Precursors of Pazarcik and Elbistan earthquakes 2023

Abstract

The paper explains origin of Pazarcik-Elbistan earthquake 2023 and seeks for precursors which could be helpful for earthquake prediction. Detailed tectonic study and correct direction of plates movement by tides revealed that the extreme quick Earth's rotation speed, after last 60 years, triggered this earthquake. Group of 5 low magnitude earthquakes before Pazarcik-Elbistan 2023 and 2 before Elazig 2020 earthquakes can be used as indicator preceding large earthquake. Maximum Moon and Sun declinations and coincidence with Full Moon indicated large tidal torques responsible for earthquake triggering. Nevertheless, there is following consequence: maximum Moon declination, Full or New Moon and then earthquake. Similar consequence has low magnitude precursors, occurring 2 or 3 days after ±minimum time deviation from 86400 s day standard.
