Abstract

The earthquake is one of the natural disasters that is destructive and claimed lives at a certain magnitude and depth. Indonesia is an earthquake-prone area because it is in the area of major tectonic plates. Province of Nusa Tenggara Barat is one of the 34 provinces in Indonesia which is earthquake prone. In this research, earthquake grouping will be carried out in the Province of Nusa Tenggara Barat using the K-Means cluster approach. Furthermore, using the Kolmogorov-Smirnov test the type of distribution is determined for each group variable resulting from the cluster process. The data used was the 2018 earthquake data in West Nusa Tenggara Province, sourced from the USGS earthquake catalog. The software used in this research process is SPSS, GMT, and Matlab, respectively. The results of this study are expected to be used as a reference for the Government of Nusa Tenggara Barat Province and surrounding areas related to earthquake disaster mitigation, especially evaluation of spatial and regional.
