Three hours ago, at 18:24, an earthquake measured six (on seven) on a Japanese scale, (and seven on the Richter scale) did hit Miyagi prefecture (near Sendai city). There were no victims apparently.

Tokyo, nearly 400 kilometers south, was hit too (I was in the office, on 15th floor, when it happened). It was not very strong, but quite long :-(

The full earthquake data is here, but I don't know how long this link will be valid...
