".....not fore shocks......"

Lets hope so!

[I'm a former Southern Californian who endured, besides all the usual 4.5 to 5.8's over my 10 years in La-La-Land, was camping in Joshua Tree Park the morning of the 7.2 that hit near there in the desert in the wee hours of a Sunday morning over 12 years ago; my buddy and myself were in one those interesting large-boulder-strewn campgrounds that Joshua Tree has to offer and laid in our tent waiting for that one to finish.......or a 20 ton boulder to let let loose and finish us {*LOL*}]

Be safe amidst the rockin'-n-rollin'.

[bd476]

Joshua Tree and that big quake - scary!

LOL, however, it reminds me of "Galaxy Quest." There's a scene where Tim Allen has landed on an alien planet in search of a rare berylium sphere.

Allen ends up being left behind by his shipmates and gets into a battle with a large Rock Monster.

While battling the Rock Monster, he's surrounded by a quasi ampitheater of sharp fanged little beasties shouting "Rock, rock, rock, rock, rock!" which coincidentally brings to mind Sunset Blvd. & La Cienega Blvd. circa 1982.

But I digress...

[jackbenimble]

Didn't feel a thing here in Oak Ridge, Tennessee.

You will when the tsunami of newly displaced illegal immigrants hits.

Thanks for posting. It does seem that the west coast is catching up on earthquakes. What's the likelyhood that is is "fore-shocks"?

The last word I heard on that was from a seismologist at Cal-Tech who said that the only certain prediction was one of random occurrence.

[Tennessee_Bob]

Didn't feel that one either. Dang - we're missing all the fun.

[LadyJMayo]

Me neither. LOL...but I guess we should be careful what we ask for! WOW, there have been an unusual number of earthquakes in TN and KY in the past month or so. I wonder if the New Madrid fault is about to blow? I just finished reading a book about that not too long ago called "The Rift". Interesting scenario.

[Paloma_55]

I should check out the research on this. When I took geology in college back in the late 80s, the quake was already overdue. The story goes that the later a quake is from its nominal cycle time, the bigger it gets.

The theory our professor discussed suggested that there is a "rough spot" in the inter-plate interface which makes its quakes bigger. LA and SF also have such spots, but this one is more dramatic. (It turns perpendicular to the motion of the quake like a tooth on a gear) and there is a theory that if it goes off big enough, it will trigger adjacent faults to break which could mean a SF and LA quake simultaneously. Not necessarily in the same hour, but within days of each other.

[LadyJMayo]

WOW...just noticed that last one was in OUR neck of the woods...east tennessee. Not Memphis. Weird

On January 21, 2003, at 8:06 pm a magnitude 7.6 earthquake occurred just off the coast of Colima.

There were at least 25 dead and 300 injured. There was extensive damage to buildings in Colima, capital of Colima, and in Manzanillo, Colima, as well as in the state of Jalisco.

There were some power outages and interruption of communications. There have been numerous secondary earthquakes up to magnitude 5.8. There was no damage at all in Barra de Navidad, Jalisco.

Several explosions occurred at Colima during June 15-21, reaching a maximum height of ~6.1 km (20,000 ft) a.s.l.

Sources: Universidad de Colima, Washington Volcanic Ash Advisory Center

You can see some short videos (~5 minutes-long) of relatively recent explosive events of Colima

The Colima Volcano, considered Mexico's most dangerous active volcano, has had several recent events, including an increase in explosive events on 7/6/99 and two eruptions in November 2000. For updates, see Volcano World. The Volcán de Colima is located in the state of Jalisco near the northern border of the state of Colima, 60 miles northeast of Manzanillo.

On Thursday, 9/30/99, at 11:31 a.m., an earthquake centered 2 miles north of Puerto Escondido, latitude 15.89°, longitude 97.07°, of magnitude 7.4 lasted for 41 seconds. There are 12 reported fatalities in Oaxaca City, Santo Domingo Teojomulco, San Jose del Progreso, Puerto Escondido, Mexico City, and Veracruz state. Many homes and buildings collapsed in Oaxaca City, 75 miles away. There was only minor damage in Huatulco; Puerto Escondido reported 15 buildings damaged, one fatality, and electricity was out. The quake was felt strongly in Mexico City, 310 miles away, and as far south as Guatamala. see reports from residents and visitors.

>Bush's fault. Halliburton. Women and minorities. yadda-yadda-yadda....

Obviously, if
gays were allowed to marry
these quakes wouldn't strike!

[falcon1966]

I live here in Puerto Vallarta which is on the Pacific Coast in Jalisco, we felt nothing........I am looking at the Pacific Ocean right now.

[BurbankKarl]

Is this quake why BofA's 800 number and website arent working?

[Mr.Atos]

The hypocentral depth was poorly constrained. What the hell does it mean?

Mile wide, inch deep... like most liberals.

[SlowBoat407]

Taglines are supposed to have meaning?

I sure hope not

[rabidralph]

The quake probably accidentally jostled a few more over the border.

[Renfield]

HOw does one change his tagline? I've forgotten, and can't figure it out.

[Renfield]

Never mind, I think I've figured it out....

[ko_kyi]

Start by constraining the hypocentral depth?
