-day data in 2015 based on climatological data sets from
BMKG. The data are processed using Lightning Detector 2000 software and mapped using Arcgis
with Krigging method.
According to image interpretation, there are three geomorphological units in Wonosobo district
namely Volcanic, Structural, and Fluvial. Those three geomorphological units have differences in
terms of morphology, topography, and material. The results shows that the highest intensity of
lightning strike vulnerability occurs in volcanic geomorphological unit. This condition sprung by
topography and constituent material effects. A better development in disaster risk management
ought to be emphasized on volcanic geomorphological unit considering the potential of lightning
stike accident is still substantial. |
