It seems to me California is registering the most activity with the majority of the action being in the 1.0-3.0 category with a few that are bigger, on some days they register hundreds of quakes under 2.0 , there must be a multitude of seismic sensors throughout the state.chaser, I just went to the global incident web site. Within the past 2 hours there were 30 quakes reported in Cal, Alaska and Nevada. That is one quake every 4 minutes. None of these were big boys but is it my imagination or are things heating up?
I googled your question Al, and it turns out you were pretty close. The so-called "experts" seem to think 2.5 is pretty much the lowest quake a person would feel. But, there are zillions of variables ranging from the distance to the quake, to how sensitive the person is who felt it, to feeling stuff like that. And how many others felt it, to what were they all doing at the time they felt it.How big do the quakes have to be in order to feel them, just guessing but maybe 3.0 ??
