[FashionD]

I felt it. About 12:30p or so?
I also felt one on Sunday morning around 10:30.

I thought San Diego was pretty safe from earthquakes. What are the chances of a large earthquake causing a lot of damage in San Diego?

As I've said before there are only two kinds of earthquakes in San Diego, the ones you sleep through, like todays, and the kind that wake you up, but aren't worth getting out of bed for.

The chances of a big earthquake in San Diego seem very small. I don't recall an earthquake in San Diego in recorded history being greater than 4.5, and a 4.5 quake wouldn't even get me out of bed.

Not sure how long you've been in San Diego, but the strongest one I felt was back in 1986 and measured a 5.3 on the richter scale. Trust me, it was more than enough to get you out of bed!!

Here's an archive description of it from the USGS (My roommate is an earthquake researcher and provided this info):

JUL 13 CALIFORNIA-MEXICO BORDER REGION. ML 5.3 .
Twenty nine people injured, one critically and at least
50 buildings damaged in the Newport Beach-San Diego
area. Preliminary estimate of damage 720 thousand
dollars. Also some damage reported in the Tijuana area,
Mexico. A small landslide occurred near Lakeside in
eastern San Diego County. Felt throughout the coastal
area of southern California, from Santa Barbara to San
Diego, east to Palm Springs and as far as Yuma,
Arizona.

Regarding the history of earthquakes in San Diego, the last paragraph suggests that we are at risk for a big earthquake to occur at some time:



Faults and Earthquakes in San Diego County

Thomas A. Deméré, Ph.D.; Curator of Paleontology

Like the rest of southern California, San Diego County has a number of active earthquake faults. These faults generally run in a northwest-southeast direction and are the product of crustal stresses associated with movement of the Pacific and North American lithospheric plates.

From east to west the major active faults consist of the San Jacinto, Elsinore, La Nacion, and Rose Canyon faults onshore and the Coronado Bank, San Diego Trough, and San Clemente faults offshore. Often the traces of these faults are marked by river valleys and canyons such as in the Lake Henshaw area where the Elsinore Fault passes along the northeast shore of the lake, or in Balboa Park where the small Florida Canyon Fault passes along the western slope of the canyon and beneath the parking lot of the Naval Hospital.

Since 1984 earthquake activity in San Diego County has doubled over that of the preceding 50 years. In modern times the strongest recorded quake (seismographs were not developed until 1934) in coastal San Diego County was the M5.3 temblor that occurred on 13 July 1986 on the Coronado Bank Fault, 25 miles offshore of Solana Beach.

Historic documents record that a very strong earthquake struck San Diego on 27 May 1862, damaging buildings in Old Town and opening up cracks in the earth near the San Diego River mouth. This destructive temblor was centered on either the Rose Canyon or Coronado Bank faults and descriptions of damage suggest that it had a magnitude of about 6.0.

In recent years there have been several earthquakes recorded within the Rose Canyon Fault Zone as it passes beneath the city. Three temblors shook the city on 17 June 1985 (M3.9, 4.0, 3.9) and a stronger quake occurred on 28 October 1986 (M4.7).

Ongoing field and laboratory studies suggest the following maximum likely magnitudes for local faults: San Jacinto (M6.4 to 7.3), Elsinore (M6.5 to 7.3), Rose Canyon (M6.2 to 7.0), La Nacion (M6.2 to 6.6), Coronado Bank (M6.0 to 7.7), San Diego Trough (M6.1 to 7.7), San Clemente (M6.6 to 7.7).

I must've slept through this one. And I didn't feel Sunday's at all. I was at work (in Solana Beach) and felt nothing.

Wow I was just in Sandiego from NYC and felt a quake that occured in LA. I was on the phone with friend there as it happened, I felt it about 7 seconds later. Never experienced anything like that in my life. Could feel it in every cell of my body, it must have some relationship with the atmosphere in some way. Califronia is simply Beauftil, I want to Move there from NYC, My only fear there would be a sea quake than a huge wave. The best home to live in in an earth quake zone is a trailer with the wheels kept on and no major foundation.....
