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/]

Comment: Units and numbers to keep in mind (Score 1) 1148

Some numbers to keep in mind (where possible, numbers were verified against multiple sources: IAEA, NYT, Ibaraki prefecture radiation monitoring stations south of Fukushima):radiation dose unit conversion: 1 rem = 10000 Sv, 1. Maximum dose/year for US rad worker: 5 rem ... 2. Background radiation dose/year in US: 0.500 rem (Denver, CO: 1 rem) ... 3. Highest measured dose rate anywhere in Ibaraki: 0.00025 rem/hour (Tuesday morning) ... 4. Highest reported dose rate at site boundary: 0.1 rem/hour ... 5. Highest reported dose rate on reactor site: 40 rem/hour for several hours ... 6. Radiation dose rate at Chernobyl on reactor site in days after explosion: 10 to 5000 rem/hour (not considering dose-on-contact of ejected reactor components) ... 7. Average cumulative radiation dose for Chernobyl first responders, resulting in up to 300 acute radiation deaths: 500 000 rem ... Some newspapers keep using mSv and mrem interchangeably, never mind the factor 100 difference.

So... did you ever wonder, do garbagemen take showers before they go to work?
