Determination of the earthquake epicenter using the maximum displacement method obtained by Sentinel-1A/B data via ESA SNAP software

Year: 2022

Type: article

Abstract: This article discusses a method for determining an earthquake’s epicenter using modern radar data from the Sentinel-1A/b remote sensing satellite. To determine the epicenter of the earthquake, finding the maximum displacement from the radar image data was used. The displacement (displacement) of the earth’s crust was obtained by processing on the ESA SNAP software. Two earthquakes that occurred in 2020 were studied to determine the epicenters in the ascending and descending orbits of the satellite. These earthquakes occurred in Western Xizang, China, and Doganyol, Turkey. The maximum deviation from the epicenter’s officially registered coordinates was 15.6 km for Doganyol and 3.2 km for the West Xinjiang Earthquake.
