Introduction

"What are the physical processes that cause geomorphic hazards? What problems do they cause for people?" The relationship between people and the terrain in which the live on, off and around has been closely co-dependent for thousands of years. In this essay I am aiming to discuss how and the reason how physical processes cause geomorphic hazards, including case studies around the world, where relevant, to show the causes and effects of such hazards. I also want to explain and describe how they have affected the everyday lives of millions of people in every corner of the World. Mass movement processes are the result of physical processes exerted by man (i.e. Farming methods) to natural processes (i.e. Earthquakes). When I talk about mass movement processes, this involves large masses or quantities of land material caused by a number of factors. The factors include: * Erosion by rivers, glaciers, or ocean waves create too steep slopes * Rock and soil slopes are weakened through saturation by snowmelt or heavy rains * Earthquakes create stresses that make weak slopes fail ...read more.

of limestone fell from Turtle Mountain in just 90 seconds. 2. What caused the Frank Slide? Secondary causes were coal mining inside the mountain and weathering. 3. How many people were killed? Of the 600 people living in Frank at the time of the rockslide, approximately 70 were killed. 4. What was destroyed in the slide? There were 7 miner's cottages (6 with people in them) destroyed, a dairy farm, ranch, shoe store, livery stable, cemetery, 2 km of the road and CPR rail line, 3 km of the Frank and Grassy Mountain Railway, a construction camp and all of the surface buildings for the Frank mine. Avalanches occur in mountainous areas all over the world. They occur when a slab of snow is worked loose and slides down a mountain. Although, in many incidences, the weight of a person on the snow can cause a slab of snow to break away and start an avalanche, they also frequently start without any human intervention. ...read more.

Conclusion

Which could then affect the local economy and quality of life as landslides can affect water availability, quantity and quality. With the case studies I have discussed and presented in this essay, and the contrasts of such geomorphic hazards, you can conclude that mass movement processes is one of the most costly and deadly of all hazards as the speed of the landslides is so high that reaction times are very small, meaning higher death rates. With examples from LEDCs and MEDCs, the differences that are apparent are, that many areas in LEDCs are over-crowded and the poor housing and conditions do not help. For example with the Mamayes, Puerto Rico incident, the poor sewage services meant that raw sewage was pumped onto the mountainside, increasing the saturation of the soils etc. One other factor we must consider is the amount and accessibility to modern technology, which aids in increasing the reaction time, ultimately leading to a lower death and damage rate. ...read more.
