The magnitude 8.9 offshore quake unleashed a 23-foot (7-meter) tsunami and was followed by more than 50 aftershocks for hours, many of them of more than magnitude 6.0.
Quake off the east coast of Japan; lots of damage there from the quake and tsunami, this report says more than 200 dead. And tsunami warnings all over the Pacific. A bunch of videos here, though when the site opens you have to listen to a Jag commercial before the first plays. And the commentator can't help making a idiot statement about 'places threatened by global warming' while talking about the whirlpool.
One thing strikes me: Japan, quake this size and all the aftermath, several hundred dead; quake this size hits a second- or(especially) third-world area you'd have thousands already. Advancing to better ways makes a big difference.
