one of only two earthquakes to hit colorado effected both new mexico and colorado occured the night before the east coast earthquake just before midnight.
i didn't hear much about it other than it was 5.3 and that it hit southern colorado.

Two friends of mine in Northern California mentioned a slight tremor last night as well. One friend thought it was thunder- all that happened was some china rattled and maybe a few people looked up from what they were doing for a few seconds before going back to it.

Yeah but that quake was related to Long Valley Caldera volcano and its seismic swarm.

August 24, 2011 – MAMMOTH LAKES, Calif. – Long Valley Caldera – While the East Coast recovers from earthquake jitters, small quakes have been rocking California. A minor jolt struck the San Francisco Bay area Wednesday at 9:57 a.m., just hours after a similar temblor hit the same spot late Tuesday night. The U.S. Geological Survey says both magnitude- 3.6 quakes were centered about six miles southeast of Oakland along the Hayward fault, a major Northern California fault zone. The Sierra Nevada high country was also rattled by an earthquake early Wednesday. The USGS says a magnitude- 4.4 quake hit at 4:59 a.m. about nine miles southeast of Mammoth Lakes. A Mono County sheriff’s dispatcher says authorities have had no reports of damage. A magnitude-5.8 quake jolted much of the eastern United States on Tuesday. –Sac Bee The map on the left is the blast radius of any potential large-scale eruption at the Long Valley caldera.

We had an earthquake in Pierre, South Dakota recently. That's extremely rare since we're not even close to any fault lines.

That's the Missouri river. It's not a major fault line, at least not an active one, according to (
http://www3.northern.edu/natsource/EARTH/Earthq1.htm) this. It's apparently more likely that the compression of the earth due to glacers that once covered this area (part of a reason why the land is so rocky and covered in bluffs) is making the ground spring back. Think of how a compressed sponge will slowly rise to its original shape again.
