Mega-tsunami for New York will be 400 meters; then engulfed-in-lava Los Angeles will be flooded too; also, asteroid destroys Gulf of Mexico; only Alaska, Eurasia, and Africa remain (obviously without coasts). 1st big earthquake in Russia; 2nd bigger one in China (will be split in half; radiation!); 3rd biggest will be in the USA (Greek Orthodox monk Elidiy from Africa); forgive me.
