The 1964 Alaskan quake was much, much larger and per recent scholarship, none of the New Madrid quakes were likely larger than the 1906 San Franscico Earthquake, the 1857 San Andreas quake, or the Owens Valley earthquake.
One of the reasons for the impression that trailer parks get hit with tornadoes constantly is that much of the time when they're damaged it's not from tornadoes - however, the residents of the park fervently believe it was a tornado and the media does nothing to dispute the victims.
By the time NWS survey teams come through a couple days later it's no longer in the news and people tend not to notice when it's proclaimed to be damage from straight line winds.
Yeah, 'JBC's Weather Watch was again predicting another End Of The World storm but it split in two and pretty much went around Bloomington/Normal. We barely had enough rain to get things wet. Still plenty of lightning tho.
I sent you a private email.
Lights were out from Kingshighway out Manchester all the way to Kirkwood.
Damn Rove and his weather machine.
BTW, Bush's fault

Derecho is a bow echo then =
That is incorrect.

Yeah, it gets a bit definitionally complex....

Wow is right on your link!
Late start because of the weather, but Cards are up 8-1 after 5 1/2 innings. Considering the last 2 games this is a great improvement!
http://en.wikipedia.org/wiki/New_Madrid_Earthquake
The New Madrid Earthquake, the largest earthquake ever recorded in the contiguous United States, occurred on February 7, 1812. (The largest earthquake in the continental United States was the Alaskan Good Friday Earthquake on March 27, 1964.) It derived its name from its primary location in the New Madrid Seismic Zone near New Madrid, Missouri. This earthquake was preceded by three other major quakes: two on December 16, 1811, and one on January 23, 1812. These earthquakes destroyed approximately half the town of New Madrid. There were also numerous aftershocks in the area for the rest of that winter. There are estimates that the earthquakes were felt strongly over 50,000 square miles, and moderately across nearly one million square miles. The historic San Francisco earthquake of 1906, by comparison, was felt moderately over 60,000 square miles.
Based on the effects of these earthquakes, it can be estimated that they had a magnitude of 8.0 on the not-yet-invented Richter scale. As a result of the quakes, large areas sank into the earth, new lakes were formed (notably Reelfoot Lake, Tennessee), and the Mississippi River changed its course, creating Kentucky Bend. Sandblows were common throughout the area, and their effects can still be seen from the air in cultivated fields. Church bells rang in Boston, Massachusetts. Since the area was less developed at the time, damage was minor compared to what would happen today.
A request dated January 13, 1814 by William Clark, the territorial governor, asked for federal relief for the "inhabitants of New Madrid County". This was possibly the first example of a request for disaster relief, which would later become the job of the Federal Emergency Management Agency (FEMA).
In 1993, the seminal alt-country group Uncle Tupelo released Anodyne, their last album, which contained a song called New Madrid written by Jeff Tweedy. The song makes several references to the New Madrid earthquake.

Basically the damage at the new stadium was all of the vendor carts and umbrellas become projectiles. I don't think anyone was seriously hurt.
The folks at the game were watching live radar on the jumbotron as the storm came through.
thanks for the links!
Not for a Braves fan.
Ok, thanks for the correction.
Safe to say then that derechos, MCCs, and MCSs often produce bow echo radar signatures?
Also, the links provided indicate that this type storm depends on low level instability, is it then safe to say that the difference here is jetstream support, or are there other factors that distinguish between this formation of type storm and ordinary supercells? Are the MCCs, et all, in rotation or is this usually confined to individual updrafts within the MCC?
What part does the stationary front play in the evolutionary process? Are there midlevel conditions that favor development of one type or another?
No need to answer all this unless you want to, I know it's a lot and will pick it up elsewhere if need be.
Thanks.
KSDK just reported 460,000+ without power in STL Metro Area. This is not good with the temp going up to 100F tommorrow by late morning with heat index around 114F+.
This could a very bad situation for St. Louis if power not restore before the temp gets up there.
Yes most of the time Derecho events DO produce bow echoes on radar. That is correct!
Sorry for the typos and poor spelling. I better get to bed as I might have to travel to STL tomorrow to get my mom if her power has not been restored. She has a cat and I'll just go up there and bring her and her cat home with me.
