AIR Worldwide, the Boston-based catastrophe modeling firm and part of Verisk Inc., said Tuesday it had improved modeling of the extent of damage from conventional bomb blast attacks in its terrorism model for the United States.

The model can help show damage and loss estimates, including property damage and workers compensation, and personal injury, by using the size and location of the bomb, AIR said in its Tuesday statement. Model users can obtain loss results for a specific floor within a structure.

Clients can use AIR’s Touchstone online platform to select a blast size and location to analyze the impact it will have on their specific book of business.

AIR used 3D computational fluid dynamics simulations and incorporated input as recent as from the detonation of a recreational vehicle bomb in downtown Nashville, Tennessee, on Dec. 25, 2020, in developing the model.

Tao Lai, vice president of research for AIR Worldwide, said the updated model can produce a more realistic damage extent for various forms of blast attacks, including the Oklahoma City bombing that was estimated to have had the energy of 4,000 pounds of TNT and damaged 324 structures within a five-block radius.
