Gas sampling at Mount Shasta builds a long-term record of volcanic emissions
One of the three main ways that California Volcano Observatory scientists monitor the state’s threatening volcanoes is by sampling the gases that are released from magma deep below (in addition to monitoring seismicity and deformation).
A time when Old Faithful wasn’t so faithful
Old Faithful Geyser got its unique name in the 19th century because its eruptions were so regular and predictable. But during parts of the 13th and 14th centuries, the geyser did not erupt at all.
Exploring thermal areas in Yellowstone's remote southwest corner
There are over 10,000 thermal features scattered throughout Yellowstone National Park, and many are in remote locations. Attempting to make a more complete record of water and gas chemisty of all the park's features, scientists from the USGS and the National Park Service travelled to the southwest corner of the park to study remote thermal areas around Boundary Creek and the Bechler River.
Development of a field-portable helium isotope detector for continuous, real-time monitoring of active volcanoes
Scientists from the USGS Volcano Hazards Program have been developing various technologies that allow for real-time and continuous measurements of gas concentrations in active volcanoes.
