The core idea behind catastrophe modeling is that the architecture of risk quantification is the same whatever the peril. While a hurricane is not an earthquake, building a hurricane catastrophe model has elements in common with an earthquake catastrophe model. Stochastic event occurrence, the hazard footprint, the damage mechanism, clustering, post-event loss amplification are all shared concepts.
While on the university campus, disciplines may retain their nineteenth century segregations, in catastrophe modeling we are “ecumenical” about what is the driver of loss: whether it is wind, hail, vibration, flood, cyber, a virus or a terrorist attack. The track of a hurricane, the track of a fault rupture: the contagion of influenza, the contagion of NotPetya malware: the topographic controls of flooding, the topographic controls of wildfire. Exploring the parallels can be illuminating.
Which is why it is interesting to discover historical figures, who like catastrophe modelers, have looked sideways across the catastrophe disciplines. One such figure is the Anglo-Greek Lafcadio Hearn (unless you are from Japan where he is known as Koizumi Yakumo.)Continue reading
