Analysis of Characteristics of Earthquake Area in Indonesia in 2020 with Cluster Analysis as Natural Disaster

Bambang Avip Priatna Martadiputra, Dewi Rachmatin, Asep Syarif Hidayat

This study aims to make maps and analyze the characteristics of earthquake areas in Indonesia in 2020. This study includes applied study in the field of statistics which applies cluster analysis to make maps and analyze the characteristics of earthquake areas in Indonesia in 2020. Making maps of earthquake areas is carried out with ArcGIS software help, while the analysis of characteristics of earthquake area is carried out using cluster analysis (k-medoids method) with R software help. The results show that during 2020, almost all areas in the Indonesian Archipelago are prone to earthquakes, except for areas in Kalimantan Island that are relatively safe from earthquakes. Most of the earthquake spots come from Maluku, Sulawesi, and Papua islands. The 2020 earthquakes are grouped into 9 clusters. The first, second, third, fourth, fifth, sixth, and seventh clusters are shallow earthquakes seen from the median depth of the earthquake which is less than 70 km. The eighth cluster includes intermediate earthquakes seen from the median depth of the earthquake reaching 143 km, while the ninth cluster includes deep earthquakes seen from the median depth of the earthquake reaching 631 km. This means that shallow earthquakes still dominate in 2020. The earthquake area which is included in the third cluster is an area that needs to be watched out for the frequency of the earthquake is higher than other areas.

Keywords: cluster analysis, k-medoids method
