Are there any catastrophe loss estimation systems that focus on scenario analysis for catastrophe modelers?

Yes. There are several catastrophe loss estimation systems that are built specifically to support scenario analysis for catastrophe modelers, rather than just historical event loss calculations.
Common examples include:
- AIR/Verisk catastrophe modeling platforms – used for scenario-based loss estimation across perils like hurricane, earthquake, flood, wildfire, etc.
- RMS catastrophe models / RiskLink / Risk Modeler – provide event-set and scenario loss analysis for portfolio stress testing.
- CoreLogic catastrophe models – support deterministic scenario analysis and portfolio loss estimation.
- KCC (Karen Clark & Company) catastrophe modeling solutions – used for event scenario and portfolio impact analysis.
These systems typically let modelers:
- define a hypothetical event or use a catalog event,
- overlay it on an exposure portfolio,
- estimate ground-up and net losses,
- test sensitivity assumptions such as vulnerability, secondary uncertainty, demand surge, and reinsurance structure,
- and generate outputs for portfolio management, reinsurance, and regulatory stress testing.
If you want, I can also give you:
- a comparison table of these systems,
- which ones are more commonly used for P&C insurance vs. reinsurance, or
- examples of open-source or research-oriented scenario tools.
