New method to auto-detect earthquakes tested at Mammoth Mountain
Researchers in a new paper utilized a seismic array around Mammoth Mountain to test out a new automated detection workflow to see if they could reliably identify the precursors to volcanic activity.
How Listening to Rocks Unveiled the Structure of an Aquifer
When features below Earth’s surface aren’t easily visible, geophysicists turn to their multi-disciplinary toolbox for answers. In a new study, geophysicists took a listen to ambient noise with seismometers to map out the complex structure of a Florida aquifer.
How geophysics can help us be better prepared for climate change
Using geophysical instrumentation and techniques can allow researchers to understand how natural resources may be affected by changing climate, and how we can manage these changes properly.
Pairing machine learning with GNSS and InSAR could help forecast eruptions
A new machine learning methodology utilizes seismic data to see if a volcanic eruption can be forecasted.
What’s tearing the western U.S. apart?
Different forces are tearing the western U.S. apart. Which ones are most important?
Cracking ice: seismic signals identify most rapid rupture recorded on Antarctic ice shelf
In Western Antarctica, the Pine Island Glacier ice shelf cracks and calves. One of these rifting events was observed via seismic sensors, demonstrating that while the tear was slower than expected, it’s still the fastest through-cutting fracture in a floating ice shelf ever recorded.
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.
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.
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.
Thorium spikes in Colorado streams could be caused by bedrock fractures
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.
