Abstract
Moisture content information in soil at a specified site, and moisture content information at a ground surface within a given range that includes the specified site, are acquired. A point where there is a risk of natural disaster within the given range is determined and highlighted, based on the moisture content information in soil at the specified site and the moisture content information at the ground surface within the given range.
Claims6
A disaster prediction method comprising:
- acquiring moisture content information in soil at a specified site;
- acquiring moisture content information at a ground surface within a given range that includes the specified site;
- determining and highlighting a point where there is a risk of natural disaster within the given range based on the moisture content information in soil at the specified site and the moisture content information at the ground surface within the given range;
- calculating a storage volume of water on the ground surface or in a ground at a freely-selected site in the given range based on the moisture content information in soil and the moisture content information at the ground;
- calculating a degree of risk of a landslide disaster at the freely-selected site in the given range based on the storage volume of water on the ground surface or in the ground at the freely-selected site in the given range, a slope stability analysis formula, and the relationship between other variables required for the slope stability analysis formula, the landslide disaster being included in the natural disaster;
- and
- determining and highlighting a point where there is a risk of the landslide disaster within the given range based on the degree of risk of the landslide disaster at the freely-selected site in the given range.

A disaster prediction system comprising:
- at least one processing component configured to:
- acquire moisture content information in soil at a specified site;
- acquire moisture content information at a ground surface within a given range that includes the specified site;
- determine and highlight a point where there is a risk of natural disaster within the given range, based on the moisture content information in soil at the specified site and the moisture content information at the ground surface within the given range;
- calculate a storage volume of water on the ground surface or in a ground at a freely-selected site in the given range based on the moisture content information in soil and the moisture content information at the ground;
- calculate a degree of risk of a landslide disaster at the freely-selected site in the given range based on the storage volume of water on the ground surface or in the ground at the freely-selected site in the given range, a slope stability analysis formula, and the relationship between other variables required for the slope stability analysis formula, the landslide disaster being included in the natural disaster;
- and
- determine and highlight a point where there is a risk of the landslide disaster within the given range based on the degree of risk of the landslide disaster at the freely-selected site in the given range.

- processing of determining and highlighting a point where there is a risk of natural disaster within the given range based on the moisture content information in soil at the specified site and the moisture content information at the ground surface within the given range;
- processing of calculating a storage volume of water on the ground surface or in a ground at a freely-selected site in the given range based on the moisture content information in soil and the moisture content information at the ground;
- processing of calculating a degree of risk of a landslide disaster at the freely-selected site in the given range based on the storage volume of water on the ground surface or in the ground at the freely-selected site in the given range, a slope stability analysis formula, and the relationship between other variables required for the slope stability analysis formula, the landslide disaster being included in the natural disaster;
- and
- processing of determining and highlighting a point where there is a risk of the landslide disaster within the given range based on the degree of risk of the landslide disaster at the freely-selected site in the given range.
