Examining Alaska’s Earthquakes on Land and Sea
The Alaska Amphibious Community Seismic Experiment is taking a close look at seismic activity along the Alaska Peninsula to understand earthquakes in this little-studied region.
Unused Fiber-Optic Cables Repurposed as Seismic Sensors
So-called dark fiber can serve as regional seismic activity monitors and also detect earthquakes thousands of kilometers away, according to new research.
Oceanic “Pump” Sends Small Carbon Particles to Twilight Zone
Underwater gliders provide unprecedented, daily data that reveal new insights into how carbon gets from the atmosphere to the deep ocean.
A Digital Mayfly Swarm Is Emerging
Low-cost, open-source data collectors and a suite of collaborative online tools are making big leaps in the field of watershed monitoring.
Can Moderate Space Weather Have Major Impacts?
Pipeline corrosion is an example of why we need better awareness of how long-term exposure to moderate space weather may have significant economic impact by slowly degrading vulnerable systems.
Collaboration Reveals What’s Beneath the Surface
How do scientists look underground? Answering questions about Earth’s interior requires an attack from many angles.
Harnessing the GPS Data Explosion for Interdisciplinary Science
More GPS stations, faster data delivery, and better data processing provide an abundance of information for all kinds of Earth scientists.
Bulging, Shrinking, and Deformation of Land by Hydrologic Loading
The deformation of continents by groundwater can be measured locally by GPS or detected from satellites, but more precisely monitored when measurements are combined with a hydrologic model.
Huge Spike in Quakes Badly Damages Kīlauea Observatory
Meanwhile, some scientists say that the 35-year eruption from the Pu‘u Ō‘ō vent has ended and that the flows since 3 May are a new eruption. Others take issue with this view.
