Japan emerges from 6.8-magnitude quake unscathed, thanks to resilience

A 6.8-magnitude earthquake almost anywhere in the world would be deadly and destructive. But when a quake that size struck Japan on Saturday, there was only minor damage. Why? Japan’s long history of earthquakes (similar to California’s) has prompted it to take seriously the safety of its buildings. (The 6.7 Northridge quake in 1994 left 60 dead, 9,000 injured and $20 billion in damage.) Japan has learned from its past and taken steps to become more resilient. Find out more in the May 19 Resilience Advantage webinar, where speakers from the National Institute of Building Safety and the University of Southern California explain why our state should do the same.

With earthquakes, size matters — but so does the terrain

Size isn’t all that matters with earthquakes. The ground beneath a structure can also make a difference. “The local geology definitely matters,” said Geophysicist Susan Hough.

Many buildings can benefit from simple seismic improvements

Many buildings can benefit from simple seismic improvements

Safeguarding a building against earthquake damage does not necessarily mean spending an arm and a leg to get the work done. Many old buildings can realize significant improvements in seismic performance with simple, inexpensive improvements. Evan Reis of the U.S. Resiliency Council co-authored this article explaining how.
