Parts of Washington and Oregon are in the midst of silent earthquakes this week. You can't feel this so-called "slow slip" quake and it doesn't cause damage. Still, scientists want to learn more about the recently discovered phenomenon.

STUDIO CITY (CBSLA.com) — Authorities on Monday investigated widespread reports of a foul odor detected across the San Fernando Valley.
Shortly after 5:00 a.m., a “rotten egg-type” smell was reported “widely across (and possibly beyond) the north San Fernando Valley and Foothill communities of Los Angeles”, according to Brian Humphrey with the Los Angeles Fire Department.
No illnesses or any specific hazard has been associated with the odor, Humphrey told KNX 1070 NEWSRADIO.
The sulfur-type odor — which Humphrey said “appears to be organic in nature” — had been reported as far west as Simi Valley and as far east as Cathedral City and Perris in Riverside County.
While officials worked to investigate the source of the smell, officials did acknowledge the smell could be affecting a wider swath of Southern California.
Stephen Harrison with the National Weather Service office in San Diego told KNX 1070′s Vytas Safronikas that whatever the source or sources of sulphuric odor, wind currents have been moving in an east to west direction from the Salton Sea into parts of the Greater Los Angeles area.
“It’s always possible to get some kind of odor coming from the Salton Sea up through the Coachella Valley through the Banning Pass and into the Inland Empire,” said Harrison.
Los Angeles Unified School District spokeswoman Monica Carazzo said the odor is affecting schedules at some local schools, including Osceola Street Elementary.
“Some schools are implementing a rainy day schedule, meaning that once kids get their lunch, they go inside of the classroom, recesses are inside, that type of thing,” said Carazzo. “But that’s school by school.”
Residents do not need to call 911 to report the odor unless they are experiencing a medical emergency, Humphrey said
I figured out the web address for the imaging of the Farallon from the ARRAY....
Don’t have the 3-D reader though but I assume a is at it’s deepest point then to c the hightest.

If that be the case, its disintegration would happen evenly across all surface areas exposed to the mantle.
Looks like the northern leading edge lines up well with the Appalachians?
Right the farallon is near the mantle and North American plate is not floating on top but anchored to it...
Now the farallon is dense almost as dense and cold as it could be...
On those images you can certainly see the relationship still to the Subducting Cocos. Which for today has bearing on our discussion.
I came across a few other ARRAY pdf’s regarding it...I will post my conclusions in a few days...
Looking at the images you've posted here, my gut tells me it happen pretty darn quick, geologically speaking. Turning the napkin over and using a guestimate rate of 1 CM of movement per year, equals only 6 miles of travel every thousand millennium. I don't think even 22 miles of solid granite could withstand a million years of exposure to the mantle; but I'm probably wrong. ;)
If an even pattern of deterioration is discovered along the plate's entire length, resulting in a uniform thickness, I don't have to tell ya what that indicates; except maybe we just don't understand how it got there in the first place.
As always, I will be looking forward to what ever you come up with! :)
Not sure I uh...support that theory....lol
Time to move the family to the vacation cabin in Otisburg.
Another calm before the storm?
Excerpt: Wiser Now: Is there a hierarchy or sequence of geological events that will signal the start of an ELE? Alvin Conway: “The planet’s magnetic field strength declines, there is magnetic polarity deviation or migration, earthquakes and volcanic eruptions increase, there are changes in ocean temperature and salinity, and the climate basically unravels. This is underscored by an expansion of magma and rise in convection in the planet’s mantle. The earth’s crust experienced the most violence in the Pacific Ring of Fire from catastrophic rupturing when there was a magmatic expansion of the planet. As I wrote in The 7th Protocol, the first time the planet had a magmatic expansion, the fountains of the great deep were broken up and geysers of hot water destroyed the world by a flood. The rupture was very pronounced in the Pacific basin, which is why the underlying geology is so fractured, and why the region is now so seismically and volcanically active. Another massive fissure occurred along the Mid-Atlantic Ridge, which almost cracked the crust of the planet in two. The first magmatic expansion released the fountains of water from the deep. The next expansion will unleash the magma from faults, cracks, and plumes already present in the crust. Volcanoes are erupting en masse, and will continue to do so to dissipate the build-up of thermal pressure in an attempt to prevent a catastrophe. If the planet’s heat cycle cannot be console by planetary geologic processes, the spectrum tilts toward an Extinction Level Event (ELE). Consequently, volcanoes also are our first telltale sign that something has gone awry with the planet. We’re witnessing evidence of another magmatic expansion across the planet with near simultaneous ground inflation occurring from magma intrusion at Yellowstone, Long Valley, Uturuncu in Bolivia, El Hierro in the Canary Islands, Santorini in Greece, Marsili in the Tyrrhenian Sea, Katla in Iceland, and the ground around Mt. Fuji in Japan. These are the early warning signs, along with increased seismicity along tectonic plate boundaries (especially in subduction zones), that something is amiss. No part of the planet will be left unscathed from these changes.” – Wiser Now, October 2012 – Earthchanges coming, Ready or Not – IPAD Mag APP

Thanks, I was just reading about the “quiet rumbles” and watched a video on the Cascadia fault. (just one hour ago).
Yeah I looked into that a few years ago....that have some kick-ass monitors there and have been waiting for the next swarm to start...
They should get some quality data on this episode for sure!
Just FYI - rotten egg smell is due to hydrogen sulfide - reduced sulfur basically commonly found in hot springs, geysers, and volcanoes. It is not normally a product of decomposition, which are more biogenic amines and ammonia. I would say baring some sort of industrial accident, that hydrogen sulfide gas is likely geological in nature.
Hmmm, maybe our sixth sense at work here? ;)
I've researched tidal effects and while far from conclusive, there seems to be some sort of minor connection. I think it may be some other cycle that involves attraction, the core, inclination, moon and sun and maybe even position of internal structure.
maybe :)
Lot of continuous shaking going on after that 6.0. (on the seismocam). They changed the lines again from yesterday. GRRR, makes the cycle of 30 minutes to close together.
There is now a 6.3 north of Australia... Making up for nuttin over M5 on the 6th it seems.
yesterday was eerily quiet.
