Name Lauren Attardi Learning Unit 1 Introduction to Natural Disasters Review Questions This assignment is designed to assess your understanding of Unit 1 and includes some of the Questions for Review at the end of Chapter 1 from your text plus a few additional questions Each question can be answered in one to two sentences Please limit yourself to a maximum of three sentences Access the assignment complete it with ANSWERS IN A DIFFERENT COLOR FONT and save as a separate file and send it back for evaluation and grading through the assign ment tab by or before the due date 1 What are some reasons people live in geologically dangerous areas Some reasons for people choosing to live in geographically dangerous areas would be to be closer to natural water sources better farm land and soil and other benefits that these areas can bring Living down hill from a water source is beneficial for fresh water but add the threat of flooding and vas open areas are great for farming but also bring on tornados as a possibility 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 The geologic landscape is controlled by intermittent large events which means some processes operate slowly gradually ex shifting of the continents and tectonic plates and less common catastrophic events have sudden major impacts ex tsunamis volcanic eruptions 3 Contrast the general nature of catastrophic losses in developed countries versus poor countries Developed countries will face loss in corporations buildings investments and money in catastropich events while poor countries lose lives 4 What are the main reasons for the ever increasing costs of catastrophic events The cost of catastrophic events is ever increasing due to the population rising and thus more hazardous areas are being used in high volumes due to migration 5 If people should not live in especially dangerous areas what beneficial use is there for those areas Those dangerous areas can be beneficial for use as public places Such as natural preserves for visiting and tourists parks and even golf courses Something less in use and population that communities 6 When is a large event such as a major earthquake not a disaster According to our textbook a natural disaster is defined as a natural event that adversely affects people property thus if a natural event occurs in a separate are away from cities and people live an open space of land and no damage is done it is not considered a natural disaster 7 When an insurance company decides on the cost of an insurance policy for a natural hazard what are the two main deciding factors An insurance company would consider to likelihood of the natural hazard occurring based on geophraphy of the area and research With that considered they would then look at the probably damage the hazard could inflict 8 Describe the general relationship between the frequency and magnitude of an event The relationship could be described as always related and never not This means they are inversely related Numeral small hazards and only a few large hazards would be similar in damage and the damage caused is what would say the magnitude When people or governmental agencies try to restrict or control the activities of nature what is the general result 9 The general result is usual the same that the event is only made an issue somewhere else or only pushed back and avoided for a period of time Natural events cannot be avoided too often as we lack any control 10 What kind of information must be assembled to make hazard predictions Research on the past that can help predict what the past damage from said event were and how severe they event was This is referred to as historical data 11 What is a precursor event A precursor event is an event or multiple events that come before a natural event which may warn of coming disaster 12 Explain how population growth increases the number of disasters Similar to why natural disasters keep increasing in cost to rebuild the same explanation can be used to explain why the number of distastes increase in general The more people on the planet the more land we need to use to settle in communities and towns The higher the population the more land even potentially dangerous land will need to be used 13 What are the stages of disaster recovery There are 3 stages of distaste recovery emergency work restoration of services communication lines reconstruction These stages help organize what must be done immediately to help recover and what can come later as time passes 14 Provide 3 methods of hazard mitigation Hazard mitigation is described as steps that can be taken to help prepare for natural disasters 3 methods include planning ahead land use to avoid using too much and triggering a disaster taking extra mind is risk assessment of land and use of natural resources and engineering solutions thinking ahead for ways to solve any damage done
