About Us

The NEES@UCSB facility consists of permanently-instrumented geotechnical test sites designed to improve our understanding of the effects of surface geology on strong ground motion. The instrumentation at these sites includes surface and borehole arrays of accelerometers and pore pressure transducers designed to record strong ground motions, excess pore pressure generation and liquefaction that occurs during large earthquakes. An instrumented structure is also monitored to improve our understanding of soil-foundation-structure interaction (SFSI) effects.

The NEES@UCSB site is funded in part by the Geoge E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Program of the National Earthquake Hazards Reduction Program (NEHRP) of the National Science Foundation (NSF) under Award Number CMMI-0927178.
