Mass Wasting

Mass Wasting Week:8


According to the book landslides are a comprehensive term in which any type of downslope movement of earth materials, which in stricter sense, mass wasting refers to a rapid downslope movement of rocks or soil as a more or less coherent mass. There are many types of mass wasting and downslope such as rock fall, slump, soil slip, rock slide, avalanche, creep, earthflow, debris flow, and complex which depend on the area of the situation (217).  Driving and resisting forces are not static because as local conditions change, these force are likely to change, increasing or decreasing the safety factors, which determine the variables of type of earth materials, slope angle and topography, climate, vegetation, water and time all account for in the environment. 



According tp BBC news article dozens of people dead in Pakistan and India after landslide and flooding in 2016. At least 58 people are reported killed in the northern Pakistan and India by flash floods which occurred with monsoon rain falls and which triggered landslides. But I will be focusing on Pakistan. hundreds of people die in southern and northern parts due to monsoon raining flood seasons. A flash flood hit the village of chitral overnight, several people were praying in the local mosque and some were sleeping that were killed. The country was in panic, rescuers deployed as soon as they could but sadly late to save many lives. Personally I who have lived in Pakistan and in  first hand has experience how poor some villages are and have visited them.  How poorly the road, building structures and how the area is near a larger lake or river which can be a risk.
 To prevent mass wasting in parts of Pakistan personally I think in order to protect people the government should invest in the sewer system to prevent a flood from happening and loosening up the ground. Personally the Pakistan government only cares when a massive death toll due to a mass wast affects them. I couldn't find anything that related to preventing mass wasting besides rescuring people when its really serious.
