Analysis of the behavior of tectonic earthquake 2018 in Lombok Island using the descriptive statistics approach

Abstract

The Indonesian territory is at the confluence of the Indo-Australian, Pacific, and Eurasian tectonic plates so that the Indonesian territory is categorized as an earthquake-prone area. Lombok Island is a part of the Indonesian territory, so it is also an earthquake-prone area. The tectonic earthquake in 2018 (end of July-August 2018) which caused many casualties and property as evidence that Lombok Island is an earthquake-prone area. In this research, a descriptive statistical approach will be carried out related to the behavior of tectonic earthquakes in 2018, especially in July-September 2018 on the island of Lombok. The behavior analyzed was related to the epicenter earthquake distribution and at certain depth intervals by hypocenter. In addition, it also analyzes the symmetry of the data distribution. The results of this study are expected to provide significant input for district/city governments on the Island of Lombok and also the government of West Nusa Tenggara Province.
