A statistic I’ve seen—but am unable to verify at the moment—is that about 20% of the human-perceptible earthquakes that occur on Earth each year take place in Japan. I’ve been living in the Tokyo area for many years. Yes, it’s not unusual to have three or four earthquakes a day nationwide, but most are small and felt in only a limited area. I typically notice one every month or two on average. More occur, but it’s easy to miss the smaller ones if you are outside, on a train, etc. An exception was after the huge Tohoku quake on March 11, 2011. For months thereafter, I felt aftershocks every day. Here’s the nationwide list for a couple of weeks later: https://typhoon.yahoo.co.jp/weather/jp/earthquake/list/?sort=1&key=1&b=34000 https://typhoon.yahoo.co.jp/weather/jp/earthquake/list/?sort... There were over a hundred quakes just on March 27, all strong enough to be felt. We may have seemed to get a bit blasé about earthquakes then, but I don’t think people here ever really get used to them. When the shaking begins, you never know whether it will end quickly or, in a few seconds, get much stronger and possibly destructive.
