Ghosts and swarms put spotlight on seismicity in South Carolina
Could a set of local railroad ghost stories be related to small, understudied earthquakes?
Using geodetic tools to monitor a changing Arctic
Two projects show how remote sensing and geodetic tools can help us study changing ecosystems and landscapes.
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.
Antarctica’s Mt. Erebus gets a seismic network upgrade
This field season, EarthScope staff spent time on Mt. Erebus for some major upgrades to the seismic network, including a new station. Final tally on batteries hauled around by helicopter? About 14,000 pounds.
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.
Laser scans aid in preserving Antarctic history
One recent Antarctic project supports the New Zealand Antarctic Heritage Trust’s work at Discovery Hut, a remnant of Robert Falcon Scott’s famous expedition.
Ear to the seafloor: using DAS to help harness offshore wind energy
California is looking to build offshore wind electricity generation―distributed acoustic sensing on existing cables could help site these projects.
Tracking magma movement during Mauna Loa’s 2022 eruption: an eye to forecasting
Distinguishing between intermittent unrest and an eruption’s prologue poses a major challenge to volcanologists responsible for forecasting earthquake activity. A recent eruption of Mauna Loa, Hawai’i provided scientists a unique opportunity to tackle this problem.
Yellowstone’s magma system comes into focus
A new study uses a dense array of magnetotelluric measurements to generate a high-resolution image of Yellowstone’s magmatic guts.
