Seismic attenuation techniques reveal what lies beneath Taiwan‎

As seismic waves travel through Earth, they gradually lose energy, a process called attenuation. That energy loss doesn't happen uniformly—some features in the crust sap far more energy from seismic waves than others. Researchers can map underground features by watching where seismic waves lose more or less energy. The Southern Array for the Lithosphere and Uplift of Taiwan Experiment (SALUTE) is doing just that, providing information that could lead to improved seismic hazard planning in the country.
