Modeling Fundamentals: Defining Events in the AIR U.S. Inland Flood Model

With AIR’s U.S. flood event algorithm—which is fine-tuned to work well for the United States, with consideration and review of the country’s meteorological patterns, topographical features, and flood characteristics—insurers can assess and manage their risk from all sources of flooding across the contiguous United States with confidence.

Modeling Fundamentals: Evaluating U.S. Flood Model Loss Output with Historical Loss Experience

Recently, AIR released a major update to our flagship U.S. hurricane model, along with a substantially updated U.S. inland flood model. Both models incorporate the same new pluvial component that uses a physically based 2-dimensional (2D) shallow water wave model to simulate pluvial flood risk over the entire contiguous U.S. These two models also incorporate the same new precipitation-induced flood vulnerability framework. Together, these two models provide a comprehensive view of U.S. flood risk—from both tropical and non-tropical sources on and off the floodplain as well as from storm surge.

Modeling Fundamentals: Re-Evaluating the Seismic Vulnerability of Australia’s Major Construction Types

The 2020 update to the AIR Earthquake Model for Australia provided an opportunity to add support for new risk types and re-evaluate the modeled vulnerability for property in Australia. Cavity double brick masonry and masonry veneer constructions, which constitute the majority of residential buildings in Australia, are used as examples to illustrate this update in light of newly available data from Australia and New Zealand.

Modeling Fundamentals: Why Does Verisk Conduct Post-Event Damage Surveys?

This article focuses primarily on damage surveys conducted in the aftermath of U.S. hurricanes and addresses how and why we conduct them. As we update our U.S. hurricane model—a tool that helps quantify the risk—we uncover more questions that are typically answered only after studying another event.

Modeling Fundamentals: Understanding Tectonic Movement and How It Sheds Light on Seismic Risk

Kinematic modeling techniques use a physical approach to understanding earthquake risk, effectively augmenting the sparse available historical data. AIR Seismologist Dr. Bingming Shen-Tu explains what kinematic modeling is and provides real-world examples in South America, China, Japan, and New Zealand of how effective it is.
