Cloud to Ground Lightning Strike Density Analysis Based on Geographic Information System in Tuban Regency Area

Abstract

Abstract This study aims to analyze the density of Cloud to Ground lightning strikes in the Tuban Regency area from September 2022 to January 2023 using the help of a Geographic Information System (GIS). After processing and analyzing the data, the results were that the highest lightning strike density occurred in October 2022, with 40240 strikes, while the lowest occurred in 2790 strikes. The total number of strikes from September to January is 135249 strikes. Based on aspects of the earth’s surface, it was obtained that the density of cloud to ground lightning strikes that occurred in the Tuban Regency area increased along with increasing height. This can be seen where the southern part of Tuban Regency, namely in the sub-districts bordering Bojonegoro Regency, including Parengan, Soko, and Senori sub-districts, has the highest level of vulnerability.
