Shake, Rattle, and Roll

From the Preliminary Earthquake Report:

“A minor earthquake occurred at 9:55:16 AM (PDT) on Saturday, October 30, 2004. The magnitude 3.4 event occurred 15 km (9 miles) WSW of Boulder Creek, CA. The hypocentral depth is 8 km (5 miles).”

There was a thump sound (no movement, at least that I felt), and then just a second or two of rattle. I (and Bob, too) figured it was further excitement from Parkfield, or maybe Paso Robles. We were amazed to discover it was only 9 miles away; both of us would have figured something so close would have been far more exciting...

We’re still waiting for the CISN shake map…
