That is, the storage unit 3 functions as a mesh data storage unit, a disaster warning data storage unit, an information providing program storage unit, and the like. The arithmetic processing means 2 functions as each means described later by executing each process according to the information providing program stored in the storage means 3. The mesh data 10, the disaster alert data 20, and the information providing program are stored in the storage unit 3 through an internet connection or a recording medium. Further, the mesh data 10 and the disaster alert data 20 are configured to be able to be updated through an internet connection or a recording medium.

  As the information providing device 1, for example, mobile terminals such as smartphones and tablets, navigation devices such as stationary and portable, notebook computers and desktop computers can be assumed. In the following description, it is assumed that a smartphone is used as the information providing device 1 and a user of the smartphone is moving by a car.

  FIG. 2 is a functional block diagram of the information providing device 1. As shown in FIG. 2, the information providing device 1 includes mesh data 10, disaster warning data 20, position input means 30, state input means 40, and determination processing means 50.

  As shown in the enlarged view of FIG. 1, the mesh data 10 is a unit grid (hereinafter, simply referred to as a mesh) formed by dividing the land, area, etc. into a grid, and the use of land in that range (house, commerce) It is a database in which information on terrain such as facilities, industrial facilities, cliffs, forests, roads, etc.), altitude, slope, etc. is linked and stored in storage means. The mesh data 10 has map information linked with coordinate positions on the earth, that is, map data that can be displayed on a monitor or the like.

  The disaster warning data 20 is a warning about a plurality of natural disasters provided to the user based on the topography such as the elevation and slope of the land which is a predisposing factor of the disaster and the information such as the state of the natural phenomenon which is a triggering factor of the disaster. It is a database that has been compiled and stored in the storage means. The disaster warning data 20 illustrated in the present embodiment is an example of the state of natural phenomena as the slope of the land as information predisposing to disasters (disaster predisposition information) and information causing disasters (disaster triggering information). It shall be a database which provides a warning about a landslide disaster etc. to a user based on the amount.

  FIG. 3 is a schematic view showing an example of disaster warning data 20 linked to one mesh. Landslide disasters can generally occur under rainfall conditions, for example, when the amount of rainfall per unit time (the amount of rainfall) exceeds a certain value or when the continuous rainfall time is long. Therefore, in the illustrated disaster warning data 20, in response to the rainfall per unit time (the amount of rainfall) and the inclination angle of the land, "heavy rain", "earth and sand disaster warning", "earth and sand disaster evacuation" etc. Alarms are defined.

  In the illustrated example, a specific warning is defined based on the inclination of the land and the amount of rainfall, but not only the amount of rainfall but also cumulative rainfall or a soil rainfall index may be used. In addition to the slope of the land, information on the nature of the soil (for example, water holding capacity) of the land, the use status of the land regarding the presence or absence of afforestation, etc. may be taken into account to define a warning regarding landslide disaster.

  The position input means 30 is a means for inputting position information for specifying from the mesh data 10 the position where the warning regarding the earth and sand disaster is provided to the user. The position input unit 30 can use, for example, a GNSS signal receiver mounted on a smartphone, a telephone call / communication device wirelessly connected to a base station, a touch panel, or the like to enable Internet communication or telephone communication.

  The state input unit 40 is a unit for inputting the state of the natural phenomenon at the position input from the position input unit 30.
