Quake Rattles SoCal Overnight

I thought I was dreaming

Mary, be happy you thought it was just a dream.
If you have friends or family in Southeast Riverside County they have to live with the reality that the overdue "Superquake" could bring down the experimental "jelly-fill" dam on the east side of the Diamond Valley Lake reservoir, drowning them quicker and more violently than the Katrina victims.
Most don't know about this, of course, but those who do are up tight right now because of this week's swarm of quakes just six miles from that dam. They worry that these may be "precursors" to the 'Big One' that seismologists have predicted and they've read recent reports that large quakes trigger small ones on nearby faults --- like the one that runs directly under that East dam.
They will be evacuating for high ground the moment a large quake hits, of course, because no evacuation plan has been set up.(Officials have been amazing blind to the realities, ignored the State Law that requires this.) The ones who can afford it have invented reasons to go on vacation for the next few weeks until these quakes did down.
In 1995 Geological Survey seismologists rated the San Jacinto fault with a 61% chance of a magnitude 6.7 quake or stronger within 30 years. No big deal unless you have family or friends in Hemet, Menifee, Sun City, Canyon Lake or Lake Elsinore.(Most folks in Murrieta and Temecula will be OK unless the west "jelly-fill" dam collapses and no faults were recorded under it, although it does sit on soft ground that could liquefy.)

I live in Valle Vista. And I am aware of the fault line, the higher chance of fire, the possible floods, the pedophiles and the invasion of Los Angeles crap...I get it. I could also move back to Temecula and deal with San Diegos trash, traffic, and the crowded, rude people. Still, Valle Vista is beautiful and I am really happy here. Lots of people are.
Bad things can happen anywhere. You can get hit by a car on your way to the store. You can live in fear on the 'what ifs' and miss out or you can enjoy life.

I think we are living in the last days, look what's going on at the east coast. armageddon is on the way.

10-years on the south end of Lake Elsinore made me keenly aware of the concern of some of my enighbors up through Canyon Lake, Sun City, Menifee, Winchester and Hemet regarding the 850 billion gallons of water that would fill the new reservoir in the late '90s. They knew of the deep fault under the East dam, knew that Earthquake Ladies Hutton and Jones had pointed out that a large shake can trigger another one in a supposedly 'inactive' one like that just six miles away. It takes no great imagination to picture a 20-foot-high wall of water making kindling of south Hemet and then rolling down across these communities at fifty+ mph.
With recent USGS studies reinforcing the warning of a 'triggered' quake and half of the 30 years gone by those residents have mostly sold out to people who don't know about the probability of a huge quake and the potential for another St Francis Dam massacre - or would not care if they did know. They either moved to higher ground or to states along the Gulf of Mexico where the grass is green from rainfall year-round and the Governors are more interested in keeping taxes down and the federal government out than with building fast trains, bird refuges, fish ladders and wind farms with the public's taxes. Nasty humidity but warm and they can have a much higher quality of life for their income.
The past couple of generations of Californians gave away their Eden by not keeping themselves informed well enough to vote intelligently and spend their wealth wisely. Those who take from government now outnumber those who contribute to it so the people who are elected are focused on keeping the 'masses' too confused, too ignorant of planning optios and too racially divided to see through the game of buying voters with their own money.
(A rapid increase in the poverty level is the result of the eternal truth that overspending by foolish, ambitious and/or morally corrupt polticians is doing severe damage to the lowest income people who wishfully think they are getting freebies.)
The Diamond Valley Lake reservoir was wholly unnecessary, just as the San Vicenty Dam raising in San Diego was a fraudulent enterprise by officials who are primarily focused on feathering their nests. The fact that these now pose major threats to the lives of tens of thousands of people who paid for them, due to the likelihood of quakes, makes this planning a criminal activity of public servants who became the masters of we who pay their wage.

