Earthquake and Tsunami Threat in Lombok

Abstract

Lombok, the alternative tourism destination beside Bali, has beautiful sight and culture, but it also includes the vulnerability area in Indonesia. There are subduction zone and the Flores Fault in the south and north of Lombok. Both of them are a source of the earthquake. Based on the BMKG historical disaster, in 1992, there was an earthquake and tsunami comes from Flores Fault. In 2018, there was an earthquake coming from the Flores Fault. The earthquake is unique; it started from foreshock and followed by mainshock seven days later. It rarely happened in Indonesia. However, it is a difficult way to predict the earthquake is include in foreshock or not. Besides that, the tsunami potential that can occur from Flores Fault activity still become a mystery to some geoscientist.
