Earthquakes make waves in the ionosphere—another signal to study
In order to extract as much information as possible from ionospheric signals, we need to understand the patterns in great detail. A recent paper used the 2016 magnitude 7.8 Kaikoura earthquake to see what we could learn from testing the data against simulations.
Strainmeters and GNSS stations reveal subtle fault movements after the 2019 Ridgecrest earthquake
When we experience a significant earthquake—along with any foreshocks or aftershocks associated with it—the shaking is hard to ignore. But there are also subtle movements afterward we may only notice with the help of precision instruments.
Sea level rise projections depend on improved bedrock models
A new study uses the latest maps of the structure beneath Antarctica to see how important realistic crust and mantle information is to sea level rise. The answer? It’s pretty important.
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.
NSF SAGE/GAGE Community Science Workshop highlights the breadth of the geophysical toolkit
The techniques in our geophysical toolkit have grown exponentially over the years. By understanding research in these fields using these tools, we can see the applications to geophysics and bettering society.
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.
GPS monitoring of draining glacial lakes shows how one lake can affect another
A new study utilizing GPS station measurements on the Greenland Ice Sheet helps scientists understand how lakes atop the ice sheet seem to synchronously drain, providing insight into ice sheet stability.
What’s tearing the western U.S. apart?
Different forces are tearing the western U.S. apart. Which ones are most important?
GPS stations are now part of the ShakeAlert® Earthquake Early Warning System network
GPS stations augment seismometers, significantly improving the system’s ability to accurately detect the largest earthquakes.
Greenland GPS network measures the ice sheet’s weight loss
In a recent study, researchers treat the entire GNET network as a single instrument weighing the loss of Greenland’s ice.
