San Ramon Quakes Shake Claycord

Who felt a little jolt in Claycord within the last few minutes?

The cause is two 3.5 quakes in San Ramon.

Didn’t feel a thing!

Felt it in Clayton, one quick jolt…no real shaking. Thought it might have been an accident/explosion at a refinery or something.

ClayMom October 19, 2015 at 4:37 PM

I did! My toddler didn’t feel it or care though… USGS is reporting two quakes 6 seconds apart, both 3.5 magnitude?

TT October 19, 2015 at 4:39 PM

I did in Concord.

I was home watching the news and I felt the small jolt at approx. 4:20 PM today.

According to the leading scientific climatologists the weather this time of year is prime for earthquakes.

If you can’t believe the NOAA who else is there?

Felt it in Clayton.

Was in garage. The entire garage shook. Going to make that emergency kit. My dog and cats freaked out. Live across from Clayton valley charter high school.

Didn’t feel it in Northern Pleasant Hill. Additionally, there is no such thing as “earthquake weather”. Sorry but you’ll have to identify the so-called “leading scientific climatologists”…..nonsense!

Felt nothing at 94598.

Cellophane October 19, 2015 at 5:03 PM

Quake magnitude updated, 2.8.

Amber October 19, 2015 at 5:14 PM

The recent swarm of earthquakes are caused by fracking by the evil oil companies.

Clayton Mom October 19, 2015 at 5:15 PM

Felt it in Pacheco!

I heard a slight rattle, but felt nothing.

My cats are not quake reactors, unlike past cats that bolted into the deepest, darkest parts of the house. These two are useless.

Didn’t feel anything in the Hidden Lakes area of Martinez.

There is no such thing as “earthquake weather”. Statistically, there is approximately an equal distribution of earthquakes in cold weather, hot weather, rainy weather, etc. Very large low-pressure changes associated with major storm systems (typhoons, hurricanes, etc) are known to trigger episodes of fault slip (slow earthquakes) in the Earth’s crust and may also play a role in triggering some damaging earthquakes. However, the numbers are small and are not statistically significant.

Heard the building creak in walnut creek

Maryanne October 19, 2015 at 5:59 PM

Didn’t feel a thing, watching the alcs baseball game

Mailma October 19, 2015 at 6:19 PM

Didn’t feel it in N Concord. My cat has been acting scared the last couple of days

Cowellian October 19, 2015 at 6:24 PM

Nope!
Not a thing!

anon October 19, 2015 at 6:35 PM

I didn’t feel anything but my dog is hiding in the bathroom

ML October 19, 2015 at 6:42 PM

Didn’t feel a thing. I work in San Ramon every day in a new post tensioned cable parking garage (these structures are typically a bit bouncy) and have only noticed one quake while there. I thought it was a forklift rolling by.

Mr Rogers October 19, 2015 at 6:57 PM

Didn’t feel it but my dog and the dogs in the neighborhood were barking for some unknown reason.

slagheap October 19, 2015 at 7:18 PM

@GRX #10 – nope, no such animal as earthquake weather.

Led October 19, 2015 at 7:28 PM

I felt it in Moraga at my desk. Very brief little wiggle, 4:22pm, give or take a minute or two.

Wage Slave October 19, 2015 at 7:30 PM

According to the USGS site, there have been 213 earthquakes now in that San Ramon Swarm over the last seven days, most of which have been too small to feel. They are all considered to be on the Calaveras fault.The Calaveras has not had a known major damaging earthquake on the northern section in historical times.

There have been swarms like this in the San Ramon/Danville/Alamo area in the past. There was one back in the early 2000s, I recall one in ’91 or so centered in Alamo, and there have been two or three in the decades prior, all centered in a specific area. Geologists don’t seem to know exactly what causes them, but that they are not an indicator of a larger earthquake being imminent.

Fascinating to wonder what might be happening right under our feet.Strange planet we live on.

Small jolt at 4:21, but was not sure at the time. Clayton on Keller Ridge.

GRX October 19, 2015 at 7:56 PM

Yup, it’s earthquake weather. Feels about right.

Mimi (original) October 19, 2015 at 9:35 PM

Felt nothing. That’s what work will do to you.

Duchess of Martinez October 19, 2015 at 11:10 PM

Looks like there were a total of four when I check the earthquake site. Didn’t feel anything but dogs all over the neighborhood kept barking like there was an earthquake, more than one occasion. Our security system went off in the garage at the same time but could not find the cause. Wondering if the alarm was tripped from that?

Duchess of Martinez October 19, 2015 at 11:18 PM

…oops
Forgot to add,
Mt. View sector of MTZ
