Makes me think of the fact that the UK officially has over 300 earthquakes per year, but any you would actually feel are unheard of.

There're like 20 magnitude 4 earthquakes worldwide every day too. Even those are rarely noteworthy.

Huh. I never looked this stat up, but I assumed it was close to zero. The one time I had the house rattled in England with a 4.0 was a big surprise.
