Geologists Use Radioactive Clock to Document Longest Earthquake Record

University of Wisconsin-Madison

Using radioactive elements trapped in crystallized, cream-colored “veins” in New Mexican rock, geologists have peered back in time more than 400,000 years to illuminate a record of earthquakes along the Loma Blanca fault in the Rio Grande rift. It is the longest record of earthquakes ever documented on a fault.

A Seismic Mapping Milestone

Oak Ridge National Laboratory

Using advanced modeling and simulation, seismic data generated by earthquakes, and one of the world’s fastest supercomputers, a team led by Jeroen Tromp of Princeton University is creating a detailed 3-D picture of Earth’s interior. Currently, the team is focused on imaging the entire globe from the surface to the core–mantle boundary, a depth of 1,800 miles.

Using a Method From Wall Street to Track Slow Slipping of Earth’s Crust

University of Washington

An algorithm for stock prices can be used with GPS data to automatically detect slow-slip earthquakes at a single station, offering a new way to monitor seismic activity.

Sinking of Seal Beach Wetlands Tied to Ancient Quakes

California State University, Fullerton

When geologists went in search for evidence of ancient tsunamis along Southern California’s coastal wetlands, they found something else. Their discoveries have implications for seismic hazard and risk assessment in coastal Southern California.

Fault System Off San Diego, Orange, Los Angeles Counties Could Produce Magnitude 7.3 Quake

University of California San Diego

The Newport-Inglewood and Rose Canyon faults had been considered separate systems but a new study shows that they are actually one continuous fault system running from San Diego Bay to Seal Beach in Orange County, then on land through the Los Angeles basin.

SDSC Achieves Record Performance in Seismic Simulations with Intel

University of California San Diego

Researchers at the San Diego Supercomputer Center (SDSC) at the University of California San Diego have developed a new seismic software package with Intel Corporation that has enabled the fastest seismic simulation to-date, as the two organizations collaborate on ways to better predict ground motions to save lives and minimize property damage.

Release of Water Shakes Pacific Plate at Depth

Washington University in St. Louis

A team of seismologists analyzing the data from 671 earthquakes that occurred between 30 and 280 miles beneath the Earth's surface in the Pacific Plate as it descended into the Tonga Trench were surprised to find a zone of intense earthquake activity in the downgoing slab. The pattern of the activity along the slab provided strong evidence that the earthquakes are sparked by the release of water at depth.

Future ‘Smart Cities’ Should be Super-Connected, Green and Resilient

Rutgers University

When Superstorm Sandy lashed New Jersey in 2012, Narayan B. Mandayam lost power in his East Brunswick home for five days. Sandy sparked the Rutgers professor’s interest in helping to engineer smart cities, where everything is connected; renewable energy, green infrastructure and sustainability reign; and resilience after breakdowns, disasters and malicious attacks is critical.

A Tectonic Shift in Predicting Earthquakes, Volcanic Hazards

University of Delaware

A recent study by the University of Delaware's Jessica Warren and colleagues at two other universities provides a new data set that scientists can use to define a tectonic plate and predict future earthquake and volcanic hazards, where they might occur and how deep the devastation might be.
