USGS Cascades Volcano Observatory Geophysicist Rebecca Kramer works on the installation of the GPS mast at new station LSON, at Mount Hood. The GPS measures subtle ground deformation that can occur in response to magma entering or leaving the magma reservoir several miles below the summit.

Volcano Disaster Assistance Program Geophysicist Jeremy Pesicek digs a hole for a seismometer at station BRSP, on the north flank of Mount Hood. The seismometer, which detects earthquakes, is buried at a depth of at least 1 meter (3 feet).

USGS Cascades Volcano Observatory Geophysicist Emily Montgomery-Brown uses a drill to create a small hole in volcanic rock that will support a GPS mast. The effort was part of a three-station installation project at Mount Hood in 2020. This station location is called BRSP.

A USGS Cascades Volcano Observatory field team waits on this remote north flank of Mount Hood, as a helicopter delivers supplies and equipment to station BRSP. The station was installed with minimal impact on the environment. A helicopter delivered equipment via external sling load and USGS personnel accessed the site by foot.

Scientists use a MultiGAS instrument (gray, hard-shell case) to measure gas compositions from the East Lake hot spring in the Newberry caldera. The photo was taken on August 3, 2020 just after sunrise. The vapor above the hot spring and lake is typical for cool mornings and is not visible later in the day.

Earthquakes at Mount Rainier from 2010 to 2019. As shown in the graphic, fluids from the magmatic system beneath the volcano rise through existing cracks and weaknesses in the crust. Along with rainwater and ice/snow melt, these fluids combine to create a hydrothermal system within the volcano.

GeoGirls hike to Willow Creek, on Mount St. Helens’ Pumice Plain, to learn more about the ecology of the blast zone and how the area has recovered since the catastrophic May 18, 1980, eruption. Here, they look at stream characteristics and how it has influenced the return of life to the area.
