<p><b>New page</b></p><div>🖥️ '''Catastrophe modeler''' refers to a professional — or, by extension, the firm — that builds, runs, and interprets [[Definition:Catastrophe modeling | catastrophe models]] to quantify the potential [[Definition:Loss | losses]] an [[Definition:Insurance carrier | insurer]], [[Definition:Reinsurer | reinsurer]], or [[Definition:Insurance-linked security (ILS) | capital-markets investor]] may face from extreme events such as hurricanes, earthquakes, floods, and wildfires. Within the insurance industry, the major commercial catastrophe modeling firms — [[Definition:Moody's RMS | Moody's RMS]], [[Definition:Verisk | Verisk (AIR)]], and [[Definition:CoreLogic | CoreLogic]] — provide the foundational software platforms, while individual catastrophe modelers at carriers, brokers, and consulting firms customize and apply these tools to specific portfolios.<br />
<br />
🔬 A catastrophe modeler's day-to-day work spans data engineering, hazard science, and financial analysis. They ingest an insurer's [[Definition:Exposure | exposure]] data — including property locations, construction types, [[Definition:Total insured value (TIV) | insured values]], and policy terms — and run it through model components that simulate hazard intensity, estimate physical damage via [[Definition:Vulnerability function | vulnerability functions]], and translate damage into financial losses after applying [[Definition:Deductible | deductibles]], [[Definition:Policy limit | limits]], and [[Definition:Reinsurance | reinsurance]] structures. The outputs — [[Definition:Exceedance probability curve | exceedance probability curves]], [[Definition:Average annual loss (AAL) | average annual losses]], and [[Definition:Tail value at risk (TVaR) | tail metrics]] — feed directly into [[Definition:Underwriting | underwriting]] decisions, [[Definition:Reinsurance | reinsurance]] purchasing strategies, [[Definition:Rate filing | rate filings]], and [[Definition:Rating agency | rating-agency]] evaluations.<br />
<br />
🌍 As [[Definition:Climate risk | climate risk]] reshapes the frequency and intensity of natural perils, catastrophe modelers have become some of the most strategically influential voices in insurance. Their analyses determine how much [[Definition:Premium | premium]] carriers collect, how much [[Definition:Capital | capital]] they hold, and where they are willing to write business. The profession is evolving rapidly — incorporating [[Definition:Machine learning | machine learning]], real-time [[Definition:Remote sensing | satellite data]], and higher-resolution climate projections — and the demand for skilled modelers continues to outpace supply across [[Definition:Insurance market | primary insurers]], reinsurers, [[Definition:Insurance broker | brokers]], and [[Definition:Insurtech | insurtech]] startups alike.<br />
