Japan's worst earthquake in more than a century

When many of my friends started writing about tsunami in Japan, I didn't take notice. And then there was a Facebook status from my former professor about the earthquake. He was in his office (I've been in that office many times) and books fell off his two ceiling-high bookstands, he had to stop two wobbling computer monitors from falling.

Now, I have experienced many earthquakes while in Japan and by the end of my stay there had even learned not to be scared. My wife would often wake me in the middle of the night, scared, but I would just say "It will soon end, go back to sleep." And it would end soon. If I remember correctly, the worst earthquake I had while in Japan was 6.5 degrees on the Richter scale.

But this one seems to be a really bad one. I have many friends who live and study in Japan and I'm somewhat worried. From Facebook messages it looks like there are no casualties or injured in Tsukuba, at least among the people I know. I hope there will not be.
