Earthquake Hits Mid-West!

[cityboy-stl]

I was at work and didn't feel the aftershocks. But aftershocks are good. That means the one last night was not a fore-shock. Hopefully this one doesn't shake loose New Madrid. It wasn't that far away. Although I did find this article that says the chance a New Madrid quake is not great. http://www.sciencedaily.com/releases/2008/04/080416174630.htm

what are you all complaining about???? some of us have worse things to worry about.

Huge California Earthquake Predicted Within 30 Years

HUGE STATE QUAKE PREDICTED WITHIN 30 YEARS
By David Perlman

San Francisco Chronicle

Tuesday, April 15, 2008

SAN FRANCISCO - A strong and deadly earthquake is virtually certain to strike on one of California's major seismic faults within the next 30 years, scientists said Monday in the first official forecast of statewide earthquake probabilities.

They calculated the probability at more than 99 percent that one or more of the major faults in the state will rupture and trigger a quake with a magnitude of at least 6.7.

An even more damaging quake with a magnitude of 7.5 or larger, the earthquake scientists said, is at least 46 percent likely to hit on one of California's active fault systems within the next three decades. It probably would strike in the southern part of the state, the scientists warned.

The report by the team of federal and state geologists, seismologists and geophysicists does not significantly change the probability estimates for future large quakes on the Bay Area's major faults that were calculated five years ago, but it does provide the first detailed forecasts for quakes in the Los Angeles area, specifically on the southern San Andreas Fault, the San Jacinto Fault and the Elsinore Fault.

Quakes like those would be similar in magnitude to such deadly temblors as the Loma Prieta, which claimed 63 lives and caused at least $10 billion in damage in 1989, and the Northridge quake in the San Fernando Valley in 1994, which killed 57 people and caused more than $12.5 billion in damage.

^ Yeah, someone from California at work today was laughing at all of us being so upset by our "puny earthquake".

Geologists also say that the Pacific Northwest is due a quake above 8 in the next 80 years -- in fact that we're overdue.

I don;t mind being overdue on a book, but I hate being overdue on a quake.

I didn't feel the aftershocks, but the news here has just gone bat-shit crazy with crazy nonstop earthquake coverage.

Everything is relative. People in California may think our 5.4 was puny by there standards. On the other hand, we might find their tornadoes to be puny.

 

[Absolut]

^^ Yeah, the news here is going crazy too.

Lots of "EARTHQUAKE 2008!" moving graphics and "THE '08 QUAKE!"



Por ejemplo -

(just one of the examples of a local news station's website...)

We see this building in Louisville that had bricks fall down over and over and over.

Californias think they're all special. They may have more frequent quakes, but the New Madrid quake in the 1800s puts to shame anything California has had to offer. When the fault ruptures again, it's going to be catastrophic.

Let's not forget the Pacific Northwest. They're long overdue, as well. When their fault ruptures, it could easily produce one of the strongest earthquakes ever recorded...not to mention a massive tsunami that could kill millions.

I slept right through it.

My partner and I live in southwest lower Michigan and we felt it. I was getting ready to take my shower and he was feeding the dogs. The dogs freaked out! Our puppy ran to the corner and started to wine like crazy. I heard a rumble then felt a little shaking. That was CRAZY! We are not use to things like that in Michigan!

I've been through a few, but we had a really bad on (with accompanied tsunami) in 1908.

So when we had tremors in PR, we were grateful, since it means no big one!

it was like four seconds in Indy, and I was in sweet dream, and thought it was just a dream.

Why is it that all earthquakes (at least the ones I'm pretty familiar with) happen in the morning time? I find that a bit odd.

The only other one I felt (back in 1986) was about 6 or 7 in the evening. Didn't the big northern California one in 1989 happen just as a World Series game was getting ready to start?

any of you who felt it, was there anything to tell you how much movement you actually had? Dishes or such sitting on smooth shelves are good candidates.

I have a twin-stack of CD's on my office desk that's about two feet high. The double-stack was swaying close to an inch at the top, but didn't topple. I felt the quake with no problem, and I knew immediately what it was. Yes, I was still up and still in my office at 4:30 in the morning, though I was off to bed within 20 minutes or so.

Indeed it is. The Mississippi River Valley is no drainage accident, but the early development of an active New Madrid fault line,

Actually, the river itself probably formed because of drainage, as it's a long river extending very far north and south of that fault system. However, the massive New Madrid earthquake in the eighteen-tens did change the course of that river over a number of miles, and I think in some places it actually flowed backwards.

Indeed the New Madrid earthquake was larger than anything that's ever been documented in California. (No doubt, before such things were recorded, there were quakes there and elsewhere much larger than the ones we're most familiar with.) I guess that the 1964 Alaska quake has been the most massive North American quake in my lifetime, though ones in Mexico City (1985) and Managua were certainly no walk in the park.

nstead, this was the Wabash Valley system that straddles the Illinois/Indiana border--about 150 miles northeast of the New Madrid fault and about 130 miles east of St. Louis. We had two pretty moderate aftershocks today too.

Thanks for the clarification on this, I always assumed the entire fault system down that way was called the New Madrid System. I only felt the main quake, though the aftershock mentioned above that was felt in Springfield came while I was asleep and I didn't notice it.

We see this building in Louisville that had bricks fall down over and over and over.

Didn't the bricks fall down only once? LOL.

There was another aftershock this morning. My nerves are shocked too. I'm in a panic every time a truck goes by the house and it vibrates a little. There's a lot of speculation that this might "shake loose" New Madrid and cause a really big one.
