question..is there a regulair time line in it....
if so.... wat cuases it...the sun ..planets....watever...
Well if you look at the prior signals @ YPP, on the 29th, 27th you can see the signal start off small, then grow over time to a max intensity, after
which it starts to go lower again.
Then if you look at today's cluster there is a small spike a pause then a larger one. If you contrast that to the typical earth quake signal, there
are some similarities, enough so that I would say it's a micro-quake (under 1.0), with a small after quake. Then a few moments later a second micro
quake.
There has been a lot of rain in the past week or so, so it is not unlikely that a fault would get 'lubricated' from ground water and slip a little.
The University of Utah (UoU) has the responsibility for monitoring and evaluating the quakes with in the park, and a good portion of the Inter
Mountain West. In time you will see that UoU does not work on the weekends, and that the only time we get reports on the weekends from the USGS site
about quakes in Yellowstone, is if they are 3.0+ and are picked up by folks 'other' than the UoU. They will staff the monitors on the weekend if
there is a excessive amount of activity, like say at the beginning of the year. If you take today's reports of quakes from Utah, I just recently got
a email report stating there was a 1.0 in Utah... for 10:05 UTC... and it's several hours after that.
Personally I think it's kinda stupid to have to wait for UoU to have the time to decide what is a quake and what isn't. I also think that they are
missing a crap load of interesting things. SO I am looking for the 'cool and odd' signals, trying to see if there is something happening.
What I do when looking at the sensors is first I look at the right hand side for the UTC time of the signal. Then I open a pair of new tabs, one
showing the World Earth Quake list (3.0 & greater) then I open the US Earth Quake List (1.0) and greater. Then I look for events within 5 minutes of
the signal on the 1.0+ USA list , that I am trying to figure out the cause of. If there is a reported event 5 minutes prior to the one I am checking
the time of, it's related to that one.
Then looking at the World 3.0+ list it gets a bit trickier. Cali & Alaska events take 3-4 minutes to reach the park. Puerto Rico takes about 12-15
minutes, and so on. Basically if there is an quake listed within 20 minutes prior and it's within the South America Region you can discount that
event.
Further out, the events if they are 5.0+ show up as Love waves, (sawtooth) but it takes a serious quake to generate them.
Largely it falls to you to decide what is noteworthy and to learn what the signals may be. The ATS motto is to deny ignorance, so read up, learn and
ask questions.
