Seismic Isolation - California Academy of Sciences
Seismic isolation is a technique that reduces damage to buildings and their contents in earthquakes.
Learn More About Seismic Isolation
Base isolators are flexible pads or bearings that separate a building from the foundation and therefore reduce the shaking (displacement and acceleration) of the building during an earthquake.

Are There Structures In My Community That Are Base Isolated?
As of 2003 there were more than 200 base isolated buildings and bridges in the United States. Some well known examples are the Golden Gate Bridge, the San Francisco International Airport International Terminal, San Francisco City Hall, Los Angeles City Hall, Pasadena City Hall, and the Utah State Capitol.

NEES focuses on accelerating innovations in infrastructure design and construction practices to minimize damage during earthquakes or tsunamis. Recently, NEES engineers shook a full-scale base-isolated five-story building model on the largest outdoor shake table in the world at UC San Diego. Watch the video!
Our Challenge: Reduce the impact of earthquakes and tsunamis on society through research, engineering, science, and education.
