Though Chile is known for several major earthquakes, the Atacama seismic gap features slow movement that scientists seek to unravel.

Changes in trace amounts of the element thorium in two Colorado catchments appear to be explained by subsurface fracturing. The cause of fracturing might be attributable to distant earthquakes.

EarthScope Consortium would like to congratulate a number of community members—including former staff members, collaborative projects, and individuals who have volunteered considerable time as Board of Directors members or short course instructors—on receiving 2023 AGU awards.

This summer, EarthScope hosted seven students as part of the International Undergraduate Internship for Seismology and Geodesy Skills Building. Interns from six different countries spent the summer working virtually on a seismology or geodesy research project.

EarthScope Consortium will be one of 16 institutions participating in the new NSF-funded Cascadia Region Earthquake Science Center (CRESCENT), which will study the Cascadia subduction zone and improve earthquake resiliency and preparedness across the Pacific Northwest.

Seismic monitoring of Yellowstone’s Steamboat Geyser showed that signals appeared weaker in winter—because of snow cover.

During the summer of 2021, the magnitude 8.2 Chignik earthquake ruptured on the Alaskan coast, providing scientists, such as a team led by Parameswaran of University of Alaska Fairbanks, with a test case for a future early warning system for the region.

Bailey Fitzgerald is a fourth year PhD student at Ohio State University studying the relationship between earthquakes and underwater landslides. This summer Bailey has been selected to participate in the Student Career Internship program as a science communication intern.

The Cascadia Subduction Zone is not your typical subduction zone. It is characterized by unique “slow slip events” that occur in the intervals between megathrust earthquakes along the fault.
