Washington’s Volcanoes Are Experiencing Seismic Tremors from an Unlikely Source: Glaciers
At three Cascade Range volcanos, glacier movement is causing tremors that visitors and even people in nearby cities have been able to feel.

California Quake Faults Are Highly Sensitive to Solid Earth Tides, Say Scientists
Oceans have tides, and so does the solid earth. Could they have an effect on earthquake faults? Yes, say scientists, but that doesn’t necessarily mean they cause big quakes.

Gauging Losses and Lessons in Turkey’s Unfolding Earthquake Tragedy
As earthquake engineers stress, most of the time, buildings kill people, not the shaking itself. It’s exceedingly hard to unbuild, move back, or retrofit buildings at scale.

Balancing Act: Can Precariously Perched Boulders Signal New York’s Earthquake Risk?
Long ago, melting glaciers dropped giant boulders onto surfaces in the New York City exurbs, and many seem to remain in their original, delicately balanced positions. Can they be used to judge the maximum sizes of past earthquakes?

Looking for the Origin of Slow Earthquakes in the Guerrero Gap
We are underway on our 48-day long expedition offshore of the west coast of Mexico near Acapulco, where the young Cocos oceanic plate dives beneath the North American plate.

Sylhet City, Geology, and Packing Up
We finished our electromagnetic survey and mini-field school in northern Sylhet, Bangladesh, with lectures and field trips to see the geology by car and boat.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
