The U.S. Geological Survey is releasing a 3D computer model of the upper 20 miles of the earth’s crust in the greater San Francisco Bay Area that will enable researchers to recreate the shaking levels ...

According to researchers from Science Tokyo, a new three-dimensional model of the fault beneath the Marmara Sea in Turkey reveals where a future major earthquake could take place. Using ...

Three-dimensional fault models are generally more accurate than two-dimensional line models at sending ground shaking alerts to the correct areas as part of an earthquake early warning system, ...

Velocity is a fundamental property of rocks that depends on density and elastic moduli. It varies laterally as well as vertically due to the physical-geologic variations of rocks. Velocities are ...
