At the Salton Sea, a warning sign of the Big One?
Swarm of small quakes in the Salton Sea area has scientists wondering if
faults there are transferring energy to the larger San Andreas, where a
major temblor could occur. http://tinyurl.com/cgpqym |

Any earthquake could be a warning sign of the Big One.
JMHO! |

More likely to possibly be a precursor to something like the El
Centro 7.1 quake of 1940 or even the two 6.3 quakes of 1913.
Ultimately, I suppose, any quake on some place of the SAF resutls
in a shifting of stresses that could ultimately lead to a quake
on other parts of the fault.

Several VERY competent local seismologists say
that the area is overdue for a quake in the high
6s or low 7s.
Should shake San Diego well, but not do any major
damage, but if I lived closer, I'd be more concerned.
I'm MORE worried about having to buy someone a
bottle of Scotch IF this is a bunch of foreshocks!

Wouldn't it be interesting if all these water main breaks in So. Cal were a
sign of shifting in the earth's crust in this area?
A typical scenerio might be:on New Years Day when TV cameras from all over
the world are trained on Pasadena and the Newport Inglewood fault breaks
loose and/or...
during one of the 2009 LA Dodgers & LA Angeles (freeway) World Series
baseball games when TV cameras from all over the world are trained on the
ball field and the newly discovered fault that runs under Wilshire Blvd.
breaks loose and all hell breaks out.

Not really.
The pipes break because they're old.
If they were breaking in some pattern that could be seen,
maybe it would be different. |

We've been there, done that. 1989 World Series, Game 3,
Candlestick Park, San Francisco.

And perhaps because of the drought-inspired watering restrictions.
There is a suspicion that restricting lawn watering to certain days is
causing larger flow and pressure swings in the pipes, which is causing
them to break more readily.

Same thing happens even in wet years.
The problem is worse now because maintenance has been delayed in many
areas.

All the water mains breaking have nothing to do with the shifting
crust. They are O L D (the water lines), some of them go back to the
1902 era. They are for the most part lead connected double flange and
riveted 60-72" transmission lines with 24-36" mains. Put it this way,
these water lines were put in prior to the first car ever running
along in Los Angeles. Imagine L.A. without any cars ! ! ! That was a
long time ago. Don't try to read anything into the main breakage that
isn't there. The DWP also has a bunch of totally ignorant idiots
called engineers that think they can turn lines off and on at their
whim. So what happens? Coldwater Cyn. blow out. Victory Bl. blow out,
etc. etc. The Crown Jewel was the collapse of the headlead going into
the Aquaduct in Owens Valley where they vacuum collapsed 6.5 MILES of
96" pipe causing $18.25 million damage. Way to go EAA. The dumb
ass-bite engineers tried to blame it on faulting, but I was able to
show that it was a case of total stupidity. They shut the gate too
fast. Faulting wasn't even close to being the cause. |
