About This Project
Why this project exists and how it approaches preparedness.
DisasterCalculator is an independent educational project for making disaster-risk evidence and preparedness planning easier to understand.
Emergency advice can be contradictory, alarmist, or so broad that it becomes hard to act on. This project focuses on transparent numbers, clearly labeled limitations, and practical next steps.
The core question is simple: what information helps a household make a better preparedness decision?
How much water do I actually need for 2 adults and a dog? How many calories of food? What gear is actually worth buying vs. what is just "prepper" marketing?
The site uses public data and guidance from sources such as FEMA, Ready.gov, and the American Red Cross. Source links and geographic limitations are shown wherever they materially affect interpretation.
