def is alright, his family is alright....
For good info about the tsunami, check the wiki page http://en.wikipedia.org/wiki/2011_Sendai_earthquake_and_tsunami
It's not the worst tsunami ever, but it is about the worst earthquake the country has ever had. I have a few friends around the region worst hit, Sendai and Iwate, and they were shaken but safe.
It's going to take a few days to figure out all that's gone wrong. We can be thankful that we live in the modern era, and building regulations in Japan are stringent at this point, and the country is about as earthquake-proof as you can while still having high-rise buildings. Compared to the Kanto quake near 100 years ago which took over 100,000 lives in the disaster after. (http://en.wikipedia.org/wiki/Great_Kanto_Earthquake) So, it's a tragedy, but nothing as horrible as what happened in Haiti before, where the earthquake was smaller, but the damage far far greater.
My heart goes out to those in trouble though. My friend was away from his wife, and had no phone connections for hours, it would be hard not to panic. The staff at my work place spent much of the afternoon trying to get in touch with people. Crazy day.
