Natural Disasters Fall 2022 Joshua Fernandez 1 What are some reasons people live in geologically dangerous areas Reasons why people live in geologically dangerous areas is due to multiple reasons such as economic purpose and frivolous reasons The land is inexpensive having large land for agriculture economic and because of the scenic environment frivolous 2 Is the geological landscape controlled by gradual and unrelenting processes or intermittent large events with little action in between Provide an example to illustrate Although gradual processes have an effect on landscape it is generally caused by large events An example would be a stream As when there is little to no rain the stream is fine but when there is a heavy storm which causes flooding the stream would erode the channels 3 Some natural disasters happen when the equilibrium of a system is disrupted What are some examples An example would be a landslide caused by heavy rain or an earthquake 4 Contrast the general nature of catastrophic losses in developed countries versus poor countries Natural disasters tend to damage more property and kill more people in poor countries compared to developed countries because developed countries tend to have better safety measures and resources Also developed countries lose a lot of property due to damage while developing countries tend to lose more lives 5 What are the main reasons for the ever increasing costs of catastrophic events The main reasons for increasing costs are because of the resources that need to be financed in developed countries This would include the warning systems evacuation plans disaster relief plans and construction of destroyed buildings Compared to developing poor countries they tend to have poor disaster relief plans warning systems and so on 6 If people should not live in especially dangerous areas what beneficial use is there for those areas The beneficial use for that area would be to become public areas like a park not entirely sure 7 When is a large event such as a major earthquake not a disaster A large event like an earthquake is not a disaster when it happens in a remote area or if it does not affect anyone 8 When an insurance company decides on the cost of an insurance policy for a natural hazard what are the two main deciding factors The two main deciding factors are the probability of an event and money loss after the event 9 Describe the general relationship between the frequency and magnitude of an event Natural Disasters Fall 2022 Joshua Fernandez The general relationship between frequency and magnitude is inversely proportional Giant events are more powerful and infrequent compared to smaller events that could happen frequently 10 When people or governmental agencies try to restrict or control the activities of nature what is the general result The general result of nature trying to be controlled would be transferring the problem to someone else or delaying it for another time 11 What kind of information must be assembled to make hazard predictions Information needed to make predictions would include historical data and information like occurrences and how powerful severe the even was 12 What is a precursor event A precursor event is an event that happens before a giant event It is almost like a warning of what is to come An example would be a tsunami Before a major tsunami the precursor event would be tectonic plate movement which causes an earthquake which then causes a tsunami 13 Explain how population growth increases the number of disasters Population growth increases the number of disasters because of where people are located If there is a region with a dense population more disasters will happen as there are more people and buildings which could cause more damage 14 What are the stages of disaster recovery The stages of disaster recovery would be the emergency phase followed by the restoration phase then ends with the reconstruction phase 15 Provide 3 methods of hazard mitigation Three methods of hazard mitigation would include engineering solution which is modifying the natural environment to try and control nature Hazard warning systems and evacuation procedures like the EAS which is a national system in the US for state and local emergencies Land use planning which is the abandonment and restrictive zoning of hazardous areas
