[Geysers] Seismographs

[Karen Low]

1) The University of Utah seismograph site doesn't show any thing for the right day or location.  They may filter out seismic events extremely close to the surface, which is usually done to exclude artificial quakes such as blasts associated with mining.

2) Maybe the Giant platform shaking was caused by exicted gazers jumping around?  (joke)

Several questions:

1) When Giantess registers on the seismograph, how big of an eartuquake
does it create? M 2.0? 1.0?

2) Years ago I remember hearing that prior to Giant Geyser's eruptions,
the platform would shake and pound. Yet I have not heard anybody mention
this for perhaps the last 15 years. Did this really happen? And if so,
does it still happen?

3) Does anyone have the URL for the Yellowstone photo files? It appeared
on the list last winter, but I have since lost it.

Assuming I did not miss finding it on the GOSA website, it would be a nice
additional link.
