Abstract

West Sumatra is an earthquake-prone area because it is located on the India-Australia tectonic plate with the Eurasian plate, the Mentawai Fault System (MFS) and the Sumatra Fault System (SFS) or the Sumatran fault. Therefore, there is a need for seismic studies to describe seismic characteristics. The aim of this research is to obtain the characteristics of the West Sumatra earthquake through Space-Time-Depth-Magnitude. The research flow consists of 7 stages, namely, data mining, data preprocessing, calculating the b value in the Gutenberg Ritcher equation, fractals, haversine distance, STDM, interpretation of results. The data used is data on earthquake events for the period 2009 to 2023 sourced from the Meteorology, Geophysics and Climatology Agency (BMKG) by dividing it into 3 periods, namely period 1 on 30 September 2009 to 24 October 2010, period 2 on 25 October 2010 to 10 April 2012 , period 3 from 11 April 2012 to 24 April 2023. The results obtained are that a decrease in the STDM distance in a period indicates that the destructive earthquake that will occur will have a smaller strength than the previous earthquake, while an increase in the STDM indicates that the destructive earthquake that will occur will have a greater strength than previous damaging earthquakes. It is hoped that the research results can contribute to describing the seismic conditions of West Sumatra so that casualties can be anticipated.
