Los Angeles Basin Passive Seismic Experiment: subsurface imaging in a densely populated urban setting

  • 1. ROR icon California Institute of Technology


Shallow subsurface structures can sometimes focus seismic waves produced by earthquakes, resulting in enhanced earthquake damage. For example, the large amount of damage that occurred in Santa Monica after the Northridge earthquake may have been caused by focusing of seismic energy.
