“…The decreasing SST trend could be caused by vertical mixed sea water column (Subrahmanyam, 2015). Earthquake vibration including foreshock, mainshock and aftershock triggered surface water to move down into subsurface water column, while subsurface water was forced to move up onto surface (Kopnichev & Sokolova, 2018;Zhigalin et al, 2014) Warm surface water heated by sun radiation moved down and it changed subsurface water temperature (Rogachev et al, 2000). Cold subsurface water moved up and it decreased surface water temperature.…”
