The eathquake removal was unexpected for me, because there is a theory going around that at least 2 earthquakes, occurring on 9-Sep-2017 and 2017-Sep-21 which occurred after record setting rainfall in Texas from hurricanes Hurricanes Harvey Aug 2017 and Irma in Sep 2017.
A similar occurrence happened in Japan after Typhoon Jebi in Sept 2018, the earthquake was on Sept 5th 2018. My conjecture is that the trillions of gallons of water was enough weight to slightly depress the earths crust, causing the slippage between tectonic plates, which triggered the earthquakes.
