Ghosts and swarms put spotlight on seismicity in South Carolina
Could a set of local railroad ghost stories be related to small, understudied earthquakes?
Monitoring microearthquakes of energy-storing salt domes in the Southeast US
Seismic imaging can map out hidden weaknesses around salt caverns used to store oil and gas.
As above, so below: how geophysics can help us unlock secrets of the cosmos
Geophysical instruments make key contributions to some large astrophysics experiments.
Measuring California groundwater after a wet 2023―with seismometers
In early 2023, an incredible amount of precipitation fell on drought-stricken California. The surface effects were quite visible but it’s not quite so easy to track how this affected groundwater.
Seismologists use earthquake doublets to see how inner core flips its motion
A set of studies explores questions pertaining to the rotation of the inner core relative to Earth’s mantle.
A series of unfortunate events: climate change causes remote landslide, tsunami, and seiche
In East Greenland, a mysterious tsunami hit a military base on a remote island tucked into the fjords. At the same time, seismologists noticed a weird signal on seismic stations located around the world.
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.
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.
