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.

【山泥傾瀉跡象逐個睇🔍】⁣ 石敢當曾經介紹過關於斜坡維修嘅資訊畀大家，依家經過斜坡嘅時候有無望多兩眼呢？多啲留意身邊嘅斜坡，有機會及早發現到山泥傾瀉前嘅跡象，咁就可以及時走避，同立刻通知相關業主作出維修，避免意外發生。 石敢當提提大家，斜坡或擋土牆崩塌前可能會出現以下現象： 1：喺斜坡、擋土牆或路面上出現新嘅大裂痕。 2：泥土、岩石，混凝土或磚石碎塊及連根拔起嘅植物等，從斜坡及擋土牆墮下。 3：馬路及行人徑上有塌下嘅泥石。 4：從斜坡及擋土牆流出嘅水，突然改變顏色，由清澈變成泥濁。 除咗以上呢啲常見跡象，喺大雨過後行近斜坡或擋土牆，如果聽到一啲奇怪嘅聲音，例如係破裂聲、隆隆聲或壓碎聲，要盡快遠離佢哋，因為呢啲聲都有可能係其中一個山泥傾瀉前跡象嚟㗎。 記得Follow埋GEO Channel 土力場，知道更多資訊：https://bit.ly/2WIIWTY #定期斜坡維修 #雨後斜坡檢查 #geochannel #土力場
