Has there ever been a 10.0 earthquake?
No magnitude 10 earthquake has ever been observed. The most powerful quake ever recorded was a magnitude 9.5 temblor in Chile in 1960. A magnitude 10 quake would likely cause ground motions for up to an hour, with tsunami hitting while the shaking was still going on, according to the research.
