U.S. Earthquake Model
California Earthquake Authority: Trust Based on Science and Reinforced Through Communication
In the wake of the devastating magnitude 6.7 Northridge earthquake in 1994, the state of California established the California Earthquake Authority (CEA) to educate Californians on how to minimize earthquake losses and to assist insurance companies in setting rates.
Learn why the U.S. Earthquake Model from CoreLogic met the CEA standard—and why it’s still trusted and used today, over 20 years later.
Vulnerability Informed by Engineering
The U.S. Earthquake Model incorporates vulnerability curves that are well-honed from thousands of seismic studies conducted by CoreLogic® and its affiliated engineers over the past 40 years, and are additionally founded on first-hand observations from more than 90 earthquakes worldwide.
Vulnerability is also calibrated to tens of thousands of claims and exposure data points from the Northridge (1994) and Loma Prieta (1989) events.
