- A dam-age function is defined as the mathematical relation between the magnitude of a (natural) hazard and the average damage caused on a specific item (building, person, etc.) or portfolio of items.

What is a damage function in hazard assessment?
What is a unified damage function?
Are damage functions available for different hazards?
Damage functions are an important tool for an impact assess-ment of climate-related hazards. For example, Fig.1shows three damage functions that relate to the hazards of coastal flooding, wind storms, and excessive heat. It is the goal of this section to determine a unified damage function that has applicability in each of these fields.

Burke et al (2015 and 2018) do not define a damage function but instead show curves of damage vs. temperature change. Accordingly, we digitized the graphs and assessed regression analyses Ω with cubic, quadratic, and linear equations for Ω = Damage function = 1-1/(1+D).
A climate damage function is a simplified expression of economic damages (which theoretically can encompass both positive and negative effects) as a function of climate inputs, such as changes in temperature.

Apr 24, 2017 · In catastrophe models, damage functions translate the intensity of a hazard affecting a structure (ground shaking, wind speed, water depth, etc.) to a damage ratio, which is the ratio of the repair cost of a building to its replacement value (cost to rebuild the entire structure).
In the context of a catastrophe model, damage functions translate the intensity of the hazard affecting a structure or portfolio of structures into monetary losses before any risk sharing arrangements (e.g., insurance contracts) are taken into account.
