Seismic Study Reveals Huge Amount of Water Dragged Into Earth’s Interior

Washington University in St. Louis

Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench.The observations from the deepest ocean trench in the world have important implications for the global water cycle, according to researchers in Arts & Sciences at Washington University in St.

New Model Improves Thermal Models Tying Metamorphic Rocks to Subduction Zones

Boise State University

The temperatures associated with the earth’s subduction zones have been historically miscalculated, which has major implications for our understanding of how the planet’s deadliest earthquakes and volcanic arcs are generated.

‘Majority Rules’ When Looking for Earthquakes, Explosions

Sandia National Laboratories

A dormant volcano in Antarctica helped researchers at Sandia National Laboratories improve sensor data readings to better detect earthquakes and explosions and tune out everyday sounds such as traffic and footsteps. Finding the ideal settings for each sensor in a network to detect vibrations in the ground, or seismic activity, can be a painstaking and manual process. Researchers at Sandia are working to change that by using software that automatically adjusts the seismic activity detection levels for each sensor. Sandia tested the new software with seismic data from the Mt. Erebus volcano in Antarctica and achieved 18 percent fewer false detections and 11 percent fewer missed detections than the original performance of the sensors on Mt. Erebus.

World’s Largest Outdoor Shake Table Receives $16.3M From NSF for Upgrades

University of California San Diego

The world’s largest outdoor earthquake simulator, operated by structural engineers at the University of California San Diego, has received a $16.3 million grant from the National Science Foundation to upgrade the facility to expand its testing capabilities. The funds will enable the simulator, also commonly known as a shake table, to more realistically recreate the motion of the ground during strong earthquakes.

Seismologist works to determine the limit of ground accelerations during earthquakes

Iowa State University

Iowa State's Igor Beresnev has worked summers and weekends to find the answer to a very old question in seismology. Yes, he says, there is a limit to ground accelerations during an earthquake.
