Earth Structure
Figure Caption: Seismic tomography images for the structure below the Long Valley Caldera in California. The panels on the right show the vast improvement to the resolution of the images using data from fiber optic sensing (DAS).
Seismo Lab scientists are actively mapping out the structure of the Earth's interior at all depths, including the crust, mantle, and core. We are pushing the envelope to develop new observational capabilities with dense seismic networks (using low-cost sensors and fiber optic cables) as well as new inversion methods using tomography and machine learning. Southern California, home to the Seismological Laboratory, is a natural seismic laboratory: With abundant seismicity and a nearly century-old high-quality seismic network, SoCal is ideal for imaging subsurface geology and testing new seismic sensing technologies. We are also using dense sensor networks around the world, such as in Japan and deploying our own sensors in active tectonic regions, such as in Iceland, as well as on ice sheets, such as at the South Pole.
