DRRR Q4 MODULE 1

• A gradual or sudden natural earth processes which cause injury, loss of life, property damage, loss of livelihood and services, social and economic disruption, or environmental changes which include earthquakes, landslides, volcanic eruption, sinkholes etc.. - Geological Hazards
• A rock, dirt, or debris falling down a sloping section of land caused by storms, earthquakes, volcanoes or other factors which makes the slope unstable. - Landslide
• Three major causes of landslides- Geology, Morphology, Human activity
• A major cause of landslide that refers to the material of the soil or rock in the area or can be the layers of earth has weakened or stiffened in some part. - Geology
• A major cause of landslide that refers to the structure of the land. The soil or rock has weakened through loss of vegetation or root system which holds the soil in place. - Morphology
• A major cause of landslide which refers to make way for agriculture and construction, trees are needed to be cut down. Irrigation, deforestation, and excavation can weaken the integrity of the earth. - Human Activity
• This is the most common landslide we have experienced here in the Philippines. - Rainfall-induced Landslide
• This landslide occurs due to prolonged or heavy rainfall, increasing the weight of the land mass. The development of this landslide may take several days but the landslide itself will only take a few minutes to cause a disaster. - Rainfall-induced Landslide
• This kid of landslides can form debris flows when they mix with additional water and sediments from their path. It may sweep away a whole community in an instant. - Rainfall-induced Landslide
• What kind of Landslide are these given impending signs? Rainfall-induced Landslide

  • Unusual noises, such as breaking trees, or knocking boulders together, can mean moving debris.
  • As the landslide nears, a slight rumbling sound that rises in amplitude is noticeable.
  • Rapid rise in water levels of the creeks, likely followed by increased turbidity (soil content).
• What does EWS stand for? Early Warning System
• What does PHILVOCS stand for? Philippine Institute of Volcanology and Seismology
• What does PAGASA stand for? Philippine Atmospheric, Geophysical and Astronomical Services Administration
• Give the three abbreviation of the monitoring systems designed to forecast events accompanying landslides in order to provide a warning about hazards. EWS, PHIVOLCS and PAG-ASA
