Fiber-Optic Networks Can Be Used as Seismic Arrays
A new study repurposes telecommunications cables to harness sound from light. The method can accurately measure ground motion from distant earthquakes.
Drilling into a Future Earthquake
Researchers drill into a fault that is anticipated to rupture in coming decades to study fault structure and earthquake physics.
More Earthquakes May Be the Result of Fracking Than We Thought
Scientists show small earthquakes caused by fracking near Guy-Greenbrier, Ark., in 2010 that could have been early indicators of high stress levels on larger faults deeper underground.
Damage Assessment by Laser Could Focus Postearthquake Response
Airborne lidar surveys taken before and after a powerful 2016 earthquake in Japan revealed the potential for such surveys to identify hard-hit buildings quickly.
Were Mexico’s September Quakes Chance or a Chain Reaction?
Last year, two major earthquakes—one 12 days after the first—shook Mexico. New analysis blames this very unlikely event on chance. But one of the pair may have triggered a third large nearby temblor.
Modeling Megathrust Zones
A recent paper in Review of Geophysics built a unifying model to predict the surface characteristics of large earthquakes.
Scientists Create Catalog of Altotiberina Fault in Italy
More than 37,000 small earthquakes paint a picture of the fault’s behavior and seismic potential.
Robert L. Wesson Receives 2017 Edward A. Flinn III Award
Robert L. Wesson received the 2017 Edward A. Flinn III Award at the American Geophysical Union Fall Meeting Honors Ceremony, held on 13 December 2017 in New Orleans, La. The award honors an “individual or small group who personifies the Union’s motto ‘unselfish cooperation in research’ through their facilitating, coordinating, and implementing activities.”
The Curious Case of the Ultradeep 2015 Ogasawara Earthquake
Unusual ground motion associated with the deepest major earthquake in the seismological record is due to both its great depth and its origin away from the subducting slab.
