What are Evidences of Landslide Danger?

There may be signs of landslide danger on a slope or retaining wall before it collapses. Some typical signs of landslide danger are listed below:

1. Landslide debris on roads and footpaths.
2. New large cracks or ground subsidence in slopes, retaining walls or along road pavements.
3. Objects, such as mud, rocks, fragments of concrete/brick and uprooted vegetation, falling from slopes and retaining walls.
4. Sudden change in colour (from clear to muddy) or path of water flowing from slopes or retaining walls.
5. Concentrated water overflowing onto slopes and retaining walls.
6. Cement or concrete surface of slopes bulging or being dislodged or signs of soil erosion underway.
7. Breaking of catchwaters, serious overflow from catchpits or drains.
8. Flooding of water in hilly areas.
9. Sudden increase in seepage over an extensive area of a slope or retaining wall.
10. Listen out for cracking, rumbling or crunching sounds.
