Natural Hazards Natural Hazards are comprised of 2 parts: 1. A natural disaster (a physical event e.g. volcanic eruption, earthquake, landslide). 2. Human activity – for example coastal settlement of populations Basically….. A natural disaster is an event that has an effect on people resulting from the natural processes in the environment. Vulnerability Vulnerability is the susceptibility to physical or emotional injury or attack Human vulnerability leads to financial, structural, and human losses. A natural hazard will therefore never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas. The risk of natural disasters is increasing as a result of population growth, urbanization, and alteration of the natural environment. Positive Effects Events that societies label as natural ''disasters" may also have beneficial ecological consequences. However, these benefits tend to only manifest themselves months or years after an extreme event (e.g., rejuvenation of a coniferous forest months and/or years after fires), or are often not readily apparent (e.g., recharging of groundwater stocks after a flood). Assignment Create your own powerpoint presentation about a natural hazard. You will be assigned a particular hazard. You will work in groups of 4. You will have 2 periods to complete this assignment. Should be 6-8 slides This will not be presented to the class, instead put it into Miss Wilkins pass in folder when you are finished. Criteria 1. Describe what the natural hazard actually is. 2. Describe the causes 3. Describe the effects on humans 4. Describe the positive/negative effects on ecosystems 5. Provide ways that we can reduce the effects The project will be marked out of 10. 2 points will be awarded for including each of the 5 criteria.
