Great California Shake Out! Are you ready?

Oct. 18 1989 Cypruss Overpass Collapse

Today is the Great California Shake Out, a statewide earthquake drill.  Do you know what to do when the Big One comes? 

Ever since the 1989 earthquake and its effects on transportation infrastructure, such as the collapse of the Cypress Freeway (which of course was replaced) or the structural failure of a portion of the San Francisco-Oakland Bay Bridge, there has been considerable research on seismic safety and stability. Are aerial BART stations safe? What are the optimal risk-based maintenance procedures to earthquake safety for bridges and highways?

Of course the Los Angeles region has its own concerns about the Big One, such as the disruption of freight logistics for the mega-region. How will the region's highways be affected? There were lots of lessons learned from the 1994 Northridge earthquake, which help inform projections for future risks.

If you want more research about earthquakes and California transportation, of course turn to TRID. For today, think about what you'd do when the Big One hits and how you prepare for such an event. 

Stay safe.
