EARTHQUAKE AGAIN! Another Whopper!

[Ocklawaha]

I can't believe it has happened again and this time closer to home! Got to check with my sister and make sure nothing in my desert cabin collapsed.

6.9 Earthquake
Minutes ago 7:42 EST, 4:42 Pacific Time, 9:42:32 Zulu

Centered outside of Guadalupe, Baja California

Rolling - Rocking motion quake

Magnitude - 6.9

Depth - About 20 Miles

Information, Massive quake, no immediate reports of damage but this one is big enough to make it's own news.
Phoenix AZ, and Manhattan Beach CA, both felt a strong Temblor.

DISNEYLAND under emergency evacuation...

Not believed to be an immediate threat of Tsunami.


Here we go again folks! Still waiting for the Charleston or St. Augustine, faults to wake Florida the hell up!

Just heard they upgraded it to 7.2 - time to invest in ocean front property in Nevada?

SD=San Diego!  I was thinking that was one hell of quake in Baja to be felt in South Dakota!!

The look on her face is priceless.  I am quite sure that was the look on my face the first time I felt a quake... very unnerving...

was actually talking with my friends in San D when this happend. They had alot of aftershocks with this one apparntly

Cheney better watch out hes getting a little careless with the HAARP

[LPBrennan]

When was our last earthquake here? 1893? I don't have my Davis book handy. Th people felt shocks from a quake in Charleston, which sits on a nasty fault.

[Lunican]

I believe there was a small earthquake near southpoint just a few years ago.

NY Times has an article about an earthquake in 1900.

In college at South Florida it was required to take one course in science, so I chose Introduction to Geology, as I felt it would be useful in my hobby of model railroading- building realistic scenery. Making rocks that look like rocks.

The professor lamented that, geologically speaking, Florida was one of the dullest spots on Earth. Ever since the break-up of Pangea, Florida has been on the trailing edge of its plate, apparently. There is no tectonic activity of any significance (mountain building), no vulcanism, not much of anything. The peninsula is a low anticline- a gently upward arching fold in the Earth's surface. Sometimes it has been above sea-level, sometimes below. Florida is bedded on various types of limestone going down thousands of feet, with sand on top. The sand caused by ocean activity on the shore, mostly. The limestone gives us our Karstian topography: many springs, caves, disappearing rivers, sinkholes and swarms of lakes. That's interesting enough, actually, and deadly- diving in our many underwater caves is not something the casual diver does, and experienced divers die often enough.

The limestone has faults in it, but these are mostly localized cracks and deformities, with no connection to the troublesome faults which have been so active around the world lately.

About thirty years ago I flew to Savannah with a friend in his Aero Commander shortly before Christmas. From 5,000 feet, it was easy to see the ancient sand dunes that had been created as the sea level slowly changed over the ages. (I could also see the long trails of mud stirred up by shrimp boats off shore.) The right-angle bends of the St. Johns in this area are the results of the prehistoric lagoons behind the beach dunes.

No mountains or volcanoes? Well, they can be beautiful, but they also produce avalanches and eruptions. I'll stick with the sinkholes.

A whole page without referencing HAARP?

Someone is slacking.

[Sportmotor]

no mentions of serbs either

[LPBrennan]

No mention of Serbs? Well, the Karst region, which gives its name to the type of topography we have under Florida- easily eroded limestone- is in the northern and western part of what we once called Yugoslavia (Jugoslavia on older maps) and therefore mostly in Slovenia and Croatia, along the Dalmatian coast. (Spotted dogs? Yes- I spotted a bunch of them!) Serbia is inland and to the east. Not to say that Serbs never fell into a sinkhole in the Karst. Or that they wouldn't be happy to kick the Croats and Slovenes out and take it over (or that they'd return the favor if they could)!
