Comparative multifractal study of seismicity in two seismic zones of Türkiye in the period from 2010 to 2024.

Intense earthquakes have been natural phenomena that produce enormous disasters, mainly in large urban areas, due to the intense energy released in a very short period. Earthquakes are inevitable natural phenomena, and up to now, they cannot be predicted. On February 6, 2023, a M 7.8 earthquake occurred in southern Türkiye, near the northern border of Syria. This earthquake was followed by a M 7.5 earthquake to the north. The relative motions of three major tectonic plates (Arabian, Eurasian, and African) and one smaller tectonic block (Anatolian) are responsible for the seismicity in Türkiye. Recently, Onur investigated the aftershock distribution and its relation to energy release on the faults and Coulomb stress change areas, his study allowed the relocation of two-catastrophic earthquakes. In the present work we analyze the behavior of multifractality and its complexity parameters calculated from the catalog of seismic magnitudes during a period of 14 years monitored within two regions of Türkiye: the first one (west) between (35-42) Latitude, (25-34) Longitude and the second one (East) between (35-42) Latitude and (34-42) Longitude, being this area where the doublet occurred. Our results show differences in both multifractality and its complexity measures between the two regions. These findings may be indicators of expected seismicity in each region.
