Davenn, I live in Oklahoma in the US, and you are probably familiar with the thousands of EQs we've been having in this state, in 2014 it was over 6000 (maybe even 7000+) of all magnitudes. It's hard to tell exactly because the Oklahoma Geological Survey stopped analyzing/reporting all magnitudes some time last year. Now, I think they're only reporting ones that are above 2.0, and still not even all of the of them until you get to about 2.5. However, even raising the specific magnitude, we still get 15-25/day reported. We used to get 15-25/day when they included even the .9s and 1.5s, etc, so things are obviously getting worse (I don't need to look at the numbers to know that though, considering I have felt hundreds over the past 2.5 years). Anyways, do you personally own a seismometer? I am considering getting one, even more so now that the OGS doesn't report them all. And unlike most people think, you CAN feel very weak ones when they're close, and so shallow; I have even felt a 1.9! Distance makes a huge difference, the 1.9 was only 1.5 miles away. A ~3.3 about three miles away feels "approximately" the same as a ~4.0 six miles away. Does the energy fall off in an inverse squared in a predictable relationship? I am guessing it's not that simple because I have read that EQs that occur on the east side of the Rocky Mountains can be felt further away than ones that happen west of them... Also unlike most people think, there ARE damages to homes from weak ones as well, primarily because of the "swarm" nature of them (e.g. I had about 1,000 of them less than 10 miles of me just in 2014, about 100 of those were 3.0+). Also because of the swarm nature of them, they damage your mind too - they are a very big nuisance, especially in the middle of the night! p.s. I don't mean any insult to your intelligence by saying "US" after Oklahoma above, but I also don't want to be arrogant and assume everyone all over the world knows each of the states in the US... but since you seem to follow EQs a lot, you probably know that state in particular!
