Quake Watch 2012

So I'm perusing through usgs.gov. Here are quakes in the last hour, in red.
earthquake.usgs.gov...

Northwest, only abouts a one. I shouldn't of felt that. But I felt that Oklahoma one, sometime back, and i should'nta felt that'un either. But then someone in VA said they had felt the Oklahoma one.

All the helicorders in MO. are showing something is giggling. I can't find Marked tree. Where are you finding that one?
Sorry, that question was for Berkleygal.
'
Found it!!

Thank you, I found it. What ever it is, it seems to gaining a little speed again

I"ve been watching the helicorders in MO. Stahl farm, one of them. Thats where Im seeing something ramping up.

seems we are back to background seismicity for NZ

15th Mag 5+ for 2010
4th Mag 5+ for February (all in the North Island BTW)
that one 26km NE of the last one on the 8th Feb

I was expecting something 4.8ish for Cook Strait next, maybe those 4.9's at Wanganui and Sth Taranaki Bight on Sunday and Monday took the stress off CS.

PM, berkeleygal or anyone. Im trying to understand seismic waveforms. In the below waveforms from Huckleberry Mtn, doesnt the below indicate seismic activity. And if so why does it go on for so long and why is it not recorded in EQ maps.

Which seismo is this? Closest i can find to HM is this one which is showing the same signals (sort of) YMS.WY..EHZ.2012.054

Storms in the area? MCID.WY..EHZ.2012.054 or problems YPP.WY..EHZ.2012.054

Is it very cold around YNP? These seismos are all sent by microwave (or at least were) and there can be transmission problems from icing. LKWY.US.00.LHZ.2012.054 is a satellite seismo and is not affected the same, and basically is showing nothing.

These were supposed to be going onto a broadband connection sometime but I have no idea if that has happened yet.

What is it that you are looking at? Is it the big 'splodges' on this one?



I can pretty much guarantee you that is trains. I don't know where the marked tree seismo is, but I am assuming somewhere in Marked Tree and there is a double track railroad runs through the town. Looks like some heavy stuff going through in the middle of the night.

The sensitivity is only (I think it says) 28.67 mV which is very sensitive and I query why thy would have it set that sensitive when there is so much noise in the area.

Thank you for looking at this. The more I was checking other sites, I was kinda thinking it might be something manmade. I'm still learning how to read these things. I will be doing more homework tonight after work, but for now I must go.

Thank you again. I appreciate all your patience with someone like me who has alot of learning to do.

I just read this article and wanted to share. I am sooooo nice... I know.

The article is from seattletimes.nwsource.com...

It talks about the Japan quake and the fact that if a similar quake happened in the Cascadia Subduction Zone it would leave a lot of cities in ruins. I think we knew that already but I guess now they have data to back up the claims.

I'll get it by December

Hey ya'll, seems USGS is adding more EQ to the NMSZ list; check the ones before the 4.0 ....err 3.9....



That's 9 EQs. Five of which are before the 4.0. Maybe that helps to explain why all the helicorders were so wonky.

Which seismo is this

Thanks PuterMan. The reason Im interested in that area is because of whats happening north at hood and rainer and possible magma flow. Below is showing where the first waveform was from and it's proximity to Mt. Bachelor, Broken Top and the Three Sisters, center of historical volcanic activity in the CSZ. Note Mt. Hood activity.

And this is north showing both Hood and Mt Rainer activity.

And these are recent waveforms for first hood and then rainer. Does any of this look like magmatic activity to anyone.

hood VLM
rainer STAR

in there;
"Some geologists argue the magnitude-9 quake 300 years ago was simply average and that the Northwest has been slammed by quakes twice as big in the distant past."

Wot a load of codswallup, there is no such thing as a Mag 18

maybe 10's of millions of years ago when the earths plates were forming into their present shape perhaps, before the North American continent even existed in its present form, and 50% of the crust was molten lava.

I didn't read any more after that.
Its scaremongering by the journalists

Thats what I was watching last nite and couldn't figure out why they weren't posting them.
I have to learn how to take pictures of what I'm looking at (along with a lot more).

I have 3 computer savy teenage boys and I can never pin one down to teach me.

This post was in regards to the MO. add ons. SCGrits.

Jeez, sorry so goofey right now just got off work.


If you go to the stahl farm, MO and the other two helicorders, you can see they just had another one. Just like last nite, things are giggling in MO.


It also looks like we have alittle action on the Hopedale,il helicorder. I think we got something brewing here on the New Madrid.

Actually, it is a logarithmic scale. Each increase in 1 is equal to 10 times. I'm pretty sure that's how it works. That would mean a magnitude 10 is ten times as strong as a magnitude 9. It is quite possible that there has been an earthquake twice as strong as a magnitude 9 because that would be less than magnitude 10. That's how I would understand that quote. A magnitude 10 would be 100 times stronger than a magnitude 8.

PuterMan, I live close to Marked Tree, although I've not been there for several years, so I can't tell you where the seismo is located or about any railroad tracks.

I can say that it's been extremely windy today, enough so that the windows and doors are constantly rattling. The gusts are in the 40-50 mph range and higher. Would that be the cause of the odd graph shown from Marked Tree?

reply to post by phoenixlights321


Yes you are absolutely right
I didn't think it through.

so the calculation, based on energy released would be;
one Mag 9.0 = 476879138.377 TTNT
add Mag 9.0 = 476879138.377 TTNT
added together = 953758276.754 TTNT
= Mag 9.20067 = 953703385.116 TTNT

Given that, I wonder how many people who don't normally bother about such things thought the same as I did?

why didn't they just say 9.2 instead of "twice as big" which may confuse people

Hi Guys

Last Night excactly on almost the same spot as 2 weeks ago, we had an earthquake again, this time only a 3.5.
