APPLYING K-MEANS ALGORITHM FOR CLUSTERING ANALYSIS EARTHQUAKES DATA IN WEST NUSA TENGGARA PROVINCE

This study aims to cluster and visualize the earthquake data on a geographical map determine earthquakes' characteristics using k-means algorithm. Cluster analysis algorithm was carried out data. K-means is familiar one of well-known techniques have been applied in analysis. One Its advantages scaling large datasets, for example, The used this West Nusa Tenggara from 1991 2021. Applying proposed algorithm, optimal number clusters (k) clustering 2, based highest silhouette score 0.749. showed that epicenters earthquakes were pretty spread before 2018, eastern region more than western area. However, all bunched northern Lombok region. There few west but they happened August 5. Even after 2019, most continue occur, with clustered close
