Disaster modeling company AIR Worldwide has updated its terrorism model for the United States to allow for a more complete projection of the extent of damage from conventional bombing.

In a statement, AIR said reinsurers can use their updated terrorism model to estimate the potential property, business interruption, employee compensation and personal injury that can be caused by conventional bomb explosions from acts of terrorism in the United States.

As part of the new model, AIR used three-dimensional simulations to ensure more accurate explosion intensity propagation, reflecting the configuration and proximity of buildings in a variety of urban environments. The updated model also reflects the findings from the detonation of a RV bomb in downtown Nashville, TN on December 25, 2020.

“When terrorists use conventional weapons – the effects of which are typically highly localized – they are likely to target specific buildings or facilities,” said Tao Lai, vice president of research at AIR Worldwide. “The amount of damage that occurs at or near an attack site depends on a number of factors. In addition to the type of weapon used, the surrounding buildings, the building dimensions and the spread of the explosion intensity can have a profound influence on the damage of an attack. “