Good news for nervous people living in the Valley of the Shadow of two huge dams holding back 400 million tons of water perched high above them in the Diamond Valley Lake reservoir; The swarm of quakes alongside the east dam has slackened, down to just magnitude 2.
The bad news is that there were a dozen quakes nearby on that San Jacinto fault this past week, showing that it is slipping significantly which builds cumulative stress that has to be relieved.
It may be that USGS geologists Kate Hutton and Lucy Jones were mistaken when they published a warning before the dams were built that large quakes can trigger movement in nearby inactive faults like the one under the east dam. After all, predicting quakes for 30 years ahead is almost as difficult as predicting climate 100 years from now.
#9 Nov 16, 2012
Bad news again, another swarm of small quakes along the deadly San Jacinto Fault by the East Dam of the enormous Diamond Valley Reservoir. But even more worrisome is the tiny quake right under that dam along a deep fault that was declared 'inactive' by the builders so that they could move ahead with construction to meet MWD's busy schedule.
That timetable called for creating 'rolling blackouts' in '99 by running huge pumps full time with the excuse of filling this lake. The folks who run MWD from within bank boardrooms also control the energy companies so could coordinate this with 'generator failures' and 'maintenance shutdowns' to manufacture a shortage of electricity during hot weather. This allowed their stooge Governor Davis to commit the State to a flagrant theft of more than $50 billion with long-term contracts at grossly inflated prices.
End result; Hemet-Winchester-Menifee-Sun City-Lake Elsinore residents were blessed with a monster water hazard capable of exterminating them at any time. This distant but distinct possibility comes because there is virtually no possibility they can evacuate fast enough to escape the massive flood when a Superquake on the San Jacinto Fault triggers a slip in that fault, collapsing the 'jellyfill' dam over it,
Of course that tiny quake does not mean they are in imminent danger. But it does tell them that someone lied when that critical fault was described as "inactive". Now they have to worry about what other critical facts were left out of the reports MWD published, and why.
The good news; MWD reduced the level for filling that lake.
But that is also bad news, revealing concern that the long-overdue Superquake could cause a disaster more than 100 times as large as the St Francis Dam failure that came after the same kind of hurry-up planning and construction to enrich a banking-energy-water-land syndicate.

Another tiny quake today just south of Hemet brought me several calls from pverly excited residents of the Valley of the Shadow of the Big Dam".
I pointed out that it was only a mild quiver and several miles from the re-activated fault under the dam. But a caller with more geologic knowledge than most reminded me of the studies by Kate Hutton and Lucy Jones regarding 'triggered' quakes, and wondered if another significant fault may have been revealed by this.
My opinion, for those who follow this issue and know I'm not an expert::
Of course the tiny quake indicates movement (in a relatively shallow fault) And yes, this signifies that a major quake on the big fault three miles farther east could cause slippage in either or both of these and therefore increase the potential for displacement of the dam's soft inner half that could cause overtopping and 'instant' failure,
But MWD recognized these dangers after we jogged its cage repeatedly a few years ago, and reduced the 'full' level to minimize potential for catastrophic overflow. Unfortunately that lower level would not prevent damage from the "rhythmic wave" a large quake could generate, but it would take a "really Big One" to collapse it.

Greetings from Michigan:
As I stare stone-faced at a radar report casting the inevitable humongous red/pink blob of the first lake effect snow storm or the Winter season, I'm seriously considering a move to San Diego, earthquakes be damned! LOL

Good day. A little about who I am. I have been studying earthquakes and faults for more than 45 years. I got started in 1964 as a seismologist for the Air Force. I wasnt look for earthquakes although I did see a lot of them. I was looking for explosions and impacts. When I retired in 1973 I kept at it by building my own seismograph. It worked pretty darn good if I do say so myself. I live in Hollister, Ca. which is known as the creep capital of world because of the Calaveras fault that runs through Hollister that is always on the move. I live about 3 blocks west of the fault and about 5 miles east of the San Andreas fault.
The fault that scares the seismologists the most is the San Andreas and the Coachella Valley segment in particular. The reason being is that it has been more than 300 years since the last major quake occurred on that segment. The last earthquake is thought to have occurred around 1620. The date determined was by trenching the fault. They discovered that the interval between quakes was 220 years.
It is now believed the fault could have a quake up to 8.3Mw. It isnt the magnitude that scares them although it does make them nervous it is supershear.Supershear involves the fault rupture in that it ruptures faster than the S wave generated by the quake. The velocity of the P waves is 5 miles per second; the S wave is around 3.5 miles per second. The velocity of supershear lies in between the P and S waves. These are body waves. The other two waves are surface waves. These are the L and R waves and it is these waves that most people feel and also cause the most damage.
When the quake finely occurs and supershear occurs the LA Basin will get hit much in the same way a boxer delivers a one, two punch. It is believed the shaking could last for as long as 5 minutes.
The L and R waves are low velocity, high frequency waves and they will get the tall buildings to swaying to the point they could go in one direction to far and not be able to recover. The LA Basin and LA itself could become history. The resulting damage and deaths will be unlike anything seen in the US. It could take up 20 years for the LA Basin to recover. There are some who say it will never return to its former glory. That could very well be true. Only time will tell and were running out of time. Take Care Don

didn't feel a thing, go back to sleep people and stop drinking the world if going to end koolaid

