HALT is a CERI seismometer.

folkworm.ceri.memphis.edu...

Doesn't show a 9.9 on that
must have been a typo error eh

Had a look for RGRS which had 7.9 too, I have this, RGRS CSC 32.9075 -80.1942 -52 Roger Stewart
and day 236 , what the heck is this at 00:06
www.iris.edu...

theres a green flicker at the said arrival time of 17:53:38.73 for the Peru quake, but it looks nothing like a 7.9

Finally got onto Peru Sismos Sensibles, 7.0ML

Hey Yo Bob - You sure your at home? Appears to me, your on a -- umm -- on a roll mighty riddled these few days = what's up with that

Things sure are hincky! PC giving me problems here at the moment - need to post something on the Yellowstone Thread (insert bowing icons here if I knew how) but having issues once again with getting a screenshot to upload here - keeps asking me to login - drats -

Anywho - don't have lots of time of late - someone please make a post in which ever your favorite hurricane watch thread - the time is now to prepare - appears i'm gonna get blasted (dam the bad luck, I just spent the last 4 days trying to get the shale/gravel back on the 1/3 mile long driveway - good thing I own a york rake) - - -

Did a small google search on Edgar Cayce and the 37th - search revealed: No Returns ---- BUT- Let's take a look at the New Madrid Quake and the Great SF Quake - Odd No?

Water does lubricate faults. But it's not the same thing as lubricating an engine with oil. The water travels through the fault and causes erosion. It's superheated because of the pressures and heat underground. It carves channels and removes material. It's kinda like glaciers.Glaciers have supercooled water that flows down through the glacier until it hits the crust. It then slices along the bottom like a large waterfall. The glacier is actually moving on a superthin-cooled layer of water. You can think of water in a fault in reserve. It moves through the fault and destabilzed the fault until enough resistence is removed. It technically doesn't slide along on the water making it more slippery,

Damn, I forget the name of this type of sand, that contains water, and they find it in California and scientists think this material lets those particalur quakes slide.

If you throw cold water on a rock you will crack it. A sudden rush of cold water that runs into a fault can cause it to crack. That's what can happen at Yellowstone. When water can breach one part of the geyers plumbing and migrates and hits hot rock, there is an hydrothermal exposion underground causing an earthquake. Or more likely a swarm.

Water does all kinds of weird and whacking things depending on its state.

Don't know a lot on the subject,but what you said about water had me thinking about the East coast area.Are there any known maps of underground cave system that runs along the coast out in the Atlantic?And if so is it possible for Hurricane Irene to push water deeper into it?Maybe causing another Quake..Don't know if it's even plausible,just an idea..

ok..so maybe this is nothing...but I am sitting at my PC with the windows open in my room...I am in VA..there is a smell that is nasty coming in my windows....I mean terrible! I am in the county, with few neighbors..but it stinks like rotten eggs (only thing I can think of). It's BAD!.

I am hundreds of miles from the quake in VA yesterday...South West of it...but I am on the same latitude line as all the quakes over the past few days, from CA to VA, in the USA.

I have had music pumping through my speakers all day on my PC. Not sure of any noises in the area...but the smell is terrible...never had this scent before....WTH??

It could be a number of things -

Are they fracking in your area?

1) Volcanic emmisions (No, no volcanoes in the area)
2) Fracking emmisions - tbd
3) Offshore winds coming your way from the hurricane (I don't think that is it as the winds are in that direction yet!)
4) Nuculear blast residue - tbd

Do me a favore - check to make sure that you turned all the burners off on your stove and grill - you might have a gas leak or you are getting low on gas and may want to have it filled before the hurricane gets here!

Another jolt hitting Virgina now...not sure but looks like around a 4


4.5

earthquake.usgs.gov...


And that would be in the typical range of aftershocks for a 5.8 main shock.


And MAN the USGS got that up fast, wow. Unusual.


And just for the record, that measured about 800 microns/sec at US.CBN- with the quake very close to the 5.8.

Just felt that one. In in southern va, 20 min from the epicenter of the last one. Definitely felt that, but not as bad as before. Nothing on USGS yet though.

edit to add that it is now reported on USGS as a 4.5


Yeah, I was expecting aftershocks, but certainly not ones I could feel. This is all quite a new experience for me!

I just read on glp that they are smelling rotten eggs in tennessee right now, too.

Could you please explain the significance of that for me? Thankx!

Know how you feel... we've had over 7,500 aftershocks since Sept's 7.1 here in New Zealand They're calming down now and I am beginning to miss them!!

It's a measurement of peak ground velocity at the seismic station itself, which some of us are monitoring live right now. I report it so that we can have some kind of reference when guessing magnitudes of future quakes in the same rough spot.

Notice this time I got a little closer- cause of past references. I said 4, USGS says 4.5- and keep in mind that can still change. Often does even after they initially post it. They review the quake parameters and often make magnitude changes even after posting it on their site- because other information becomes available.

... my bad. Safeway had a special on deviled egg potato salad and burritos. Was too good to pass up.


I'm going to guess after this 4.5 in Virginia that Colorado will get one around 3.8-4.2 in the next couple hours.

who just imagine if VA has anywheres near that many.

the difference? which of the two are around the known, predictable Line of Fire??

reply to post by MoorfNZ


WOW! 7500? Thats incredible. Im sure the original had you jumpy for a while. After yesterday, I can definitely say I dont wish to experience anything stronger.

reply to post by TrueAmerican


Thanks for the reply. So how many more aftershocks do you think we will get? (At least ones we can feel) And do you think there is a possibility of an aftershock that is stronger than the original quake?

An aftershock stronger than the original mainshock would then be classed as the mainshock and the 5.8 a foreshock Any quake following the mainshock, and smaller than it, is an aftershock and are classed as such until quake activity returns to normal, background levels.

Thank you for explaining that! I sure hope there isnt a quake stronger than yesterday. The people around here would not take that well, this being quite a new experience to everyone. The stories I heard yesterday were sometimes funny, but definitely laced with panic induced fear.
