Nope, just a business trip.
Ah, twisters are nothing.
I have only seen a funnel once.
People hype up the threat.
There is a greater chance your house will be struck by lighting, twice, than you will even have a tornado do minor damage to your house.
If you key on the other maps referenced in earlier posts to this thread say the yellow squares are yesterday. The date /time is shown at the top of the graphic.
hey, they chose to live there.
Please add me to your ping list.
Thanks.

Even in the middle of Oklahoma the mathematical odds a given acre of land will experience a tornado in the next 100 years is some astonishingly low number....saw it a couple times but haven't been able to fidn a source.
All sorts of people use natural events all the time to further their agenda; envirowhackos, religious apocalyptikooks, anti-government conspiracy nuts, etc.
Art Bell once described the 10, the 11, and the 12. We haven't had a 10, yet, but entire cities would be devastated. An 11 would pretty much destroy a state. A 12 would flip over a continent.
> ...if the Golden State fell into the sea we Phoenicians could get the the ocean a lot faster.
OK. Let me set you straight, here.
California is not falling off into the ocean, those West of the San Andreas are simply shoving off on a long, slow Alaskan cruise.
Those East of the San Andreas, on the other hand, are going to sink into the Atlantic, which will bring new meaning to location nameas like "Lower East side".
Good luck. Cali is beautiful, and I hope you stay safe.
The scale is open-ended but it's physically impossible to have an earthquake above 9.5 on Earth caused by a fault; to get above 10 you're looking at a fault that would circle the earth and none of those exist.
Really really large asteroid hits could conceviably cause a 10 earthquake but in those situations the earthquake from impact is the least of your problems.
It's not possible to have above an 8.3-8.5 or so physically within California. You could have a 9-9.2 quake on the Cascadia subduction zone offshore Washington, Oregon, and Northern California.
Do you have a reference picture which shows that plate and where it runs along the coast ..??
I just use the USGS world picture because the pacific rim facinates me (being part of it).

Actually the margin between the Pacific and North American plates extends from just offshore Calfornia all the way to Utah; the San Andreas contains most of the motion, but not all of it; it's shared among a variety of faults and actually the entire west is sort of being stretched out and moving NW, less and less the farther east you get.
And pretty much all geologists are in agreement that the San Andreas is gradually becoming less and less of the primary boundary and that it will shift to run up east of the Sierra Nevada into the State of Nevada.
some "expert" on CNN last night said there was a "minimal" about "10%" chance another large quake would hit.
I just checked out the USGS site....a string of 3-4.7 earth quakes are everywhere...im not familliar, is this common?
Good call: You are right.
The less specific anyone is about quake prediction the more of an expert they are.
The more specific they are, the greater the chance they're a charlatan or kook.
You mean California or worldwide?
The 7.2 quake offshore California is going to be cranking out aftershocks for MONTHS....its aftershocks are pretty normal so far; typically they'll decline slightly week after week.
Worldwide, lots of quakes are normal; there are an average of 4 5+ magnitude quakes worldwide every day, and an average of over 35 magnitude 4+ quakes worldwide every day (that's a rough estimate because there are still enough gaps in worldwide seismic networks to miss some 4=5 magnitude quakes; all the 5+s pretty much get recorded.)
There are very, very, very few F-5 tornadoes.
Can you add me to your ping list also, bd476? If Brads Gramma gets to be on, I wanna be there too!!!! *G*
