Earthquakes

The only earthquake I had ever been in before moving to Tokyo was the M5.8 in Virginia in 2011, 460km from New York City that I didn't even feel. In Tokyo, I feel like I am being rocked asleep by them every night. Three nights ago, it was a M4.8 139km from Tokyo followed by a M4.9 32km from Tokyo. Two nights ago was a M4.8 28km from Tokyo. Last night was a M6.9 in Hokkaido, 842km from Tokyo but strong enough to make international news, lasting around a minute and easily felt in Tokyo. Don't worry though, in the M9.0 373km from Tokyo in 2011, the fifth largest earthquake since 1900 no buildings in Tokyo collapsed.
