I used to work at USGS and they always said that seismo reports from close to the epicenter were less accurate than data taken from far away, and the USGS results are aggregated from the world seismo network, so they are the authority. The local results tend to be noisier and don't have enough distance to measure propagation of the wave accurately (I will spare you a lecture on the P Wave vs S Wave equations). I remember I used to watch the incoming data on the seismograms in my Denver office, and was always puzzled at the constant tiny quakes that would register. I finally asked someone about it, and they said "oh that's just mining operations up in the mountains." The data’s up on the site now.
