The investigation of megathrust zone in the southern part of West Nusa Tenggara island using gravitational data and power spectrum analysis.

Lombok is one of the islands that has a very high level of vulnerability to geological disasters. In 2018 there was an earthquake that caught the attention of the government and researchers. The earthquake occurred for two months, namely July to August. The studies conducted on the Lombok earthquake in 2018 still do not describe the characteristics of the source in a comprehensive and detailed manner. So it is hoped that this study can reconstruct the main earthquake source model that occurred. The method used in this study is the gravity method. This study aims to produce a good understanding and knowledge of the characteristics of geological hazard sources on the island of Lombok. [ABSTRACT FROM AUTHOR]
