Tides as triggers of earthquakes in Hindu Kush II

Abstract

The intermediate-depth earthquakes (˜200 km) in Hindu Kush, Afghanistan were investigated to prove their origin by tides. An untraditional astronomical method has been used to prove how astronomical parameters influence triggering of earthquakes. In contrast to previous issues, where Moon hour angles were used, Moons declinations were used successfully to prove tidal origin of earthquakes. Maximum earthquakes have been recognized during minor lunar standstills, i.e.

“…(Most authors consider this plate incorrectly as stable). Westward movement of Eurasian plate is confirmed by back arc basins on its eastern side and almost everyday earthquakes in Hindu Kush(Ostřihanský 2022). Similarly enormous earthquakes are triggered in Anatolian Block owing to balance of pressure from North Anatolian Fault and African Plate, whose subduction zones, namely Cyprus subduction, brake and decelerate northward movement of Anatolian plate (see inset 2 of Fig.3.…”

“…I recommend to reader to study Appendix where formulas indicate values of tidal torques dependent on Moon and Sun declinations and Earth's rotation, which creates bulging facilitating action of torques. Author in many papers (Ostřihanský 1991(Ostřihanský , 1997(Ostřihanský , 2015(Ostřihanský , 2022 indicated the action of tides on plate movement and earthquakes triggering. Similarly, as variations of the Earth's rotation are caused by tides, they can be used as indicators of plates movement and earthquakes origin.…”
