According to the United States Geological Survey, there has been an average of 3051 earthquakes per annum in the United States since 2000.
Also according to the USGS, there have been 901 earthquakes in the United States in the past week. All of these have been relatively small — mostly 1.0 to 2.0s — but the sheer volume is disconcerting. The cluster around Yellowstone is particularly, uh, interesting.
I’m no scientist, but my understanding here is that this is either A) Good because it means that lots of pressure is being released harmlessly, or B) Bad because there’s more pressure than can be let off easily through these earthquakes.
Anyway, I’m going to fill my car’s gas tank, just in case.
