Leveraging Next-Generation Tsunami Early Warning Systems to Save Lives
Tsunami early warning systems save lives not just when they are fast or accurate, but when they are trusted, understood and acted upon.

Cascadia Subduction Zone, One of Earth’s Top Hazards, Comes Into Sharper Focus
Where tectonic plates collide off the coasts of the western United States and Canada, giant earthquakes and tsunamis occur. The last one was 324 years ago. When will be the next?

Observations While on Quarantine in Newport, Oregon
Before embarking on a 6-week voyage to scan for Cascadia’s megathrust fault, the research team had to quarantine for two weeks in a hotel.

Using Sound to Study Underwater Volcanoes
To find out how volcanoes in the Pacific Ocean influence earthquakes and tsunamis, a team of scientists listens for ‘echoes’ from under the sea.

Alaskan Coast at Risk of Catastrophic Landslide and Mega-Tsunami
Geoscientists estimate that a mountain slope could collapse into Prince William Sound within a year, and likely within 20 years, triggering devastating waves.

Shifts in Deep Geologic Structure May Have Magnified Great 2011 Japan Tsunami
A new study looks at why the 2011 Tohoku tsunami off Japan was unexpectedly huge.

Ocean Sediments Off Pacific Coast May Feed Tsunami Danger
Tightly packed sediments help the Cascadia Subduction Zone generate large earthquakes, and could boost its ability to trigger a large tsunami.
-
New Images From Under Alaska Seafloor Suggest High Tsunami Danger
Scientists probing under the seafloor off Alaska have mapped a geologic structure that they say signals potential for a major tsunami in an area that normally would be considered benign.

Lamont to Develop New Earthquake and Tsunami Warning System
A new pilot program led by the Lamont-Doherty Earth Observatory aims to provide earlier and more accurate warnings of damaging ground-shaking from earthquakes and the imminent arrival of tsunamis.
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
