Scientists explore past eruptions—and periods of quiet—at Mount St. Helens
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.
InSight data may have revealed water deep below the surface of Mars
A new paper using InSight data presents a noteworthy conclusion—seismic velocity data is best explained by the presence of liquid water.
The Rainier volcanic hazards detection system has been growing
Over the past few years, the Rainier Lahar Detection System has been upgraded with 25 new stations to better detect volcanic hazards on the mountain.
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.
Mars’ Crater Impact Rate Gets an Update with the Help of Seismic Data
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.
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.
If you feel it, chase it: using seismic signals to detect tornadoes
The threat of destruction and injury the tornado chasers show viewers in the 2024 movie “Twisters” is real, so what can be done currently to warn against tornadoes, and how do we detect and track them using geophysics?
Natural hazards put some species at increased risk of extinction
Natural hazards can leave many species in unprecedented conditions in an extremely short amount of time. A new study looks at natural hazards occurring where at-risk species live in order to help guide conservation efforts for ensuring their survival.
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.
Caves of the Moon: How radar sensing is finding new locations for future astronaut bases
Ambitions to return to the Moon are accompanied with plans to build a lunar base. Finding a suitable location for long-term habitation, however, requires careful exploration of the lunar surface. A newly discovered lunar cave could be the answer.
