GPS data capturing eclipse phenomena in ionosphere
The passing shadow of the eclipse creates a natural experiment, suddenly reducing solar energy to an isolated area of the ionosphere.
Sensing potentially tsunamigenic Alaskan landslides resulting from retreating glaciers
As the world warms, glaciers retreat, leaving behind over-steepened slopes that are prone to landslides. In places like coastal Alaska, landslides that slip into the ocean can spell disaster.
Sea level rise, Earth’s variable rotation, and a new leap second problem
A new study tries to disentangle the factors affecting Earth’s rotation—and finds that we may have a technical problem our on our hands in the next few years.
Infrasound in Idaho’s mountains come from waterfalls, thunderstorms, and earthquakes
Scientists demonstrate how an array of many infrasound sensors can hear waterfalls, thunderstorms, and earthquakes (yes, the latter makes noise, too).
Nuclear explosion monitoring gets a new dataset
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.
Seismometers listen in on ocean waves in a warming world
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.
Magma and mountain building at the Columbia River Gorge
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.
NSF-funded GeoCode project demonstrates educational impact of coding and using large, real-world datasets
Students gain an authentic scientific experience by exploring large, real-world datasets and building coding skills with GeoCode’s educational modules.
Corner reflectors installed at NOTA stations for NASA JPL Project
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!
Fast and Slow: Chile’s subduction zone moves in distinct ways
Though Chile is known for several major earthquakes, the Atacama seismic gap features slow movement that scientists seek to unravel.
