  • Precursor warning signs: river water may become turbid or the water level may suddenly decrease, the ground rumbles, water seeps out from the hillside, trees may tilt, the ground cracks, rocks roll down, etc.
  • Slopes may suddenly collapse, trees uproot and slide down and earth, sand and boulders fall, along with a torrent of mud.
  • Depending on the speed of flow downwards, the destructive force is large and the scope of the disaster is wide.
  • It more frequently occurs on steep slopes, between mountains, developed land or on steep fan-shaped terrain.
  • If the landslide is close to the house, the consequences can be unimaginable and it is highly likely that the home will be involved in being washed away.

The mechanisms of a landslide

Landslides may be caused continuous heavy rainfall, snowmelt or earthquakes.

The timing and magnitude of a landslide depends largely on the geology of the slope, the topography, the vegetation, the rainfall, other hydrological conditions and the degree of seismic activity.

Landslides include boulder falls from cliffs, steep slope cave-in, and mudslides.

Precautionary measures for heavy rainfall and flooding

Check in advance the level of danger near your home or workplace and check with your local disaster prevention map or evacuation map.

Confirm the evacuation routes and places well in advance and record and save them on your cell phone or record note.

Prepare disaster prevention tools in advance, such as sandbags to block doorways to prevent the inflow of large amounts of water and so to reduce the extent of damage inside the house.

Keep backups of your important electronic devices data files in case of water inaccessibility.

Once an emergency warning is issued, take your prepared disaster bag and evacuate immediately to a designated place of safety.

If it is already too late to escape, go to a place above the second floor of your house and contact rescue services and wait.
