Information gathering

Watch out for cliffs!

A precursor to a landslide

  • Pebbles fall from the cliff.
  • New springs are generated on the slopes.
  • The spring water is turbid.
  • There is a crack in the slope.

Maesho

If you have any of the above precursors, take early evacuation actions.

In addition, there may be no time between the occurrence of a precursory phenomenon and the occurrence of a landslide, or there may be no precursor phenomenon and a landslide may occur.
If you feel danger, take early evacuation action.

Don't overdo it and try to evacuate safely!

When evacuating, wear comfortable clothes and try to act with two or more people.
If the surroundings are dark and flooding has already begun, do not force yourself to go outside and stay at a high place where you can secure safety, such as the second floor of your home.

Evacuate with two or more people

2nd floor or higher


Let's evacuate on a safe route!

  • When evacuating, avoid roads along rivers and cliffs and underground roads.
  • Be careful not to approach the gutters or manholes on the road due to heavy rain.
