A couple of weeks ago, we posted what seemed to be reliable information on the earthquakes swarms happening in the West Yellowstone caldera area. The new information that we have now received proves some of the earlier information to be faulty. Let me explain. According to the USGS volcano observatory, Volcano Hazards program at Yellowstone, the earthquake activity is normal. When earthquakes occur, they appear on the University of Utahs Yellowstone Earthquake Map, on the YVO monitoring page. Also see our February 5, 2014 Information Statement about the misinterpretation of noise from a broken seismometer. 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 Information Statement, for more information about ground deformation at Yellowstone 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 new research 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.
