25 Years After Loma Prieta: Preparing the Bay Area for "the Big One"

Earthquake risk is on the rise in the San Francisco Bay Area, but earthquake insurance penetration has plummeted since the magnitude 6.9 Loma Prieta Earthquake rocked the region in 1989, causing nearly $6 billion in economic losses. The next Big One could cause losses of over $200 billion. By understanding the potential implications, we can mitigate earthquake risk and ensure resilience in the Bay Area.

Timeline: In the "Big One's" Aftermath

By understanding the stark reality of a hypothetical worst-case earthquake on the San Andreas Fault, we can improve the Bay Area's resilience against the next Big One.

In the 25 years since the Loma Prieta Earthquake, a generation has grown, an industry boomed, population expanded, and residential value skyrocketed. Is the Bay Area prepared for its next major earthquake?

Bay Area earthquake risk is on the rise. And it might not be where you think.

Reddit Science "Ask Me Anything:" A discussion about earthquakes and resilience

Dr. Robert Muir-Wood, RMS chief research officer hosts a Reddit Science AMA (Ask Me Anything) to commemorate the 25th anniversary of the Loma Prieta Earthquake, which rocked California's San Francisco Bay Area on October 17, 1989. The discussion (epi)centers on all things earthquakes—what causes them, how RMS models them, how the next "Big One" could affect the Bay Area, what cities can do prepare, and more—with the Reddit Science community.
