Hmmm....

[Dr. Eckleburg]

Bring back the landslides.

I just saw this on the map!

WOW .. another one?

WOW .. another one?

[Echo Talon]

glad I live in the central time zone. :D tornado take me away... :D

[Black Tooth]

Isn't that too far west in the ocean to be associated with the one the other night?

[kingu]

Landslides are more entertaining, so long as you aren't around them. Blegh. Probably a 6.5 on the magnitude scale and I'm sure that Lucy Jones will happily tell us that this is hardly unusual to have an aftershock of this magnitude and no, the world is not ending.

[BigSkyFreeper]

COOL!!! Another one!!

[onyx]

Ermie! I have a cake for you on another thread. Borrowed it from a feller named Gary, but you'll like it.

[Davis]

Yep, I felt this one. It appears to be near the 7.2 earthquake that hit earlier this week. We Californians are used to earthquakes, but two shakers this close together in just a couple of days even gives me the heevie jeevies...

[Central Scrutiniser]

My prediction from earlier today came true!!!!!


To: doug from upland
I predict a big earthquake (within) in a month with a vowel in it in the next 5 years, and that there is a 50/50 chance it will be on an odd numbered day, and a 50/50 chance that it will be during the day time, and a 50/50 chance that it will be in the first half of the month. There is a 50/50 chance it will be at sea, and a 50/50 chance it will be in this hemisphere.

Now, please give me $50.

(note, the odds on EVERYTHING are 50/50, either they will happen, or they will not)

Thanks Keith for posting the map.

This is becoming interesting. What have we had now 5 good ones in the past week?

It's only a matter of time before that 9.6 rocker hits.

[onyx]

My room is moving... color me happy... it's not the earthquake, but it'll do. :)

[bd476]

Awesome map, Ernest!

[ARCADIA]

Earthquakes, hurricanes, earthquakes, hurricanes...what ever happen to a good old fashion rainy day?

[Brad's Gramma]

Oh heck. Put me on the list if I'm not already.

Seems like it's going to be used a lot in the future....

Seems to be another one in Petrolia.

I want a 10! Like ME!

[bd476]

Landslides for whom? Free Republic.com is based in California.

[BigSkyFreeper]

The room is moving here

The (B) will do that.

[Ernest_at_the_Beach]

That's from the Alaska Center.....whatever it's called.

[Black Tooth]

Just happened minutes ago....

[kingu]

That 3.1 is a 3.9, and is east of the 6.9 that happened twenty minutes ago. Hmm.

[Crazieman]

Did you feel it? (Fill it out) :)

[onyx]

What the b fails to accomplish the p's will. My room is moving... nicely.'

[Brad's Gramma]

YOU may leave the thread.

Now. Shoo. Scram.

[Davis]

It felt stronger than the 7.2, but appears to be a few miles farther out. Must not have been as deep as the last. They are both in the same general area where we get most of our shakers up here. On the triple-plate junction.

[bd476]

Yes, and this one is a surprise. Earlier today the two local leading scientists from USGS were saying that while the earthquakes might be somehow related (the Chilean, the Aleutian Islands, the Anza quake and now the Yucaipa quake) they were going to have to study them further to determine if there in fact was a connection.

Guess they'll be up all night long now.

[Brad's Gramma]

WHERE is Petrolia???

[onyx]

We're gearing up for the biggie. I do ot want to miss it, so I will predict it happens beofre July 13th. How's that?

[Prophet in the wilderness]

Wasn't there a earthquake earlier today in Southern California ?

[inkling]

This just in: Amnesty International is demanding Bush stop continental drift.

[Blue Champagne]

Good evening, fellow quakers...

http://www.data.scec.org/recenteqs.html

[inkling]

Yep, 3.9 near Yucaipa, CA, if memory serves.

[onyx]

Yes.

[Brad's Gramma]

I want a 10! Like ME!

We'll deliver one to your new home and tell all the neighbors it's YOUR housewarming gift to them! :)

[Black Tooth]

Just had one on land, 3.9 south of Eureka about 40 miles

[Black Tooth]

I think that was a 4.9 in SC today.

[inkling]

Correction, that was 4.9 in Yucaipa. (reminder to self, proof, then post :-)
