Spacecraft Surveys Shed New Light on Auroral Kilometric Radiation
Observations show low-density space channels guide Auroral Kilometric Radiation, like wind through mountain tunnels, offering new insights into its occurrence and directionality.
How Researchers Have Studied the Where, When, and Eye of Hurricanes Since Katrina
Twenty years after one of the country’s deadliest storms, scientists reflect on improvements in the ability to understand and predict disasters.
Glacier Monitoring from Space Is Crucial, and at Risk
A new community effort shows that Earth has lost 5% of its global glacier mass since 2000. The work highlights the necessity of spaceborne glacier observations and upcoming gaps in long-term monitoring.
Mapping the Whereabouts of Continents
A new method integrates Interferometric Synthetic Aperture Radar (InSAR) with conventional ground geodetic networks, taking us closer to high-resolution mapping of plate motions.
Orbiter Pair Expands View of Martian Ionosphere
Radio signals sent between two Mars orbiters—rather than between an orbiter and an Earth-based receiver—capture new insights into atmospheric dynamics.
Nudging Earth’s Ionosphere Helps Us Learn More About It
New observations and simulations capture the physics at play across each of the three main ionospheric regions.
Seismic analysis to understand the 13 February 2024 Çöpler Gold Mine Landslide, Erzincan, Türkiye
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. On 13 February 2024, the enormous Çöpler Gold Mine Landslide occurred in Erzincan, Türkiye (Turkey), killing nine miners. This was the first of two massive and immensely damaging heap leach mine failures […]
33.8 Million People in the United States Live on Sinking Land
The most populated cities in the country are slowly subsiding, posing risks to infrastructure and exacerbating flooding—and not just on the coasts.
“Transformational” Satellite Will Monitor Earth’s Surface Changes
The mission, jointly operated by the United States and India, will measure minute changes to land, ice, and ecosystems around the globe.
