Of course, you need to keep in mind earthquake magnitudes are measured on a log_10 scale. i.e. a 5.0 ~ 10 x 4.0. The Sendai/Tohoku earthquake was a magnitude 9.0 MMS quake. I've slept through a 4.5 when living in Tokyo. A nice map of seismic activity can be found on the website of the usgs [http://earthquake.usgs.gov/earthquakes/]
