A Brief FAQ About Recent News Reports
February 28, 2014
Recent weeks have seen a flurry of news, real and imagined, about the Yellowstone
volcanic system. We present here a brief FAQ about several topics that have
appeared in recent news reports.
Has earthquake activity at Yellowstone increased dramatically over the last
No. Earthquake activity is normal. When earthquakes occur, they appear on the
University of Utah's
Yellowstone Earthquake Map
, or on the
YVO monitoring page
. Also see our February 5, 2014

Is the recent episode of ground deformation worrisome?
No. Current rates of ground deformation are well within historical norms. Please
see our February 18, 2014
, for more information about ground deformation
Do helium emissions at Yellowstone signal an impending eruption?
No. YVO Scientist-in-Charge Jacob Lowenstern and colleagues recently published
research on helium (He) emissions at Yellowstone in the journal Nature. The
looked at apparent changes in the helium output of the
Yellowstone area during its two-million-year volcanic history, compared with
the previous two billion years of comparative stability. The research has
nothing to do with current activity at Yellowstone, and has no implications
about volcanic hazards. For a humorous and informative take on the new research,
