Waves have been reported between 4 and 7 meters. The earthquake was initially reported as a 7.2, then a 7.9, then an 8.1, now an 8.9.
NHK has been the best source of video that I've found and the anchor there is much less annoying than CNN's.
On Twitter, @W7VOA has been the best source of information, but it sounds like the worst is over at this point.
