Stone Caldera - the Volcano to watch
The Yellowstone Volcano Observatory (YVO)
is in the Yellowstone National Park. 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.
"YVO has adopted the new U.S. Geological
Survey (USGS) standard volcanic alert-level system. The site
provides real time Status Reports, and Information Releases will
now include both an alert level and an aviation color code for
characterizing the level of unrest and eruptive activity (see
the new Status Page.
Yellowstone is currently at the alert level, NORMAL (Typical
background activity of a volcano in a non-eruptive state),
and Aviation Color Code GREEN (Volcano is in normal, non-eruptive

the Public of Volcanic Activity at U.S. Volcanoes".
March 2006, a study was concluded about a
period of uplift in the northern part of the Yellowstone caldera.
The recent findings, used Satellite Technologies to Detect Uplift
in the Yellowstone Caldera.
Of course, the Yellowstone caldera is a volcano,
and it almost certainly will erupt again someday. It’s possible,
though unlikely in the near future. Yes, future eruptions could
reach the magnitude of Yellowstone’s three largest explosive
eruptions, 2.1 million, 1.3 million and 640,000 years ago.
Smaller eruptions, however, are far more likely, and no eruption
seems imminent on the timescale that most people truly care about
— their lifetime or perhaps even the next few hundred or thousands
of years. So while everyone gets excited about hollywood movies of
this genre, we all should still keep a scientific eye on Yellowstone!
