Information revealed by 2018 Kīlauea eruptions leads to new caldera models
Starting in May of 2018, the Puna District of Hawai’i began to experience back to back eruptions of their Kīlauea volcano, along with earthquakes. A new paper lays out a helpful timeline of the initial eruption and following events, as well as addressing the applications for the future from the collected data.
GPS monitoring of draining glacial lakes shows how one lake can affect another
A new study utilizing GPS station measurements on the Greenland Ice Sheet helps scientists understand how lakes atop the ice sheet seem to synchronously drain, providing insight into ice sheet stability.
What’s tearing the western U.S. apart?
Different forces are tearing the western U.S. apart. Which ones are most important?
Cracking ice: seismic signals identify most rapid rupture recorded on Antarctic ice shelf
In Western Antarctica, the Pine Island Glacier ice shelf cracks and calves. One of these rifting events was observed via seismic sensors, demonstrating that while the tear was slower than expected, it’s still the fastest through-cutting fracture in a floating ice shelf ever recorded.
GPS stations are now part of the ShakeAlert® Earthquake Early Warning System network
GPS stations augment seismometers, significantly improving the system’s ability to accurately detect the largest earthquakes.
Greenland GPS network measures the ice sheet’s weight loss
In a recent study, researchers treat the entire GNET network as a single instrument weighing the loss of Greenland’s ice.
GPS data capturing eclipse phenomena in ionosphere
The passing shadow of the eclipse creates a natural experiment, suddenly reducing solar energy to an isolated area of the ionosphere.
Sensing potentially tsunamigenic Alaskan landslides resulting from retreating glaciers
As the world warms, glaciers retreat, leaving behind over-steepened slopes that are prone to landslides. In places like coastal Alaska, landslides that slip into the ocean can spell disaster.
Sea level rise, Earth’s variable rotation, and a new leap second problem
A new study tries to disentangle the factors affecting Earth’s rotation—and finds that we may have a technical problem our on our hands in the next few years.
Infrasound in Idaho’s mountains come from waterfalls, thunderstorms, and earthquakes
Scientists demonstrate how an array of many infrasound sensors can hear waterfalls, thunderstorms, and earthquakes (yes, the latter makes noise, too).
