It’s now become easier to forecast the next eruption of Alaska’s Bogoslof volcano. New research led by Pavel Izbekov, a volcanologist at the Alaska Volcano Observatory, is applying the foundations of diffusion chronometry—the study of chemical change in crystals over time—to a new eruption forecasting approach. Izbekov’s team used crystal clusters and their collective records […]

Amid the Arctic’s Hottest Year, Arctic Science Faces a Data Deficiency
The 20th annual Arctic Report Card reveals new highs in temperature and new lows in sea ice, as well as an uncertain outlook for the availability of federal data.
Credible or Counterfeit: How Paleomagnetism Can Help Archaeologists Find Frauds
Duplicating artifacts that preserve records from biblical times is a lucrative business. A method used for both dating artifacts and reconstructing Earth’s history could identify phony pieces.
Changing Winters Leave Indigenous Alaskans on Thin Ice
Researchers are blending Indigenous Knowledges with climate models to describe shifts in snow and ice.
Frictional Properties of the Nankai Accretionary Prism
A database of frictional properties from IODP drilling materials explores the range of slip spectrum and the generation of slow to fast earthquakes in the Nankai subduction zone in light of mineralogy.
Episodic Tales of Salt
When episodic pulses of road salt hit after a winter storm, the impact can be like a lightning strike for the environment.
Celebrating the MacGyver Spirit: Hacking, Tinkering, Scavenging, and Crowdsourcing
The MacGyver sessions allow scientist-tinkerers to have “nerd-on-nerd” discussions about do-it-yourself gadgets and gizmos.
The Long and the Weak of It—The Ediacaran Magnetic Field
A roughly 70-million-year interval of anomalously weak magnetic field during the Ediacaran period could have triggered atmospheric changes that supported the rise of macroscopic life.
When Does Rainfall Become Recharge?
Counting drips in caves is helping to reveal how much precipitation is needed to start refilling underground aquifers.
Changes in Slab Dip Cause Rapid Changes in Plate Motion
Periods of slab shallowing in the South American subduction zone appear to cause decelerations in Nazca plate motion.
