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.

Just happened minutes ago....

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???
