“Mass Movement is defined as the downslope movement of rock and regolith near the Earth’s surface mainly due to the force of gravity. Mass movements are an important part of the erosional process. It moves material from higher elevations to lower elevations where transporting agents like streams and glaciers can then pick up the material and move it to even lower elevations. Mass movement processes occur continuously on all slopes; some act very slowly, others occur very suddenly, often with disastrous results. Any perceptible down-slope movement of rock or regolith is often referred to in general terms as a landslide. Landslides can classify in a much more detailed way that reflects the mechanisms responsible for the movement and the velocity at which the movement occurs.”
Types of Mass Movement Hazards are:
Slope Failures is a sudden failure of the slope resulting in the transport of debris downhill by sliding, rolling, falling, or slumping. For instance, when a rocky mountain has a road beside the bottom of the hill, motorists can be a hazard. This is due to inevitable rocks falling from the hill. The possible solution for this can be a high barrier and signage for the traffic.
Sediment Flows – debris flows downhill mixed with water or air. For instance, in Asian countries, especially in tropical weather like the Philippines, we sometimes have a longer time of rain than in western countries like the U.S.A. In this situation, when the rain stops for 3-4 days, soil in the forest is getting soft and can cause landslides. However, planting trees can prevent them from softening. Furthermore, slash-and-burn or “Pagkakaingin” in the Philippines is high contained in the Philippines. Slash-and-burn is the process of burning some forest for agricultural interest.
