An earthquake is not a warning from your God . Its natural disasters like tornados, tsunamis, Volcanoes e.t.c.
Also "Gods shooting" earthquakes because other people having fun drinking listening mucic too loud, i mean, think about it man.
I also believe in God existence (Not allah althought. Being a orthodox christian here.)
Religion teach us how to love other people and vice versa. I dont think they want us to have no fun e.t.c.
Anyway, Glad nothing bad happened to you and your family.
