A three-dimensional hydrodynamic model of the lower Columbia River (LCR) was constructed using the Delft3D Flexible Mesh (DFM) modeling suite to simulate water levels, flow, and seabed stresses between January 1, 2017, and April 20, 2020

Looking southwest from the Steens Mountain summit area into the Alvord desert of eastern Oregon.  This fault-block escarpment reveals the oldest lava flows of the Columbia River Flood Basalts, which erupted about 17 million years ago.  Three or four vertical dikes that feed these flows are evident in the midground ridge where they stand as rock walls cutti

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.

Combined seismic/GPS station LSON, on Mount Hood, installed at the end of September 2020. LSON is one of three new stations that enhance the existing monitoring network at this high-threat volcano.

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.

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.

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).

The USGS Cascades Volcano Observatory installed an 8-station seismic monitoring network at Newberry volcano in 2011, which includes station KWBU.
