For cat and analytics teams

An open alternative to your vendor models

Your analysts can run open catastrophe models as often as they need and compare them with the vendor models you already use.

Same storms, two published damage curves

10,000 simulated years

  • LocationsMiami, Houston, New Orleans
  • Emanuel (2011)$13,672 a year · 1-in-100 $369,776
  • Eberenz et al. (2021)$6,664 a year · 1-in-100 $179,714
  • Run idlab-climada-storm:df5dab0ff0f6c19a
The same simulated storms run with two published damage curves. Switching from Emanuel to Eberenz roughly halves the loss.

How teams use it

How cat teams use Craton

  1. Run the open models

    Run CLIMADA, OpenQuake, Oasis, ESRM20 and the open flood and wildfire maps on your portfolio.

  2. Compare results

    See average annual loss, exceedance curves and return-period losses next to your vendor model’s results.

  3. Build your own

    Build a model from public data and run it through the API.
