Study Notes

  • This module discusses mitigation strategies including preventative measures to avoid loss of lives and properties during natural disasters
  • Landslides and sinkholes are natural disasters that pose physical and environmental threats, causing transportation disruption, property damage, injuries, and fatalities
  • Module equips people with knowledge concerning mitigation strategies that prevents loss of lives and properties

Module Goals

  • Define, identify, and apply mitigation strategies to prevent deaths, injuries, property damage and environmental losses from rainfall-induced landslides and sinkholes
  • Synthesize an action plan involving prevention/mitigation and adaption/preparedness components
  • Value the benefits of understanding planning to reduce the loss of lives and properties

Mitigation

  • Involves acting to reduce the risk of life or property damage from potentially dangerous events
  • Minimizes harm and losses caused by unavoidable natural disasters
  • It's a process or result of making something less severe, dangerous, painful, harsh, or damaging
  • Mitigations are actions taken to prevent or reduce risks to life, social, economic aspects, and natural resources from natural hazards.

Programs to Intensify Hazard Mitigation

  • Protection of schools and hospitals in hazard-prone areas
  • Promoting non-structural measures such as securing furniture to mitigate earthquake injuries and vegetation management to reduce fire damage
  • Incorporating hazard and risk assessment into new developments limiting construction in hazard-prone areas
  • Cultural property preservation of libraries, landmarks, and artistic resources
  • Identifying and protecting valuable natural resources
  • Government leadership to require modern building codes and disaster resilience programs
  • Mitigation training to address contemporary challenges
  • Hazard-specific research is needed to improve mitigation practices

  • Establish a communication plan for separated family members
  • Assemble emergency supply kits for home and car
  • Learn how to shut off appliances
  • Keep resources handy
  • Ensure all family members know these procedures
  • Duplicate important documents and store originals in a safe deposit box
  • Create a detailed inventory of personal belongings with photos or videos

Precautionary Measures for Landslides and Sinkholes

  • Vulnerability and exposure to geohazards are determined through scientific tools, visible signs, and maps
  • Communities are advised to take precautionary measures to prevent unnecessary damage to lives and properties

Steps to Consider Before a Landslide

  • Be familiar with surroundings
  • Watch for any changes to certain objects' presence or positions
  • Sudden debris flow can indicate an incoming landslide
  • Avoid open storm-water drainage and runoff as these areas are likely to receive debris and soil from higher elevations
  • Avoid during storms or heavy rainfall
  • Stay updated on news regarding the condition of your area
  • Be aware of local government disaster plans
  • Learn and participate in emergency response and evacuation plans

Actions During a Landslide

  • Be attentive to unusual signs such as cracking objects and moving debris
  • Stay away from the path of debris, especially dangerous during mudflows
  • Stay alert for sounds indicate moving debris
  • Stay on elevated and sturdy areas
  • Avoid low-lying areas and steep slopes
  • Curl into a tight ball and protect head if escape is not possible
  • Find a structure for protection

Actions After a Landslide

  • Stay away from the slide area due to continued risk
  • Listen for the latest emergency information
  • Follow warnings and instructions from local government
  • Watch out for flooding following rainfall-caused landslides
  • Check for injuries near the slide and flooding
  • Report findings to rescuers/authorities

Sinkholes

  • Also known as cenotes, swallets, swallow holes, or dolines are depressions or holes caused by surface layer collapse
  • Caused by karst processes or chemical dissolution of carbonate rocks
  • Size of the sinkholes vary from 3.3 to 2000 ft
  • Vary in shape from soil-lined bowls to bedrock-edged chasms

Actions to take when Sinkholes Appear Suddenly

  • Find refuge in a stable ground or open area
  • Wait until the structures on and around the sinkhole stops moving
  • Await official announcement

Actions After a Sinkhole's Appearance

  • Stay away
  • Monitor the damages on objects
  • Enlarge sinkholes may still enlarge
  • Do not throw anything that could contaminate groundwater
  • Secure properties and relocate far from the sinkhole's location due to similar soil profiles
