1. A disaster predicting method of sequentially executing:
- a step of sending, when an attribute value of a periodically observed or predicted natural phenomenon exceeds a predetermined threshold, a delivery request for satellite image data of remotely sensed natural phenomenon related to said attribute value in an area including a location where said attribute value is observed or predicted;
a step of extracting, when delivery of the satellite image data related to said delivery request is received, disaster predicted areas which are predicted to have disasters caused by natural phenomenon related to said attribute value, based on differential image data between said satellite image data and standard satellite image data;
a step of calculating an index showing the risk of said disaster, for each of the extracted disaster predicted areas, based on attribute values of respective pixels which constitute said differential image data; and
a step of notifying of a possibility of said disaster in said disaster predicted area, when said index exceeds a predetermined threshold.
