24 April 2025—Could the seismic signal of an underground nuclear test explosion be “hidden” by the signal generated by a natural earthquake? It’s possible, according to a new review article published in the Bulletin of the Seismological Society of America that contradicts the conventional wisdom about explosion “masking.” The new… Continue Reading Could Seismic Signals from Earthquakes Mask the Signals of an Underground Explosion?
17 April 2025—Researchers from Los Alamos National Laboratory have been collecting seismic data from a submarine telecommunications fiber optic cable in coastal Alaska, exploring how the cable could be used to detect signals from earthquakes, ocean currents and marine mammals. Then the researchers learned about construction on an oil spill… Continue Reading Submarine Telecommunications Cable Detects Road Construction Explosions
17 April 2025—At the Seismological Society of America’s Annual Meeting, researchers posed a seemingly simple question: how wide are faults? Using data compiled from single earthquakes across the world, Christie Rowe of the Nevada Seismological Laboratory at the University of Nevada, Reno and Alex Hatem of the U.S. Geological Survey… Continue Reading How Wide Are Faults?
17 April 2025— Sediment cores drawn from four lakes in Guatemala record the distinct direction that ground shaking traveled during a 1976 magnitude 7.5 earthquake that devastated the country, according to researchers at the Seismological Society of America’s Annual Meeting. The earthquake, which killed more than 23,000 people and left… Continue Reading Lake Deposits Reveal Directional Shaking During Devastating 1976 Guatemala Earthquake
17 April 2025—In 1638, an earthquake in what is now New Hampshire had Plymouth, Massachusetts colonists stumbling from the strong shaking and water sloshing out of the pots used by Native Americans to cook a midday meal along the St. Lawrence River, according to contemporaneous reports. When Roger Williams, founder… Continue Reading Native American Names Extend the Earthquake History of Northeastern North America
17 April 2025—You’ve probably seen the posts while scrolling on your phone: a shaky TikTok showing shelves emptying and lights swaying inside a convenience store, or a WHAT WAS THAT?? tweet that captures an earthquake in progress. Researchers now show that Google’s large language model (LLM) Gemini can comb through… Continue Reading Study Applies AI to Social Media Posts to Estimate Earthquake Ground Shaking Intensity
