Google set up a crisis response page here:
http://www.google.com/crisisresponse/japanquake2011.html
The Google page has a person finder, maps, and information on subjects such as shelters, transportation, rolling blackouts, and donations.
To see video on events as they happen, check out NHK World (English) on the digitial over-the-air channel 30-2 from the MHz network which is broadcast from Falls Church, Virginia for the DC area. Or see NHK World streaming online at their Ustream page.
