Quake Watch 2012

Regarding the Salton sea recent quakes, i believe its over due for a 7 or above quake... wiki says every 180 years, and the last one was around 1700 or so

The Salton Sea and surrounding basin sits over the San Andreas Fault, San Jacinto Fault, Imperial Fault Zone, and a "stepover fault" shear zone system. American researchers determined that previous flooding episodes from the Colorado River have been linked to earthquakes along the San Andreas Fault. Sonar and other instruments were used to map the Salton Sea's underwater faults during the study. During the period when the basin was filled by Lake Cahuilla, a much larger inland sea, earthquakes higher than magnitude 7 occurred roughly every 180 years, the last one occurring within decades of the year 1700.

Yeah, THAT jumped out at me.. some major stresses there. Or that lake is an extinct volcano...

Now worried it just went quiet......

Something is building up.

I'm not in favor of stopping political posts, I'll just try not to make any.

Re Salton Sea area quakes:

We interpret seismic activity in the active spreading centers of the Salton Trough to indicate 1) a magmatic intrusion in the lower crust beneath the active Brawly, Cerro Prieto, Imperial, Elsinore, and San Jacinto fault systems; and 2) fluids in the upper crust that have been released from that magmatic body. The absence of a magmatic body and fluids at the location of fossil spreading centers along the Sand Hill and Algodones faults ndicated by little or no seismic activity in those areas. We show several lines of evidence to point out that both melt and fluids related to the seismic activity.

The Role of Fluids in Promoting Seismic Activity in Active Spreading Centers of the Salton Trough, California, USA(2.33MB .pdf)

What the paper is about is that it seems that seismicity in this area is due to magmatic intrusion and the analysis of relevant data to support that conclusion:

We associate seismic activ-ity with the presence of a magmatic intrusion beneath the active spreading centers and with fluids derived from this intrusion. Several lines of evidence support the existence of magma intrusion and fluids: 1) low velocity and high Vp/Vs ratios in the lower crust as shown by tomography and receiver function analysis; 2) low amplitude mag-netic anomaly in the location of active spreading centers attributed to the fluids and/or melts; and 3) a high ampli-tude gravity anomaly that underlies the active spreading characteristics of the inferred magma intrusion can be recognized over a distance of 70 km in a NE-SW direc-tion along the fault zones of the active spreading centers (Figure 9).

The Cascadia OBS network has had one round of data recovered, but the navy has first crack at excising a tiny bit of data, then it gets Q & A, then finally get posted at the IRIS DMC for anyone who wants to look at it.

This describes the sequence of experiments: cascadia.uoregon.edu...

We talked some today about making a good catalog of the earthquakes offshore N California, Oregon, and Washington so that we can better understand the region that generates the Cascadia M9s.

You mean a new catalog that incorporates events cross correlated with the new OBS data and then recalculated for locations, mag(s), and focal mechanisms?

And that brings up another thing: Just how much recalculating would be done using that new OBS data? Have you guys talked about that much? I know you said that was all still being discussed, and remained unclear, but just wondering if that hazy vision has cleared up any yet...

Thanks for the link and updates.

reply to post by TrueAmerican


It's clear that we would like a good map of seismicity offshore, but not clear exactly the steps worth doing.

One could imagine:
1. Locating precisely events during the OBS deployment.
2. Tuning locations dating back as long as we have some data, the late 1960s, with improved velocity models (really improved station corrections) built from doing chore (1).
3. Cross-correlating all known events against the time interval during which we have continuous data, roughly a decade or so, to find more events that we had not previously spotted.
4. Tectonic interpretation of the resulting improved earthquake catalog.

Such a project would involve both the California and the PNW catalogs, and funding and available manpower is not obvious, so it is just discussion so far.

Well sounds like you've got an excellent basis for a funding proposal to the NSF, or even the American Recovery and Reinvestment Act. That might be a not-so-obvious funding source, and they have funded other special studies like this one:

www.dnr.wa.gov...

The question is, can the need to examine that data exceed other needs in a climate of tight spending and budget cuts... Oops, getting political again. Funding, that nasty nasty beast.

What about proposing to a place like Berkley that students or interns do the work in exchange for academic credits? Perhaps a special electives class or something?

I am just real curious to see to what degree that new OBS data constrains the existing data, and particularly, depth and location data. I don't expect magnitude data to change all that much.

Fun Fact Number 1
They have geothermal product plants on the Salton Sea.

Fun Fact Number 2

The Salton Sea was an accident. Like an unplanned child.

One day, somebody will spread my ideas and I will then be content. It's so hard, the waiting. Oh Puterman, did you notice I didn't sully up your Santorini threa with my wild idea that I have seen with Abraham's eyes. I'm proud of myself. I'm learn to let go of things. I don't like it. But it's intregal to survival.

So. I have always thought that rain had something to do with the San Fransico quake of 1906. There is a great film taken on San Fransico Trolley Car which shows the wet streets and swollwn puddles. Part of San Fransico was liquified. I think water did more than just help make the earthquake more devesating. And even if I could prove it lubricated faultlines, it wasn't the whole story no. NO. Because the Salton Sea is part of the story. Or rather, the breach in the Colorado River caused the earthquake. In 1905, there was heavy rains which flood large areas and to make a long story short, it ended up in the Salton Sea. The water cycle for the years 1905 and 1906 show heavy precipitation. This vast movement of water and it's sudden change in course shifted stress loads on various faults. The flood of 1905 set off a chain reaction which shifted the wieght all over the state of California. This change along with masive rains in San Fransico destabilized the entire region.

The Salton Sea made one side of the teeter tatter too heavy and San Fransico pops up.

The filmakers were the Miles Brothers. Me mom is a Miles.

but the navy has first crack at excising a tiny bit of data

ex·cise 2 (k-sz)
tr.v. ex·cised, ex·cis·ing, ex·cis·es
To remove by or as if by cutting: excised the tumor; excised two scenes from the film.
[Latin excdere, excs- : ex-, ex- + caedere, to cut; see ka-id- in Indo-European roots.]
ex·cision (-szhn) n.

Data is being removed? Are you able to explain this? A simple no will suffice if you are not.

FYI my GPS page has just been updated.

Additions have been made for the complete European reference network and for NOANET GPS (Greece)

If anyone has additions for this page please let me know.

The navy invests a lot in making various boats hard to track, and there is no point broadcasting their carefully recorded signatures.

reply to post by JohnVidale




Obviously they can be tracked then
