Cliff selection criteria

[Criteria for Selection of Target Areas]
Based on the results of a survey of cliffs conducted by geological experts, if landslide occurs, it will cause significant damage to houses.
We extracted possible cliffs (*Note 1) and selected them as areas subject to evacuation warning.

(*Note 1) In the event of landslide, damage to buildings close to cliffs and inflow of earth and sand through window glass may occur.
In some cases, cliffs where damage to human life is expected to occur

Specifically,

○Analysis of factors in the landslide, the amount of earth and sand when cliffs collapse, and the magnitude of damage to buildings near cliffs.

◆What is the Factor of landslide?

◆What is the amount of earth and sand when a cliff collapses?
When landslide occurs, the amount of soil that slides off the slope or falls in lumps is classified by size.

◆What is the magnitude of damage to buildings close to cliffs?
If a landslide occurs, it is classified according to the size of the damage.

○Confirm the existence of houses that could cause damage in the event of a landslide, and the distance between cliffs and buildings.
Depending on the height and slope of the cliffs, the area affected by the landslide is set in more detail.
Check if there is any problem.
