We conclude that our findings support the hypothesis that tremor results from local heterogeneities within the slipping region that accelerate to high enough slip speed to radiate seismic waves. ...
If ETS events can trigger or evolve into dynamic megathrust earthquakes, locating active slip via the tremor may prove to be a powerful method for monitoring subduction zone activity.
We suggest that the migrating tremor records triggered slow slip of the San Andreas fault as a propagating creep event. We find that the triggered tremor and fault creep can be initiated by distant earthquakes as small as magnitude 5.4 and can persist for several days after the seismic waves have passed. Our observations of prolonged tremor activity provide a clear example of the delayed dynamic triggering of seismic events. Fault creep has been shown to trigger earthquakes10, 11, 12, and we therefore suggest that the dynamic triggering of prolonged fault creep could provide a mechanism for the delayed triggering of earthquakes.

Have you seen this?

By teaming what is called "prolonged triggered creep episodes and their effect on major slips" and recent GESS results, the research is phenomenally convincing; a major event is at the doorsteps of southern california, again, "imminent". I stress, timing is everything, and thus why there is no current public data. New information if pouring in daily, however we're moving in the wrong direction.

Minutes from a closed door that was forwarded to me, based on recent information connected to earlier posts
"A 7.0 quake in the greater Los Angeles metropolitan area would potentially kill millions and cause upwards of $1 trillion in damages,"
I shouldn't be saying this but there has been new studies that are not yet published. The risk is "imminent".
I'm sorry I can't print more.
Stay alert.
There is some intriguing research about whether large earthquakes are associated with ionospheric changes caused by electromagnetic signals released by the crushing of rock crystalline structures. If so, then this might be a mechanism for major earthquake prediction. One of the primary researchers in this area is Friedemann Freund, of NASA Ames. He has written several articles introducing the concept of ionospheric and atmospheric changes as earthquake precursors:

They are feared because they seem to strike so unpredictably. Yet, for centuries, and even millennia, people living in seismically active regions have noted premonitory signals.

Are we being told that they're listening to the earth and are picking up something that tells them about when it's about to snap and combining this with the InSAR/GESS imagery to tel them where?

You know, I didn't want to say anything but I lve got to admit when I went back and reread the posts as a whole those two lines stood out like they were highlighted in neon.
And this was before anyone said anything.
Make of that what you will.
I will add further that I thought it odd that we were told to "read between the lines" and them there was a get specific declaration

He's only posting in the Arkansas thread, that is important I'd say, ant the sentence with millions killed and trillions in damage may not necessarily refer to LA. Good thinking Jadededit on 9-9-2011 by SunnyDee because: (no reason given)
But now the data are flowing in like hot lava. Scientists from Greece, China, France, Japan and the United States all presented findings at the recent AGU meeting that support the possibility that ULF signals may precede earthquakes.
Twelve days before the Loma Prieta earthquake Fraser- Smith's detector recorded a large signal. The signal remained high until three hours before the earthquake, when it shot up even further. "The signal was off scale, 20 to 30 times bigger than what we usually measure," Fraser-Smith said. "We nearly shut down the Corralitos system because we thought something was wrong with it." Then the earthquake hit, disabling the system for eight hours.

Well,take a look at this.
I have holding on to it for some time.
Maybe it might help.

Almost forgot about this stuff.
What I find intriguing is the satellite imagery of land surface temps fluctuating rapidly.
