This article originally appeared at lbl.gov and was authored by Jessica Scully. Researchers at Berkeley Lab are using high-performance computing systems to better predict how structures will respond to an earthquake along one of the Bay Area’s most dangerous faults. Berkeley Lab researcher David McCallen David McCallen is the principal investigator of a team of…

Induced seismicity refers to typically minor earthquakes and tremors triggered by human activity, deliberate or not. Rarely are humans aware of these mostly low-magnitude events occurring deep underground. However, some regions have over the past decade shown quite significant earthquakes, such as a few larger than magnitude 5 events in Oklahoma, which have been linked to wastewater injection…

ABOVE: Images resulting from recent simulations at NERSC show the distribution of ground motion intensity across the San Francisco Bay Area region 10 and 15 seconds after a large-magnitude earthquake along the Hayward Fault. (Credit: Berkeley Lab) With unprecedented resolution, scientists and engineers are simulating precisely how a large-magnitude earthquake along the Hayward Fault would…

EESA Scientists were able to use the new synchrotron Infrared Nano Spectroscopy (SINS) capability at Advanced Light Source. Above: Diagrams of the setup of (a) the Germanium-hemisphere enhanced attenuated total reflection (Ge micro-ATR) and (b) the resonance enhanced SINS. Berkeley Lab scientists have identified a way to use machine learning to connect fine- and large-scale…

Scientists from the Energy Geosciences Division at Lawrence Berkeley National Laboratory (LBNL) have released the latest version of TOUGH (Transport Of Unsaturated Groundwater and Heat), a suite of software codes used worldwide to simulate nonisothermal multiphase flow and transport in fractured and porous media. TOUGH3 builds on the impressive legacy of its TOUGH predecessors, which…

New research from the Energy Geosciences Division at Berkeley Lab shows that carbon dioxide can penetrate the inner layers of some non-swelling clay minerals which make up the dominant clays in the Earth's deep subsurface. Results of the work performed at the Center for Nanoscale Controls on Geologic CO2 (NCGC) and the national lab’s Molecular Foundry could help inform practices intended to help limit carbon dioxide emissions, such as carbon capture and storage (CCS) and enhanced oil recovery (EOR).

A research team led by Kurt Nihei, a staff scientist in the Energy Geosciences Division of Berkeley Lab, has received a funding award through the lab’s Laboratory Directed Research and Development program. Over the next two years, the researchers will collaborate with Pacific Gas & Electric to evaluate the ability of next-generation electric meters to assess regional seismic risk.
