Displacement analysis of aftershocks occurred after 6 February 2023 Kahramanmaraş Earthquakes

Abstract

The phenomenon of shaking the environments through which the shakings that occur due to
the fractures in the earth's crust spread as waves and pass through is called an earthquake.
Shakings that occur during an earthquake cause displacement in their locations. Many remote
sensing methods are applied to detect deformations. Turkey is located on the North Anatolian
Fault Line, the West Anatolian Fault Line and the East Anatolian Fault Line, and these fault
lines cause earthquakes from the past to the present. On February 6, 2023, 7.7 (Pazarcık) and
7.6 (Elbistan) earthquakes occurred in Kahramanmaraş. After these earthquakes, there were
many aftershocks. In this study, in which aftershocks were examined with PSI and SBAS
methods, the data obtained from the Sentinel-1 satellite was used.
