I do now because we just had back to back 4.0+ in CA. I don't think these are aftershocks I think this is all just buildup still.

The official USGS word on that is that there is a 5 to 10 percent chance of an equal or larger quake within the next 7 to 10 days. You can read the whole aftershock report on the 6.5 quake here.

quake.wr.usgs.gov...

My spidey sense says there's still something up. But I feel it is bad juju to speculate too directly.

Hmm, any idea what mag you think it might be? I sure hope alot of people along the coasts are prepared just in case!

Well, a 6.5 in itself is quite large enough to cause very serious damage had it happened in the right place at the right depth. As it was it was centered off shore and the closest cities were small.

So there's really nothing to say except always be as prepared as you can. Anything larger than a 6 means I hope you have your earthquake kit ready. (I don't. D'oh)

Exactly what quakewatcher said. Nobody really knows, just best to be prepared. Don't go all crazy and buy stuff but take a look at the survival forum if you don't currently have a setup at home. It's always good to be prepared.

We are very lucky this 6.5 wasnt closer to the surface and in LA.

I had a guilty feeling when I scrolled past this thread under the Recent Posts this morning!

Wish I'd listened to my gut instead of going off towards something more sensational!

Thank you,Quakewatcher,for keeping this up to date.

I live "on the edge",in more ways than one. I am in the area around Eureka where this took place,and I can tell you,it really shook things up!

We were just thankful for no tsunami to come along afterwards,or I might not be writing this right now!

Anyhow,please keep us all informed as you can!

Much appreciation,..."Not Over the Edge-Yet!"

Two Indonesian quakes punctuated the continuing aftershocks offshore California and then, just now, a 4.1 offshore N. Cali

I'm beginning to think there are rather more than usual aftershocks to what wasn't a huge quake to begin with. After the 5.8 on 31 Dec 2009 on the Mexico/Cali border there were a dozen or so aftershocks...

And here are the aftershocks so far for Jan. 10:

2.6 2010/01/10 04:05:26 40.659N 124.653W 15.2 34 km (21 mi) WNW of Ferndale, CA

*The Geysers area has been having earthquake swarms for a few years now. There's a geothermal power plant there and some say that's when they started. (Although I haven't done the research and can't back up or disprove that claim.)

Then there is Mammoth Lake, which isn’t a mere volcano but is a much more dangerous caldera and one that has blanketed the Southwest more than once under a lot of debris. ΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩΩ It is rather amusing to me that this dragon that is one of the bigger dragons on earth—though smaller than the immense Yellowstone dragon lord—is presently spewing out lots of CO2: Carbon Dioxide and Helium Discharge from Mammoth Mountain

SOURCE: emsnews.wordpress.com...

There have been worse earthquake swarms near mammoth lakes over the years that haven't led to anything major (besides really angry property owners who didn't appreciate geologists warning about the volcano).

There are also younger volcanoes than the main caldera on the site, and it's more likely that one of them would go, with vastly less serious consequences.

But yeah, it's a caldera! If you want to drive yourself crazy thinking about a supervolcano though, think about Lake Toba which has no publicly available monitoring data, is bigger than Yellowstone, and is in the vicinity of multiple gigantic earthquakes. Or, don't. Kind of like worrying about meteorites striking the earth. We are just a spec of dust inside a giant's eye.

Things have quieted down significantly across the globe, since the 6.5 off the coast of CA this weekend. Yesterday was the first time in weeks that I could look at the CA map and see no red squares.

Calm before the storm? Did you hear about the sea lions that were all over the pier area in San Fransisco ? They just up and left one day last week. They went to the Northern Ca area. Looks like they would have wanted to be far away from a quake!reply to post by quakewatcher

Long Valley Report for Today:

LONG VALLEY OBSERVATORY DAILY UPDATE
Monday, January 11, 2010 9:34 AM PST (Monday, January 11, 2010 17:34 UTC)


LONG VALLEY VOLCANIC CENTER VOLCANO (CAVW #1203-14-)
37°42' N 118°52'12" W, Summit Elevation 7231 ft (2204 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

The real-time computer system located four small earthquakes in the vicinity of Long Valley caldera since the last update at 10:33 AM(PST) on January 10, 2010. A M=1.2 earthquake at 3:42 PM on the 10th was located beneath the east margin of the Volcanic Tableland (12 miles NE of Round Valley). M=2.3 and M=2.1 earthquakes at 11:05 PM and 11:49 PM on the 10th were centered beneath the eastern escarpment of Wheeler Crest (5 miles NNW and 5 miles WSW of Round Valley, respectively). A M=1.6 earthquake at 1:37 AM on the 11th was centered beneath the north toe of the Convict Lake moraine (1 mile SE of the Mammoth Lakes Airport).


------------

Four earthquakes is a blip. Let's see if this continues for another couple of days and if so start a new thread for Long Valley. (Otherwise I don't think it warrants it.)

New sequence starting in Southern California, near San Bernardino:

3.2 2010/01/11 15:33:52 33.965N 116.874W 6.6 4 km ( 3 mi) NNE of Banning, CA
1.4 2010/01/11 15:30:04 33.965N 116.869W 9.5 5 km ( 3 mi) NE of Banning, CA
1.4 2010/01/11 15:29:50 36.664N 121.295W 8.8 14 km ( 9 mi) S of Tres Pinos, CA
map 1.4 2010/01/11 15:26:05 33.961N 116.866W 8.2 4 km ( 3 mi) NE of Banning, CA
3.1 2010/01/11 15:24:00 33.965N 116.877W 10.2 4 km ( 3 mi) NNE of Banning, CA

Note the 3.1 and 3.2 are only 9 minutes apart and in the same location. They appear to be a bit too far away to be aftershocks of that 5.8 a few weeks back.

So Cal quake says Twitter, (LOUDLY!) waiting for official report will update this post.

With all of the foreshocks, unfortunately my spidey sense says this may not be the largest for this spot in the next few days.

Plus a 3.5 mag just a few miles from last nights aftershock zone, just now.
