Abstract

The devastating earthquakes with moment magnitudes of 7.7 and 7.6 occurred in Pazarcık and Elbistan districts of Kahramanmaraş on February 06, 2023 according to the data of the Earthquake Department of Disaster and Emergency Management (AFAD). The loss of life in these earthquakes exceeded 50,000 people and eleven provinces suffered loss of life and property. After these earthquakes, seismic activity increased in some regions and even some damaging triggering earthquakes occurred. An earthquake with a magnitude of Mw 6.4 occurred in Hatay province, located southwest of the 2023 Kahramanmaraş earthquakes on February 21, 2023, while seismic activity increased unusually in the northeastern part of the 2023 Kahramanmaraş earthquakes. The 2023 Kahramanmaraş earthquakes ruptured about 400 km of the Eastern Anatolian Fault Zone and changed the stress conditions in the region. Earthquake activity also increased in and around Erzurum province after February 6, 2023. Lastly, on 13.04.2023, more than 10 earthquakes, the largest of which was 3.9, occurred in Aziziye district of Erzurum province as of 00:00 on 14.04.2023. Since these earthquakes occurred in the residential areas of the city, they caused an echo in the city. At the same time, the citizens living in this region felt the earthquake more intensely due to the high liquefaction potential of Aziziye district related to the fact that the underground water level is very close to the surface of the surface and the soil bearing strength is low due to the thick alluvium. In this study, a series of statistical analysis on Aziziye earthquakes were conducted. At the same time, the damaged buildings in Söğütlü village of Aziziye district, the epicenter of the earthquake, were examined.
