    • By using information collected on-site, estimation of a damage area at that time and also prediction regarding subsequent expansion of a disaster-affected area are performed. Provided is a disaster-affected area estimation device (10) for performing estimation of a disaster-affected area when a disaster occurs, including a storage unit (21) that stores an exposure calculation formula expressing an exposure amount, which is an integrated value of the concentration of a material with respect to time, at a certain time and a certain position, by using the diffusivity and flow rate of the material; an information-acquisition unit (22) that acquires position information of disaster victims at a prescribed time as input information; and a calculation unit (23) that obtains a critical value of the exposure amount by applying the position information of each disaster victim at the prescribed time to the exposure calculation formula and that specifies the disaster-affected area at the prescribed time on the basis of the exposure calculation formula for when the critical value is obtained.
