CONCORD (CBS/AP) — A string of moderate earthquakes has rattled the East Bay Sunday, shaking buildings. There were no immediate reports of injuries or damage.

The U.S. Geological Survey says an earthquake with a preliminary magnitude of 4.0 hit at 2:13 p.m. Sunday. It was centered a mile south of Concord.

Three smaller quakes shook the area in the moments before and after the larger one. A magnitude 2.5 earthquake hit at 2:01 p.m., followed by the 4.0 at 2:13, and a 2.7 magnitude quake at 2:14 p.m. A magnitude 2.4 shook the area again at 2:28 p.m. A magnitude 1.6 hit at 2:56 p.m.

the 4 was probably just ....below the threshold for tremors Id have felt in the “north bay” in Marin County

[TribalPrincess2U]

Quick all thugs envited to East Bay Cities for big conference on how to screw white people and......

[JimSEA]

SIL called and told us she felt it in West Bay/Daly City.

Oddly enough, and I can’t believe I’m saying this as it would have been a normal statement 5 years ago.

We’ve been earthquake-free in KS-OK for two whole days.

Instead they’re in Michigan and California now.

Bush's Fault again.

Boy he's been active recently.

[onedoug]

Typical northern CA seismology.

Unless I'm mistaken this is the 3rd earthquake reported in the U.S. in the last couple of days. California, Michigan and now Connecticut.

[concerned about politics]

There was an earthquake this weekend near Galesburg, MI. A 4.2
Another weekend quake, much smaller at 3.0 occurred neat Canton, MS.

[RaceBannon]

I thought I felt something at the range on highway 4 during a match I was in. Probably what broke my string of perfect Varmint class scores (39/40), grrrr... Bad Earth! No shaking while I’m on the bench!

I'm mistaken this is the 3rd earthquake reported in the U.S. in the last couple of days.

There are several earthquakes every day in the US, often many earthquakes a day.

[VeniVidiVici]

Due to all of the fracking in the Bay area I’m sure.

[knarf]

No ... I think the earthquake machine is Roves .... Dubya’s innocent on THIS one.

[bert]

the big’un....... it’s coming

[conservativejoy]

Sorry. I saw Concord and east bay cities and thought they meant Concord, CT. My Bad.

[Yo-Yo]

All these earthquakes are because of Fracking.

(Please read tagline...)

[anoldafvet]

Damn climate change.

[Polynikes]

Whats worrisome is not that it is swarm in the concord area but is extraordinarily shallow, approx 1km depth.

[Nifster]

Oh for goodness sake.....Those don’t even qualify in the Bay Area as news worthy....Must have been a slow news day
