Whats going on at yellowstone?

The repeaters at 1600 to 1700, are interesting...

the repeaters around 1600 on this webicorder are unique..

OK, I am confused.

YMR does not have an SHZ channel so where is this data coming from?

www.iris.edu...

Apologies it does, but it has no realtime data according to Bud Explorer and as no information past 2005



This is all I can get in Vase

Those channels available from YMR have quite good sound. They
are from a broadband siesmometer and even though you can't
see much happening, you can hear quite a bit.

The short period seismometer apparently is too noisy for them to
archive the data.

whats that? oO

Yes I think I realised that, but what I was getting was that the plot in the interveners from the post above is of SHZ, and I can't get that one.

QuakeData 3.5.3 Build 42 Available

You can get the download using the link in my signature. It is about 13Mb download.

If you have already installed QD then you will possibly see an update when you re-start after installing (if this has not happened already). Same goes for a fresh install. This is needed to update the database for the plot stations.

If you are installing from new I recommend that you also download the data file which has been updated to yesterday and contains all the station information.

If you are downloading and installing the latest data file you MUST download and install the registry entries file and unzip it to disk, then double click to install the entries. You should do this |BEFORE you run the program again.

You can also run this if it has already been updated and it will install all the web cam settings and lat/lon shapes and plot settings that I use.

There is still work to be done on the plot viewers, but basically they are all working.

Since we can't get this data any other way, it is hard to tell what
it might be. It looks possible that the gain might have been turned
up and it is showing a much louder version of the noise that has
been showing on that station for a long time. I have been going
to ask about it, but I figure it must have been discussed in this
thread previously somewhere.

There is some quake activity this morning on B207
www.iris.edu...

It also shows up on YMR, YFT, YMC and others faintly. So I would
guess they are real quakes.

I have just discovered that LKWY has acquired a location code of 00 which it did not have before. This is why I was not getting plots.

LKWY.US.00.BHZ.2010.091

LKWY.US.00.LHZ.2010.091

It does NOT however have an SHZ channel anywhere so WHERE is this data coming from?

Here are the channels available in VASE

I note is says 500 mV so it is quite sensitive if this SHZ channel is to be believed.

You are right and you beat me to it.!!!
The BHZ channel is sampled at 40 Hz, so with your quakedata,
using 2000Hz I got a nice 800 Hz tone. For the sample right
after 00:00 hours UTC where the amplitude was still low. There
are so many breaks in the data, I have not heard the high amplitude sample yet. The other data available from LHZ is
sampled at 1 Hz so the signal does not show in those channels.

I heard a similar tone on the broad band data from YMR, and it
also repeats on a regular basis, then in addition there is a higher
frequency tone that also repeats but less frequently.

Edit: I just listened to the louder bursts and they are the same
frequency, just louder. Definitely man made signals.

This morning tide? was again higher on B944 and the micro
quakes were showing up on B208, B944 and especially on YHB.
www.isthisthingon.org...

I downloaded the SAC files from 07:00 to 12:00 UTC for YHB and
YDC and converted them to audio. And surprisingly much of the
activity is clearly being picked up by both seismometers. I am
still trying to find out if these quakes are real earthquakes or
if they might be caused by tidal pull on the ice which is on lake
Hebgen. The sound that is made is not as bright (does not contain
as much high frequency energy) as known earthquakes. If it is
being caused by ice cracks I can understand that the water or an
air pocket between the ice and the water might filter out the high
frequencies.

I did some searching through the data archived at the above URL
for 2008 and 2009 and have not found these micro quakes
during summer months. All this micro activity is taking place
around Lake Hebgen and Yellowstone Lake, and I have not found
it at other instruments. So if these are real quakes it might
demonstrate that water from the lakes is having some kind of
effect down below. But if it is ice it would be a whole different
story.

If anyone has any data on this, or lilnks to papers I would
appreciate knowing about it.

Thanks

I would imagine that cracking ice would have an effect on the seismos. I await your results with interest.

These all certainly 'look' like micro quakes, but perhaps they are not.

Edit: Had to go back and have a look at your post. If this is only around the lakes, and only in the winter months, then I guess you may have sussed that one. As I say I wait the results of your deliberations.

Well, there are definately three nice sized micro quakes. Stongest on YMR, but shows up on all surrounding stations.

if the dept is correct then i def dont like it ....

also the monthly update from YVO.


YELLOWSTONE VOLCANO OBSERVATORY MONTHLY UPDATE
Thursday, April 1, 2010 3:29 PM MDT (Thursday, April 1, 2010 21:29 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 March 2010, 66 earthquakes were located in the Yellowstone region. The largest event was a magnitude 2.7 on March 29th at 7:35 PM MDT, located about 8 miles northeast of Canyon Junction, YNP. No earthquake swarms were recorded during March and seismicity continues at background levels.

Ground Deformation Summary: Continuous GPS data show that uplift of the Yellowstone Caldera has slowed significantly. Uplift rates for YVO GPS stations are less than 2.5 cm per year. The WLWY station, located in the northeastern part of the caldera, underwent a total of ~23 cm of uplift between mid-2004 and mid-2009. Its record can be found at:
pboweb.unavco.org...

The general uplift and subsidence of the Yellowstone caldera is of scientific importance and will continue to be monitored closely by YVO staff.

An article on the recent uplift episode at Yellowstone and discussion of long-term ground deformation at Yellowstone and elsewhere can be found at: volcanoes.usgs.gov...

The Yellowstone Volcano Observatory (YVO) is a partnership of the U.S. Geological Survey (USGS), Yellowstone National Park, and University of Utah to strengthen the long-term monitoring of volcanic and earthquake unrest in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.

It hasn't been reviewed, the depth was automatic.

Yea, there is a red square in Yellowstone!!
earthquake.usgs.gov...

Its a 2.5 preliminary.
earthquake.usgs.gov...

There were a couple of others earlier which showed pretty good
around the park.

Edit:
It has been reviewed and downgraded to 2.4

Well, it's caused me to bring GEE back up.

Warrants some attention, I think. Given the location and so-far depth. Will be interesting to see if this develops into anything over the coming days!!

reply to post by EngTech36


That seems to be only very slightly north of the previous swarm.

Right on the caldera line



[edit on 3/4/2010 by PuterMan]

reply to post by PuterMan



yeah but guys its less then a mile down is what has me concerned !!!!!!!!!!

I agree....the combined fact that it's right on the line of the caldera AND less than a mile below the surface is, I think, significant.

Luckily, so far there hasn't been anything further.
