Mount Hood, Oregon, earthquakes from a swarm that occurred December 8-13, 2023 as compared to previous earthquakes. The recent earthquakes are shown with red circles. Earthquakes that have occurred since 2010 are shown as unfilled gray circles. All circles are sized by their magnitude. Top: Map view of seismicity at Mount Hood.

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.

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.
