2006 Kuril Islands earthquake and tsunami – magnitude 8.3 earthquake, no injuries or fatalities anywhere; 2009 Samoa earthquake and tsunami – magnitude 8.0 earthquake with an epicenter 120 miles (190 km) southwest of American Samoa generated tsunami waves up to 16 feet (5 m), killing 34 people in American Samoa and causing extensive damage [39]
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
Lasting four minutes and thirty-eight seconds, the magnitude 9.2–9.3 megathrust earthquake remains the most powerful earthquake ever recorded in North America, [2] [4] and the second most powerful earthquake ever recorded in the world since modern seismography began in 1900. [5]
That’s also where South Carolina’s most powerful recent earthquakes were recorded on June 29, 2022. On that day, two earthquakes — one a 3.5 magnitude and the other 3.6 — were included in ...

An earthquake shook off the Oregon coast Wednesday afternoon. The earthquake struck in the Pacific Ocean, more than 170 miles west of Bandon, Oregon at 1:15 p.m. local time, according to the U.S ...
Most studies have placed it at 9.4–9.6 on the moment magnitude scale, [1] while some studies have placed the magnitude lower than 9.4. [6] [7] This makes it the most powerful earthquake ever recorded. It occurred in the afternoon (19:11:14 GMT, 15:11:14 local time), and lasted 10 minutes.
Florida’s Atlantic coast experienced a rare earthquake overnight, measuing a seafloor-shaking 4.0 magnitude, according to the U.S. Geological Survey.. The quake occurred at 10:48 p.m. Wednesday ...
