AIR earthquake models leverage local and regional expertise to represent the most advanced understanding of seismic hazard and building vulnerability. Our models help you better prepare for the financial consequences of catastrophic earthquakes.


Get a comprehensive view of seismic hazard.

Because relying on historical records alone is insufficient for estimating where future earthquakes will occur and how large they will be, AIR models also use information from extensive GPS networks to provide insight into where and how seismic stress is accumulating.

Appropriately account for loss volatility.

The models capture the frequency and magnitude of "tail" scenarios—infrequent events that cause large losses—as well as low loss periods, both of which contribute to estimates of average annual loss.

Evaluate impacts of related sub-perils.

In regions where they are significant drivers of loss, AIR earthquake models include separate damage functions for tsunami, liquefaction, fire following, and landslide, in addition to ground shaking caused by earthquakes.

High-resolution soil maps reflect potential for ground motion amplification.

Detailed maps reveal varying soil types near exposures, which can dramatically alter the intensity of ground shaking at a site and differ greatly within regions.

Capture regional differences in vulnerability.

AIR earthquake models are informed by region-specific construction practices and building codes, damage surveys, and engineering research to more accurately reflect the variability of the building stock.
