Abstract

Determination of the epicenter point (the epicenter point recorded on the earth's surface) and the hypocenter (the epicenter point recorded below the earth's surface) earthquakes can be done with numerical calculations. This study determined the epicenter and hypocenter point of the earthquake that occurred in Antelope Valley, California, United States in 2021 with a magnitude 6.0 at geographic latitude 38.507oNL and longitude 119.499oWL. The quake was recorded at three nearby stations, NV31, PASC, and CMB. The estimated point of the earthquake is in the middle of the three stations, so earthquake recording data at all three stations is very important because it is considered the most accurate. The study used Grid Search by plotting 2D and 3D method. Data processing using Google Collaboratory, and SeisGram2K v7. The calculation data refers to official information from the USGS (United States Geological Survey) website. Based on calculation, obtained the result of plotting 2D that the epicenter points at latitude 39,255⁰ NL and longitude 119.833⁰ WL. The results of 3D plotting show the hypocenter point at latitude 38,627⁰ NL, longitude 119,788⁰ WL, with a depth of 18 Km
