California going off!

I was zooming in on the detail map on one in Brawley. What exactly is that when you zoom in? It almost looks like concrete surrounded by grass lands. Is it a bridge, road? I cant figure it out.

Are you in Brawley right now?

Can you give us a live update?

reply to post by Wrabbit2000

I have a sidebar EQ app.. it shows all the EQs everywhere on my desktop.. There is always some in CA.. but mostly 1.0 to 2.0 maybe

Forgive the ignorance, but how strong must it be in order to be felt? To do structural damage?

Kinda puts it into perspective:


Less than an hour later:


What I find interesting is that the Global incident map site: quakes.globalincidentmap.com... has a 17 hr duration for quakes to remain on the map. But here, the bigger ones within the last 2 hours are being removed. Not only that but there are no other quakes on the map anywhere in the World except small ones in Puerto Rico, Turkey and Alaska.



hmmmm?

Peace

Brawley is in the middle of the desert.. It is TOWN with irrigation fields all around it.. Nothing would grow if they did not pull water up from the ground. No running water really except what they get from the Colorado River.. and the rivers from Mexico that dump into the Salton Sea.. Nasty rivers.. you do not even want to eat the fish from that one. The all america canal brings us water...it is concrete..

Indeed.... I grew up in Cali and most of my family is within 100 miles of this swarm. It's normal to have quakes there every day at low levels. 365/days a year. No doubt...but I've never had page after page after page of a continuous swarm to look at before. This is odd..... I hope the trend down ATM is it settling down and ending.

I checked on the internet, that area had a 7.1 back in 1940. The swarming is what is weird. The southeastern desert area that is a "one and done" area (more or less), as you said.

earthquake.usgs.gov...

Wasn't there a swarm of Cali quakes a few weeks ago, which precipitated a large quake in Iran?

The earth is waking up, for sure. It's not a heavily-populated area, thank goodness, and this may not mean anything, but it is pretty unusual as far as frequency. The rest of the world is relatively quiet as well. Strange harbinger of......?

Just a ball park figure....

Probably like a 7ish. But even then, California has adopted strict seismic safeguards in the construction sector. Only old buildings would be damaged.

also more in Iran.

I dont see that any hit Iran. What site do you follow?

Apprears to very few anyplace else from the map I'm looking at. A small one in Turkey but that about it.

From what i know its the magnitude plus the depth that matters.
If it is shallow and high in magnitude then hold on if its deep and high magnitude then not so bad.

Earthquake "Booms" being heard?

EL DORADO COUNTY (CBS13) – People from all over El Dorado County say they’re hearing loud booms several times a week, but there are many theories on what is causing them.

How big does it need to be for a person to feel it? What an earthquake feels like depends on many factors: the magnitude, your distance from the hypocenter (considering the depth of the quake), the type of soil or rock you are on, the building you are in or if you are outdoors & what you are doing at the time. Under ideal conditions, you are lying or sitting still in an upper floor, right on top of a shallow earthquake, you might feel a 1.8 if you were paying attention. Usually, however, it takes at least a magnitude of 2.0 for multiple people to notice a quake & recognize it as a quake. A 4.0 usually gets a lot of public attention if it happens under a populated area.

How big does in need to be to cause damage? The damage potential of an earthquake also depends on several factors: the magnitude, your distance from the fault rupture (not necessarily the epicenter), directivity effects, soil or rock type, type, age & quality of building construction & various geologic “special cases”. Directivity is a phenomenon related to the direction the fault rupture is propagating. If it is propagating toward you, the seismic waves are stronger & the damage potential greater than the case where it is propagating away from you, even at the same distance from the fault rupture. In general, soft sediment amplifies ground motion, so damage is likely to be worse in geographic basins, as opposed to on rocky mountains or hills at the same distance from the fault rupture. Besides magnitude, however, the most significant factor in damage is the construction of the building itself. Unreinforced masonry (URM) or adobe is by far the worst, since the materials are heavy & weak. Reinforced masonry or “retrofitted” URM buildings are somewhat better, but still may be dangerous. The best is properly built one or two story wood frame construction, anchored to the foundation & with plywood shear walls. Steel frame structures & reinforced concrete structures are usually also resistant to earthquake damage, with age & overall design being a factor.

No thank god.. I live in Missouri now.. but I will call a cousin and ask how it feels.. she lives in El Centro.. right down the road..

Hello people, I am really routing for you people in Cal tonight, because with Vulcanos and E Qs it is not a good place to be, I have been watching Earthquakes on my PC since Jan 2012 with a bit of software, here is my list of quakes today I know about.

Hoping for the best for Cali right now...

Well,

as I log-off today from ATS I would just like to leave a little comment for the record.

We had that larger 4.5 on the 8th that was more or less in Yorba Linda, which I thought was a rather weird location. I don't know if things are winding down from that one or not; alleviating pressure, in other words, as the OP has suggested.

But anyhow, if a giant earthquake does occur today it will be the height of irony as it is really beautiful here today and everyone seems to be in a great mood, including the cat. That doesn't happen very often around here.

Odd that rest of EQ hot spots are quiet. Never seen this map so bare.

I got to say, this is a little weird. Sounds like a BIG Quake is coming.... like a 10.5. but it could be anything. I hope its not too big of a quake because of the Tsumsi .But it is a little weird. can ya'll keep updating me on the earthquake?

This is right in the middle of the swarm. Pipeline construction? Fracking? Possible cause or something that could be damaged by the quakes?