Your descripton of the damage that could result is unfortunately accurate, a scenario that politicians and journalists ignore to please the land speculators that dictate their career success through control of our major news media.
We mere public citizens were given a "head's up!" back in the early '90s from editors and TV anchors quoting USGS experts who predicted a "Superquake" within 30 years. But after various online forums discussed the potential of flooding from the enormous Diamond Valley Reservoir that was under construction, the geologists went silent along with the politicians and journalisnts. Job security exerts powerful influence upon the public servants we trust to keep us informed.
The concern of residents living below this reservoir was that they were potential victims of the flood hazard created by dirt dams enclosing this huge lake.(850 billion gallons capacity) The major quake predicted would obviously make the big dams quiver and since the inner half of them would be saturated it seemed likely that this could result in settling that allowed overtopping by a massive wave generated by the shaking. Their fears were aggravated by the failure of local officials to demand an "Inundation Map" as required by State law. This would have shown were floodwaters would flow and so allow new schools and homes to be located in safe areas.
Once again the news media ignored this violation of State law and the matter was forgotten. Local officials did not make up evacuation plans because they had no clue where to direct the public should a dam break occur. So residents wise enough to recognize the hazard made individual choices, either selling their homes at a reduced price and moving to high ground or just resigning themselves to their fate.
After repeated reminders on local and outside forums managers of the dam (MWD) finally recognized the potential for dam settling and "sloshing" of the reservoir combining to create a massive disaster. They lowered the capacity level by 50 billion gallons to mitigate this danger and hopefully this will be sufficient when another major quake occurs in the San Jacinto fault zone.(Over 30,000 homes lie in the immediate path of "raging" floodwaters, with up to a million total as these pour out to the Santa Ana River and head for Disneyland's flatlands, so this is certainly a significant concern.)
Geologists are constrained, by job security and career advancement issues, in their ability to warn us of hazards even when these are obvious. The Boards of Profiteers in major banks have shown great skill in circulating misleading propaganda, manipulating news sources and damaging the finances or reputations of 'noisy' activists and the public servants who agree with them.
Having escaped the latest "Apocalypse" we can once again think a bit about unlikely but quite real potential disasters, hidden dangers that deserve serious consideration.

"The quality of mercy is not strained, it droppeth as a gentle rain from heaven." but 'tis said the Lord helps him who helps himself.
Residents of Riverside County have, collectively, been too disinterested to help themselves by informing themselves about the potential for meeting all water needs with their rainfall.
If they knew how quickly and cheaply this could be accomplished the simple human greed that drives us all would make them refuse to pay extortion to persons who steal someone elses rainwater for them.
We can just hope that a 'Superquake' will not happen and our costs for water-energy will not go up. Or we can make simple preparations in case a quake does happen, and elect politicians who will reduce our taxes and utility costs by instructing our public servants to save our ample rainfall.
Informing ourselves adequately is the first and most important step.

Well,thanks for scaring the begeezes outta me. I had thought since I'm outta the way of the Salt Creek flood plain, I was good. Now, I'm thinking not.

Geez: This website < http://sdcounty.ca.gov/oes/docs/DRAFT_COSD_Da... ; shows San Diego County's two dozen risky dams and at its top where thousands of acres in Temecula and at Camp Pendleton would be flooded if the west dam of Diamond Valley Lake collapses.
The Salt Creek "flood control" project was a land developer scam pushed through to legitimize building thousands of homes in a floodplain that will be overrun when a major storm bumps up against Mt San Jacinto to drop a 100 billion+ gallons of rain on your watershed. The channel will not prevent massive flood damage if the east dam of Diamond Valley reservoir collapses during a major quake. Evacuation is not an option, the roads will become instant parking lots when a major quake hits and people who know about that dam's faults try to evacuate.
State Law says land buyers must be notified if a property is in a flood hazard area of a State-approved "inundation map". Your friendly local politician should know if your family and schools are in the path of destruction from rampaging floodwaters pouring out of Domenigoni Valley if a major quake in the San Jacinto fault zone triggers movement in the fault under the East dam.
Not likely he'll be able or willing to explain why you help pay more than 100 million in taxes to get rid of rainwater that could keep all reservoirs full.
