Going deep: new ground motion model more accurately simulates earthquakes, explosions
LLNL scientists have created a new adjoint waveform tomography model that more accurately simulates earthquake and explosion ground motions. The paper, published in the Journal of Geophysical Research, was selected for an Editor’s Highlight.

LLNL cancer research goes exascale
An LLNL team will be among the first researchers to perform work on the world’s first exascale supercomputer—Oak Ridge National Laboratory’s Frontier—when they use the system to model cancer-causing protein mutations.
