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.
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.
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.
