Dark Fiber Lays Groundwork for Long-Distance Earthquake Detection and Groundwater Mapping

Researchers at Berkeley Lab have turned parts of a 13,000-mile-long testbed of “dark fiber,” unused fiber-optic cable, owned by the DOE Energy Sciences Network (ESnet) into a highly sensitive seismic activity sensor that could potentially augment the performance of earthquake early warning systems currently being developed in the western United States.

Climate Simulations Project Wetter, Windier Hurricanes

New supercomputer simulations by climate scientists at Lawrence Berkeley National Laboratory have shown that climate change intensified the amount of rainfall in recent hurricanes such as Katrina, Irma, and Maria by 5 to 10 percent. They further found that if those hurricanes were to occur in a future world that is warmer than present, those storms would have even more rainfall and stronger winds.

DOE to Build Next-Generation Supercomputer at Lawrence Berkeley National Laboratory

The U.S. Department of Energy announced today that the National Energy Research Scientific Computing Center (NERSC) at Berkeley Lab has signed a $146 million contract with Cray for the facility’s next-generation supercomputer, a pre-exascale machine slated to be delivered in 2020. Named “Perlmutter” in honor of Nobel Prize-winning astrophysicist Saul Perlmutter, it is the first NERSC system specifically designed to meet the needs of large-scale simulations as well as data analysis from experimental and observational facilities.
