PIXEL LEVEL Multi Hazard Risk Index (MHRI) FOr west coast counties

Subash has created a high-resolution (1 km square pixels) Multi-Hazard Risk Index (MHRI) raster for the 60 coastal counties, across Washington, Oregon, and California.

The MHRI integrates four key components-hazard, exposure, susceptibility, and adaptive capacity.

A raster-approach method that transforms risk assessment from administrative boundaries to a spatially explicit pixel-based system, capturing critical intra-county variations.

This research provides a good alternative/complementing to the current methodology of multi-hazard risk assessment by federal institutions like FEMA where county scale or census tract scale aggregation is done to obtain the risk values.

When hazard and risks are looked at pixel level, we can get better insights for the pixels which could’ve been overlooked in the aggregation method.
