STEM foundation of Reinsurance and Catastrophe
The science, technology, engineering and mathematics Reinsurance and Catastrophe rests on. Each method has a canonical page in the STEM Commons, hosted by the Global Centre for Risk and Innovation (GCRI), and a page here on how it is applied in this field.

The STEM methods Reinsurance and Catastrophe applies, and why.
- Extreme value theory in reinsuranceRole in Reinsurance and CatastropheExtreme value theory describes the tail of loss and hazard distributions: how large rare events may be and how uncertain those estimates become beyond the record.
- Actuarial pricing of catastrophe layersRole in Reinsurance and CatastropheActuarial mathematics turns exposure, loss experience and assumptions into reinsurance prices, reserves and capital.
- Climate science for catastrophe riskRole in Reinsurance and CatastropheClimate science explains how warming changes the hazards that drive catastrophe loss.
- Geoscience for earthquake catastrophe riskRole in Reinsurance and CatastropheGeoscience explains earthquakes, volcanic eruptions, landslides and tsunamis.
- Uncertainty in catastrophe modelsRole in Reinsurance and CatastropheUncertainty quantification separates and propagates the uncertainty in catastrophe models: in hazard, vulnerability, exposure and financial terms.
- Hydrology for flood catastrophe modelsRole in Reinsurance and CatastropheHydrology explains how rainfall becomes river and surface water flooding.
- Ocean science for storm surge riskRole in Reinsurance and CatastropheOcean science explains storm surge, sea level rise, ocean warming and tsunami.
- Structural vulnerability for cat modelsRole in Reinsurance and CatastropheStructural engineering explains how buildings and infrastructure respond to wind, ground shaking, flood and fire.
Each Reinsurance and Catastrophe method is described once in the STEM Commons at GCRI and applied here to catastrophe loss, risk transfer and capital.
Grounding makes claims checkable.
When a finding names the methods it depends on, a reader can see its assumptions and limits, and an expert in that method can challenge it.
