Live Seismo Dupe on July 4, 2003

This morning, July 4, at about 7:50 AM in Scottsdale, AZ. I felt a jolt and then a few seconds of a rolling motion. Very unusual for this area. A friend of mine who lives about 10 miles away confirms that she also felt the jolt and rolling motion.

The quake databases record any quakes of low Richter, and a quake with a jolt and rolling motion is not insignificant. Yet this quake does not appear on the databases. 8:00 AM Mountain Time is approximately 15:00 UTC. No such quake is recorded by NEIC or other quake databases in the international network for that time period on July 4, 2003.
