The largest an M4.7!!! (Most of them microquake level)

YOU GUYS ARE GOIN' DOWN!!!!!!!!

that quake in Northern CA for 9/23 looks like it occurred up the Feather River Canyon, (highway 70) not too far from me as the Crow flies...

personally, I'd rather see a bunch of little quakes like that than one giant one, because its my understanding that they release pent up energy along the fault line and lessens the potential for damage in so doing.

here's a link to the Oroville Dam seismogram and here's the pic:

David, you're inciting panic around the globe with your "Chicken Little" outburst, now go sit facing a corner and play "The Second Time", "When I See You Again" & "Docklands" back-to-back 100 x's in a row until you learn not to react in such a flagrant manner.

Shame on you...

a 4.7...

...a Ralph's Market 18-wheeler going down Rio Vista Avenue causes the house to shake more than a quake of that magnatude. And, remember, you live in the same block where the multi-million dollar homes just slide down a hill for the heck of it.


And to those in Rita's path....Get to high ground!! Be safe!

Do you live in Rio Vista? the Rio Vista with Foster's Big Horn? Quaint little town that...isnt that the place where that misguided whale finally got turned around and went back out to the ocean? Ive seen the plaque ya know...and Ive been in Fosters (not a place for the PETA people for sure) Thank God the days of the Great White Hunter are dead (except for a local GOP in MY neck of the woods who regales our town with testosterone laden recounts of his exploits woo. hoo.)

As a sidenote, there's a phenomenon now being studied known as "stress triggering." The upshot seems to be that all earthquakes -- large or small -- relieve stress at some point along a fault. But through a complex series of processes, future quakes (aftershocks or mainshocks) can theoretically be triggered along the fault -- nearby or distantly -- or even on adjacent faults. And as Brian says in his FAQ, it would take thousands of small quakes to spend the accumulated stress of a major quake (in a correlation that depends on the magnitude of quake).

Look at the two humongous quakes in the Sunda Trench within the past year -- they occurred within three months of each other & within only 110 miles of each other.

I recommend this book: it's cheap, currently in print, etc. It's called "Earthquake Science: What We Know & Don't Know About Earthquakes" by Susan Elizabeth Hough (a seismologist with the USGS in Pasadena).

O.K. guys.....this may be the last time I'm able to get online because the worst of it should be coming late tonight. They've 'predicted' the eye to pass straight over Port Arthur, Tx which is about 50 min south of my house. We're away from the storm surge, but are going to be on the dirty side of the storm. We've prepared as much as we can...it would've been impossible to get on the road yesterday. Every northbound road was packed, with all the busses with evacuees from NO on top of the two million people trying to get out of Galveston and Houston, many people are stuck on the side of the road, without gas. They're trying to get gas trucks from DOT to them to get them on their way.....but those poor people who took the 'back roads'....I wonder how they'll get help. So, Please pray for us.
