Obviously the tremendously powerful earthquake and surreal tsunami is dominating this morning's conversation - always puts things in perspective.  This appears to be the 5th most powerful earthquake since 1900 - but closest to a large city.

1. 1960 -- 9.5 -- Chile

2. 1964 -- 9.2 -- Prince William Sound, Alaska

3. 2004 -- 9.1 -- Sumatra

4. 1952 -- 9.0 -- Kamchatka, Russia

5. 2011 -- 8.9 -- Friday in Japan

6. 2010 -- 8.8 -- Offshore Maule, Chile

Obviously when a tsunami is involved the video is nearly unbelievable - almost out of a movie.  NYTimes blog has a series of videos from various locales in Japan here
