U.S. Earthquake Model

The Latest Understanding of Seismic Science and Engineering

Earthquake losses can be very large and uncertain. Based on the latest scientific consensus of earthquake hazard, engineering, and building practices, the U.S. Earthquake Model helps set rational expectations of risk. This robust model offers a comprehensive analytical view to quantify the risk to a specific building or portfolio resulting in the allocation of appropriate pricing and capital reserves.

[NEW] Financial Implications of the HayWired Scenario

A Perspective on the Hayward Fault

The U.S. Geological Survey (USGS) HayWired scenario postulates the occurrence of a magnitude (M) 7.0 earthquake along the fault today. In conjunction with the USGS, CoreLogic® offers a perspective on what this means for the insurance industry—and how we collectively can prepare better.

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.

Features & Benefits
