The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (M w) that can exceed 9.0. [1] [2] Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. [3]
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.

Submarine earthquake, an earthquake that occurs underwater at the bottom of a body of water, especially an ocean. [17] Supershear earthquake, an earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity, causing an effect analogous to a sonic boom. [18]
The massive Dec. 26, 2004, tsunami was triggered by a magnitude 9.1 earthquake off Sumatra island. The giant wall of water killed about 230,000 people in a dozen countries as far away as East Africa.

In 2011, more than 18,000 people lost their lives amid a magnitude-9.0 earthquake and tsunami in Tohoku, Japan, The New Yorker noted. That catastrophe wound up costing approximately $220 billion.
