Whats going on at yellowstone?

Wow

700 pages


This has to be the biggest and most greatest resource about the Yellowstone caldera on the net







Hope that uplift chart was wrong

Time to get an updated avatar Puterman. Yours is 334 pages old!

If you are meaning the big mass of wobbly jelly on the one below that is the Mag 6.8 in the Banda Sea going through on a broadband or a long period instrument such as the LISS recorders. This is also the red line on the short period instruments.

LKWY.US.00.BHZ.2011.242

Interestingly it is not actually on all of them. Mm.




Here it is on an LH channel LKWY.US.00.LHZ.2011.242

I do believe that the second part of the wobbles is it coming round again! I can't see anything else that would do that unless it is the ........... no not big enough.

Nice to see you are still around. I have not seen you posting lately.

You had me going there - I thought we had got to page 1000 and I had not noticed!

Oh, you have changed it already. I'm still around, just got too busy to enjoy any ats leisure time for a while. Hope I haven't missed too much tectonic activity!

Here is her monthly report for August.

YELLOWSTONE VOLCANO OBSERVATORY MONTHLY UPDATE
Thursday, September 1, 2011 3:20 PM MDT (Thursday, September 1, 2011 21:20 UTC)

YELLOWSTONE VOLCANO (CAVW #1205-01-)
44°25'48" N 110°40'12" W, Summit Elevation 9203 ft (2805 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

During the month of August 2011, 25 earthquakes were located in the Yellowstone National Park region. The largest was a magnitude 2.0 event on August 10 at 10:46 AM MDT, located about 18 miles northeast of Fishing Bridge, WY. No swarms were recorded in August.

Earthquake activity continues at relatively low background levels.

Ground Deformation Summary: A strong seasonal signal, probably related to last winter's extraordinary (~200% of normal) snowfall, is apparent on many of the GPS records in and well outside Yellowstone. This signal complicates interpretation of the GPS data, but detailed analysis indicates that caldera subsidence, which began about 1.5 years ago, likely persists. YVO scientists are working to understand the nature of the unusual signal, and will continue to monitor it carefully.

Anyone want too guess,, whats going on in the Check/German border??
looking for anyone who might be familiar with patterns,,,

boy thats some pattern???

Okay, anyone know exactly what this means...

"Ground Deformation Summary: A strong seasonal signal, probably related to last winter's extraordinary (~200% of normal) snowfall, is apparent on many of the GPS records in and well outside Yellowstone.

I did a quick search and figure it's "crustal displacement due to water loading".
If I'm off base please correct me.

GPS global position,,

depth ??? i always assumed surface depth.

depends how far the GPS DATA SIGNAL
penetrates.
i always assumed. surface.

singal = location markers moved.

crustal?
mantle?
mountain ranges?
the hole at yellowstone?

not enough info on the DATA

earthquake.usgs.gov...
But she is soooo quiet,.
a few, but tiny,..
shhhhhhhhh

Hi Robin, yes ice on the GPS antenna gives false readings - a seasonal signal. This happens on Grimsvotn in Iceland as well. Probably in other but that is the only one I know about.

On Grims it makes it look as if there is inflation when there is not.

Not that quiet. There have been several quakes, but marked as Western Montana and not Yellowstone.

The lates I could find was at Hebgen Lake:
M 1.5, western Montana
Date: Monday, September 26, 2011 05:53:54 UTC
Sunday, September 25, 2011 11:53:54 PM at epicenter
Depth: 6.30 km (3.91 mi)

looks like 700 pages was enough for yellowstone.... the grant lady went into an deep sleep?? :-)

And without further ado from our sleepy Momma? the latest anticipated update :-)

I appears to me that I am not the only one perplexed by the Ground Uplift- Folks - Jake - I am sorry, while yes, the record snowfall/water levels of last year "could have" moved the instruments - - - by summers end, they would have dropped back to subsidence levels - This has NOT happened - try again :-)

Nor am I able to check on the temperature data recently. Such as Steamboat. volcanoes.usgs.gov...
I can find no data available at any of the monitoring stations. Curious

I will start checking more frequently.

Temps are partially back online . Nothing major to report. GrayLakes had an interesting bump up in temperature on the monthly graph. volcanoes.usgs.gov...

Forgive I havent followed this thread all the way here is a nice article relating to possible causes of super-volcano eruptions

Researcher Patricia Gregg explains the process: "You can compare it to cracks forming on the top of baking bread as it expands. As the magma chamber pressurizes at depth, cracks form at the surface to accommodate the doming and expansion. Eventually, the cracks grow in size and propagate downward toward the magma chamber. In the case of very large volcanoes, when the cracks penetrate deep enough, they can rupture the magma chamber wall and trigger roof collapse and eruption."

nice read check it out

I also found a brief article on Supervolcanic eruptions i thought i would share, although this thread is much more informative lol...

Read it here.

I have been searching for a map that shows the current position of the magma plume/chamber in relationship to the Yellowstone caldera. The crust is moving over the hot spot and I am curious how far 'off center' (can't think of the term I want) it is. At some point in the future the crust will move far enough and a new volcano/caldera will be created. Anyone ever hazard a guess when and where it will be?

Between the sensationalism and incorrect information on the net I haven't found this kind of information.

Thanks in advance for any useful information, and have a great day.

Thank you for the map. But I've seen it before and other forms of it. I am looking for a map or something that shows the actual position of the magma plume and chamber in relationship to the Yellowstone caldera. I cannot find the one saw a months ago (it may have been on TV) but it shows the plume is no longer under Yellowstone magma chamber but shifted to the northeast which follows the map you posted.

I can find images of what the plume and magma chamber look like but nothing that has a map of Yellowstone on top of it. To show how far the chamber has drifted away from the plume.
