Hazards Natural Hazards and Risk: Where Earth processes and society intersect by Anne E. Egger, Ph.D. Reading Quiz Teach with this 1. Which data about natural hazards in a particular area are more helpful to scientists making predictions about future potentially hazardous events in that area? The frequency and magnitude of events in that area in the past. The global distribution of natural hazards. The tectonic setting of that area. The population density of that area and how it has changed. 2. All natural hazards put people at risk. true false 3. Anchorage, Alaska, and Los Angeles, California, are all cities that experience earthquakes, but the greater LA area has a much larger risk from earthquakes than Anchorage. Which of the following provides the best explanation for that difference? The greater LA area has more frequent and larger earthquakes than Anchorage. The greater LA area has a much larger population and more infrastructure. Anchorage is more prepared for earthquakes than Los Angeles. Los Angeles is on the coast and can also experience very large tsunamis. 4. Which of the following would be used to determine exposure to a given hazard in a particular area? The frequency and magnitude of hazardous events. Socioeconomic status of inhabitants of the area. The number of different potential hazards in the area. The number of people living in the highest hazard area. 5. Within communities, some groups are more vulnerable to the impact of hazards than others. Which factors increase the vulnerability of a community? Isolation and lack of communication within the community. Political power to implement building codes. Well-established and resilient infrastructure. More frequent hazardous events. 6. A hazardous event like a volcanic eruption becomes a disaster when __________. people are put at risk the hazardous event is very large a lot of people and buildings are exposed to the event the damage from the event overwhelms a community 7. The practice of continuously collecting data about a potential hazard is called __________. monitoring hazard mapping risk reduction adapting 8. If you were to want to learn more about your risk from major storms where you live, which of the following strategies would help you? Monitoring the weather for storms. Talking to your neighbors about what they have experienced. Finding out the frequency and magnitude of major storms in the past. All of the answers 9. If you were to seek out a place to live that had the lowest possible risk from earthquakes, which would be the most effective strategy? Look for a place with the strictest building codes for earthquake shaking. Look for a well-educated community that knows what to do in the event of an earthquake. Look for a place with the fewest, smallest earthquakes. Look for a small town with no tall buildings. Score Quiz
