Accurate, Impactful Catastrophe Models

Increasing uncertainty and more frequent catastrophes are putting your company to the test. Your risk managers have to prepare for a mind-boggling array of perils.

Having accurate, high-quality models is essential. For more than 30 years, that has been a specialty of RMS. Our approach makes all the difference.

Watch Mohsen Rahnama, PhD, CRMO, and EVP of RMS Model Development, discuss the art of building the best models in our Models, Experts, and Coffee series.

What is Catastrophe Modeling

What is Catastrophe Modeling?

Catastrophe modeling allows insurers and reinsurers, financial institutions, corporations, and public agencies to evaluate and manage natural catastrophe risk from perils ranging from earthquakes and hurricanes to flood and wildfire.

Just because an event hasn’t occurred in the past doesn’t mean it can’t or won’t. A combination of science, technology, engineering knowledge, and statistical data is used to simulate the impacts of natural and man-made perils in terms of damage and loss.

Catastrophe Modeling Framework

The basic framework for modeling the impacts of natural hazards on building inventories can be broken down into the following four modules:

Stochastic Event Module

The first stage of catastrophe modeling begins with the generation of a stochastic event set, which is a database of scenario events. Each event is defined by a specific strength or size, location or path, and probability of occurring or event rate. Thousands of possible event scenarios are simulated based on realistic parameters and historical data to probabilistically model what could happen over time.

Hazard Event Module

The hazard module assesses the level of physical hazard across a geographical area at risk. For example, an earthquake model estimates the level of ground motion across the region for each earthquake in the event set, considering the propagation of seismic energy. For hurricanes, a model calculates the strength of the winds around a storm, considering the region’s terrain and built environment.

Vulnerability Module

The vulnerability module assesses the degree to which structures, their contents, and other insured properties are likely to be damaged by the hazard. Because of the inherent uncertainty in how buildings respond to hazards, damage is described as an average. The vulnerability module offers unique damage curves for different areas, accounting for local architectural styles and building codes.

Financial Module

The financial module translates the expected physical damage into monetary loss. It takes the damage to a building and its contents and estimates who is responsible for paying. The results of that determination are then interpreted by the model user and applied to business decisions.

Raising the Bar in Catastrophe Modeling

Curiosity, passion, and innovation make high-quality models.

Having the best models is key to enable the (re)insurance industry to make crucial decisions. Models inform insurers how to manage risk aggregations, deploy capital, and price insurance coverage. It also allows insurers to demonstrate capital adequacy to rating agencies.

Pillars of High-Quality Models

RMS is on a continuous quest to build high-quality models using the best available data, science, people, and technology.
