An earthquake can have a negative magnitude
Some of the most powerful known earthquakes in the continental U.S. occurred in Missouri between December 1811 & February 1812. Multiple quakes occurred with a magnitude of 7.5 or greater shaking an area ten times larger than that affected by the magnitude 7.8 San Francisco earthquake of 1906
8 months ago, the U.S. military and troops from 20 countries practiced responding to an 8.2 magnitude Earthquake- in Nepal.

Has australia experienced earthquakes where when magnitude devastation?

The presence of the asthenosphere was suspected as far back as 1926. It wasn"t confirmed until after the Great Chilean earthquake of 1960. The earthquake reached 9.5 on the moment magnitude scale. Analysis of the earthquake waves confirmed the presence of the asthenosphere.

How often do magnitude 9 earthquakes occur?
