FYI,
No earthquake with a magnitude of 10 or higher has ever been recorded in history. The largest earthquake recorded was the Valdivia earthquake in Chile on May 22, 1960, with a magnitude of 9.5. Other significant earthquakes include the 1964 Alaska earthquake (9.2) and the 2004 Indian Ocean earthquake (9.1) 

A magnitude 10 earthquake is theoretically possible but has never happened! It would require a massive fault rupture, lasting up to 30 minutes, and could cause unimaginable destruction and tsunamis.
