  • Geologic Hazards
    • extreme natural events in the crust that will create a treat for humanity or any living things.
    • some examples of these geological hazards are earthquakes, volcanic eruptions, and more.
  • Landslide
    • the movement of debris rocks or any particles in the earth in the downslope.
  • Rainfall-induced Landslide
    • a type of landslide which comes with water in it so aside from debris and rocks it also has water due to heavy RAINFALL.
  • Sinkhole
    • naturally occurring geological hazard below the surface that collapse eventually some geologist called it “karst terrain” a specific type of terrain that is from due to dissolving of rock beneath the surface.
    • limestone is the most common type of rock that is dissolved
  • Types of Sinkhole
    1. Solution Sinkhole
    2. Cover Collapse Sinkhole
    3. Cover Subsidence Sinkhole
  • Solution Sinkhole
    • the most common sinkhole it formed when the soil is very thin on the surface and exposing the bedrock once it starts to rain the soil are carried out and eventually leaving a hole.
  • Cover Collapse
    • most dangerous type of all the sinkholes happened when water penetrates in the topsoil going to the limestone and dissolve it eventually until the surface collapse.
  • Cover Subsidence Sinkhole
    • most common with a surface that semi-permeable
