William, would you kindly explain the strength of this quake by translating the energy as below: 336 Mega tons / 1,41 EJ (Sendai quake) One has to imagine the Sendai bay as a wonderful landscape with several volcanoes. I was there twice & enjoyed gorgeous food there. Toba volcano explosion 75.000 years ago on Sumatra is estimated at 84,4 Mega tons & 210PJ http://en.wikipedia.org/wiki/Richter_magnitude_scale ################################################################### Am 11.03.2011 um 13:57 schrieb [email protected]: > Japan is certainly no stranger to major Earthquakes, but this one is the > largest Japan or the surrounding area has ever recorded I think. > > The Northridge Quake, although 'only' at a 6.7, had one of the fastest > ground accelerations ever recorded - at 1.7 Gs. > > As you can see from here, quakes of magnitude 8.5 or higher are very rare > indeed: > _http://earthquake.usgs.gov/earthquakes/world/10_largest_world.php_ > (http://earthquake.usgs.gov/earthquakes/world/10_largest_world.php) > > -William > > > > In a message dated 3/11/2011 7:50:05 A.M.
