The destruction in South America will be massive, if this is any indication: The Navy is evacuating parts Pearl Harbor, Hawaii, nearly 7000 miles away. Tsunami warnings are in effect as far away as Australia – almost 9000 miles away.
That’s the equivalent of 15.8 gigatons of TNT energy.
The mind reels.
Update: The most powerful earthquake recorded by man was also in Chile, in 1960. It measured 9.2 on the Richter Scale.
The event occurred at 0334 local time, 0634 UTC.
