Decoding an Ancient Tsunami from the Ground Up
The seafloor around Santorini is helping scientists investigate forces behind the devastating Minoan tsunami.
Hig Higman: Trekking Across the Last Frontier on the Hunt for Geohazards
Higman specializes in human-powered research expeditions in Alaska’s epic landscape.
A 1952 Landslide Hints at Early Permafrost Thaw in the Arctic
Scientists took a deeper look at a 70-year-old slide and found that climate change likely set the stage for the disaster.
Social Media Posts Reveal Human Responses to Deadly Tongan Eruption
Quantifying human responses to natural disasters could improve preparation for future threats, scientists say.
Making Underwater Cables SMART with Sensors
Future cables that stretch across the ocean, transmitting cat videos and financial transactions, could also contain temperature, pressure, and seismic sensors that would allow scientists to spy on the seafloor.
Looking to the Sky for Better Tsunami Warnings
Pairing navigation satellites and CubeSats could provide earlier, more accurate warnings of approaching tsunamis and other impacts of extreme events.
Under Pressure: Recording Earthquakes at and Below the Seafloor
Cabled ocean-floor observatories record ground shaking and pressure variations, which contribute to early warning systems and give us a unique view of the ocean–crust coupling.
A Really Big (Global) Splash at Chicxulub
What caused a tsunami 30,000 times more powerful than the December 26, 2004 Indian Ocean tsunami? A new modeling study says this was one of the results from the Cretaceous Chicxulub asteroid impact.
Seismic Sources in the Aleutian Cradle of Tsunamis
Research over the past decade in Alaska’s Aleutian Islands has offered surprising insights into the pulses of great earthquakes that generate dangerous, often long-distance tsunamis.
