When seismic sensors aren’t detecting earthquakes, they’re picking up other vibrations—even shakes too subtle for people to feel. This ambient seismic noise might be able to tell scientists what’s happening at Mount St. Helens during times of activity and purported respite.

A new paper using InSight data presents a noteworthy conclusion—seismic velocity data is best explained by the presence of liquid water.

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.

InSight has advanced our understanding of the Martian interior by using seismic techniques typically applied on Earth. One instrument, the Seismic Experiment for Interior Structure (SEIS) returned data that shows marsquakes from recent impacts of space debris on the surface. Compared to the orbitally-imaged catalog of craters, the seismically-detected events don’t seem to entirely match. 

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.

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. 

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.

A new machine learning methodology utilizes seismic data to see if a volcanic eruption can be forecasted.

Different forces are tearing the western U.S. apart. Which ones are most important?
