This is the FINAL_RISK_CALC shapefile for running the food and water requirements model, and the FINAL shapefile of results of a practical application of a simplified, deterministic model of initial resource requirements in disaster response, connected with the publication, "A Conceptual Framework for Estimation of Initial Emergency Food and Water Resource Requirements in Disasters" (Toland, J., Wein, A., Wu, A. and Spearing, L, 2023). The model offers a quantitative, comprehensive description of an application within the geophysical hazard context of the “ShakeOut” scenario—a major Mw7.8 earthquake on California’s San Andreas Fault, occurring within the Los Angeles Basin, CA (USA) region. Using the framework as a guide, we illustrate model results that estimate that 999,027 households (2,947,130 residents) will require initial emergency food and water resource requirements (about 3 days after the event). Estimates include 6 million meals and 9 million liters of water, concentrated in Lancaster-Palmdale, El Monte-Baldwin Park, East Los Angeles-Downey in Los Angeles County, the Coachella Valley (Riverside County) and in populated areas of San Bernardino County.
