Warning Guidelines

Urge to follow guidelines

Preparing for a potential landslide event is essential to safeguard lives and minimize the impact on communities. Our comprehensive guidelines offer valuable insights on how to stay safe and informed before, during, and after a landslide. By following these guidelines, you can take proactive measures to protect yourself, your loved ones, and your property. From creating an emergency plan to understanding evacuation procedures and post-landslide recovery, our guidelines provide practical steps to help you navigate through this natural hazard. We urged you to follow the following guidelines appropriately.

Action to be taken before the landslide

  •  Avoid constructing buildings adjacent to steep hills, mountain borders, and on drainage paths.
  • Obtain a stability evaluation of your land.
  • Interact with the appropriate authorities, such as the sarpanch or Talati of the village, state geotechnical department or departments of disaster mitigation, and departments of geology to collect information about areas susceptible to landslides and obtain expert recommendations for a comprehensive site examination of your estate.
  • Observe the rainwater drainage which has been passing surrounding your shelter or properties. Also, previously identify where rainstorm meets to form flow channels and avoid visiting such locations when a rainstorm is alive.
  • Be aware of the exit plan of your area for an emergency safe exit. It is also advisable to create your emergency exit plan to evacuate your family members during times of warning.
  • Reduce the risks at your shelter:
  • Use flexible supply fittings at home to safeguard against disasters from gas and water leakage. It must be made such gas fittings from experts/professionals.
  • Grow green cover on slide-prone grounds and construct walls to retain soil flow during landslide events.
  • Build proper levees to channel the debris flow to redirect them into a safe location, which can mitigate the risk during landslide events in areas prone to landslides. 

Action to be taken during a landslide

  • Remain vigilant and conscious. Most fatalities during debris flows happen while people are sleeping. 
  • Keep an ear out for weather warnings via a portable, battery-powered TV or radio. 
  • Take note that brief periods of heavy rain may be more threatening, specifically after an extended duration of a moist environment.
  • If you reside in an area vulnerable to debris flows or landslides, decide to continue to reside only if it is found safe. 
  • Avoid driving vehicles surrounding landslide-prone areas during heavy rainfall, as it may be dangerous to do so. 
  • If you choose to stay home, go to a higher level if feasible. 
  • Avoiding the path of debris flow or landslides can save damage.
  • Observe any unusual noises that may indicate displacement of the slide, like the sound of collapsing trees or accompanying huge noises of boulders. 
  • A tiny initiation of mud or flow of soil may lead to a massive failure of the land slope. Debris can move rapidly and with little alarm.
  • Suppose you find yourself in the surrounding area of a stream of water. In that case, it is vital to remain cautious about any unexpected changes in water flow, such as sudden rises or drops or a shift from clear to shadowy water. These alterations could indicate landslide activity upstream and should serve as a warning. It is necessary to prioritize your safety over material possessions and not hesitate to take necessary action. 
  • When driving, be particularly careful. Roads crossing rivers may be destroyed, and areas may be flooded with stormwater. Advisable not to cross the highly flooded waterway. 
  • Stay away from high elevated highway embankments as they may be particularly prone to failure. 
  • Keep an eye out for any indications of failed pavement of roads, fresh mud, collapsed boulders, and other indication of prominent debris flow.

Action to be taken after the landslide

  • Avoid going near the area affected by the landslide to avoid further danger.
  • Stay updated on the latest emergency information by adjusting to radio stations or television news channels.
  • Be alert for possible floods that may appear after an incidence of the landslide as they may be expected from the landslide event.
  • Look out for injured or blocked individuals surrounding landslides; inform the rescue team to do what is necessary instead of self-entering into the slide area.
  • Assist fellow citizens who require special attention like infants, aged persons, or disabled persons. 
  • Inform the appropriate authorities about any damage observed to utility lines and transport ways to avoid further injury.
  • Examine your building's footing, smokestack, and the nearby ground for any injury to ensure the safety of the area.
  • Do replantation on the damaged ground after a landslide event to prevent erosion and landslides in the future.
  • Consult a geotechnical specialist for guidance on examining landslide damages and for deciding on design steps for rehabilitation of the area. A professional can provide the best advice on how to prevent or minimize landslide risk.

If you are alarmed about the likelihood of a threatening landslide, there are certain steps you can take to protect yourself and your loved ones

  • Seek assistance from your village's public workers, police, or fire department to evaluate any potential risks.
  • Notify neighboring residents of potential hazards so that they are aware and can take precautions to protect themselves and evacuate if necessary.
  • Evacuate the area rapidly if advised to do so by officials or if you feel at risk.
  • If escaping is not feasible, assume a fetal position and shield your head to protect yourself from harm.

Warning signs of a landslide

  • Recognizing the warning signs of an impending landslide can be critical in taking swift action and ensuring personal safety. Our dedicated section on warning signs equips you with the knowledge to identify potential indicators of a landslide. Understanding changes in the landscape, such as slope deformation, cracking, or sudden water drainage, can help you stay vigilant and take the necessary precautions. By familiarizing yourself with these warning signs, you can play an active role in early detection and response.

  1. Noticeable water storage in normally dry areas, such as saturated ground.
  2. New or unusual ground features, such as wide cracks and bulges in the ground
  3. Movement of soil away from structures and tilting or displacement of ancillary structures like decks and patios with respect to rigid construction.
  4. Signs of damage to concrete structure connected to ground, such as tilting or cracking.
  5. Damage to underground utilities such as water lines, displacement of trees & retaining walls, and tilting of an electrical pole.
  6. Damages to the alignment of boundary lines and settlement of ground.
  7. Sudden increase in river water levels, which may contain muddy water, including large soil particles.
  8. Rapid decrease in river water levels besides rainfall is still alive or has recently paused.
  9. Wooden frames of entrance that are difficult to open or close and visible gaps that indicate that the frames are out of plumb.
  10. A diminished roaring sound that rises in volume as the landslide approaches.
  11. Abnormal noises such as cracking trees or knocking large rocks may indicate slide movement.

List of areas that are highly prone to landslide events

  • Awareness of areas highly susceptible to landslide events is crucial for individuals and communities residing in these regions. Our comprehensive list provides valuable information about locations prone to landslides. By understanding the geological and environmental factors that contribute to landslide occurrence, you can make informed decisions about where to live, build infrastructure, or plan recreational activities. This list serves as a valuable resource in promoting awareness and assisting in risk assessment for areas susceptible to landslides.

  1. Areas on the same topography as old landslides.
  2. Ground of slopes and their base
  3. In the vicinity of drainage hollows.
  4. Aged fill slope
  5. Slopes that are made of steep cuts.
  6. Developed slopes at which a leach septic system is employed.
  7. Hilly range with the possibility of prolonged rainfalls
  8. Hill slopes with inappropriate drainage of water
  9. Hill slopes with manmade alteration, such as cutting off the toe of the hill.
