Where On (Google) Earth? #48

Welcome to all of the competitors! I've explained things to my students, and I imagine everyone knows the drill by now. The Schott Rule is in effect.

Post time is 1745 on the leftist coast.

Cheers everyone...

M = 4.7, WNW of Lake Elsinore

My brother, his buddy Eric and I were reading the NYT yesterday morning and drinking our Sunday coffee yesterday morning (RIP Alfred Peet) when there was a small creaking sound. It passed right by me but the cat popped her head up and Eric asked "What was that?"

After a few seconds, the familiar rocking began, lasting ~10 seconds. "Earthquake" I replied. We discussed how big and how far away while I waited for my laptop to wake up and find the network. I guessed 3.5 and Yorba Linda, because most of the half-dozen small earthquakes we've seen the past 10 years seem to have originated in that general area.We marveled at how well the USGS Earthquakes page works these days, as the event description was posted within 2 minutes, and it showed up on the map within 4 minutes along with Lat/Long, and the moment-tensor solution. I know that within the last year it's taken as long as 10 minutes to see data posted ("10 minutes! But I want it now!"). Click on the image below to access the USGS information page on this earthquake:The image below is a map of the major faults in Southern California available on the page of the Southern California Earthquake Center. Click on it, then on the purple shaded region, then on the purple blue fault line in the lower right of the image to get a description of the fault that produced this earthquake.
