The quake was magnitude 4.7, 13 miles outside of Lancaster.
(To be honest, I only checked because I wasn’t sure whether it was an earthquake or just someone moving heavy equipment around in the building.)
Update 4:05pm: Apparently it wasn’t anywhere near Lancaster, but off the coast of Baja (and 5.1).
The report’s still there, but the shake map has been removed, and the Lancaster non-quake is no longer on the map
I felt it down here in Carlsbad. We all knew immediately what it was. The stacks of boxes in the warehouse were swaying. V. odd. Definitely not heavy machinery.
(Yes, I filled in a questionnaire, since I figured our collective recognition of the event was interesting enough — hell, people down in San Diego also felt it — La Jolla/Mira Mesa area, mostly.)
My coworker, in the next cubicle over, didn’t even notice it!
Interestingly, it seems the first estimate was waaay off. It was actually a 5.1, off the coast of Baja.
The old shake map’s gone, and the mark isn’t on the recent quake maps anymore. Here’s the updated shake map.
Actually, the news media have it as both — 3:28pm off the coast of Mexico, 3:29pm near Edwards AFB.
Some of my coworkers felt both.
I did feel two sets of shaking, but they were so close together (maybe five seconds apart) that I assumed they were the same earthquake.
I’m inclined to go with the USGS on this, though.
OTOH, I wish they’d stop moving their web pages around! The original shake map URL now contains a map for the off-the-coast location, and the URL linked to from the quake info page is now 404-compliant…. Don’t they know that cool URIs don’t change?
Now half the links are already dead within an hour of posting.
Grr…
