Organizational announcements and stories about our work and the science we support.
Scientists demonstrate how an array of many infrasound sensors can hear waterfalls, thunderstorms, and earthquakes (yes, the latter makes noise, too).
In order to monitor compliance with the Nuclear-Test-Ban Treaty, the CTBTO is developing ways to verify nuclear explosions. A new benchmark dataset based on (non-nuclear) experiments is one example.
Wind-driven ocean waves beat on Earth’s seafloor, creating a continuous signal for which seismic stations around the world listen—a signal that is increasing.
The Columbia River has sawed its way to the sea as a mountain range grew up around it. There is history to be read in the walls of the gorge, including history of the mountains’ rise.
Students gain an authentic scientific experience by exploring large, real-world datasets and building coding skills with GeoCode's educational modules.
To facilitate calibration of InSAR ground displacement measurements, NASA JPL corner reflectors have been deployed next to NOTA stations along the San Andreas Fault. Check out this video to learn more!
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.
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.
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.
Believe it or not, the length of each day is not always exactly 24 hours. Though the changes may be virtually undetectable to the regular person, scientists are uniquely aware of the lengthening and shortening of days over time.
