The Tectonic Activity andHazards option focuses on therange of natural hazardsgenerated by plate tectonics• In addition to understandingwhy these hazards happen,you will need to understand:• The impact of tectonicprocesses on the landscape• The impact of tectonic hazardson people• The ways in which peoplerespond to, and try to manage,natural hazards.Primary hazards SecondaryhazardsEarthquakes TsunamiLandslidesLiquefactionVolcanoes LaharsLandslidesTsunami I have to write a 70 mark essay for A level Geography and I don't get what the question asks or requires to answer it properly. My teacher only confused me further, any help is greatly appreciated! Question: Tectonic hazard profiles define the way in which people and governments respond to hazards. Discuss. Comparing the characteristics of earthquakes, volcanoes and tsunamis (magnitude, speed of onset and areal extent, duration, frequency and spatial predictability) through hazard profiles. Tectonic events can be compared using hazard profiles. These allow a better understanding of the nature of hazards, and therefore risks associated which each. What are the effects of tectonic hazards? There are two types of effects caused by tectonic hazards, these are primary and secondary effects. Primary effects are things that happen immediately as a result of a hazard. Secondary effects are things that happen in the hours, days and weeks after the initial hazard. Hazard profile -Compares the physical processes that all hazards share and helps decision makers to identify and rank the hazards that should be given the most attention and resources -One of the difficulties with hazard profiling, however, is the degree of reliability when comparing different event types. Tectonic hazards are hazard events caused by tectonic plates colliding into each other, moving against each other, moving apart or subduction between a less dense plate and a more dense plate. Examples of tectonic hazards include: Hazard Profiles What is a Hazard Profile? A description of the physical characteristics of a specific hazard and determination of its various descriptors including magnitude, duration, frequency, probability, and extent. Impacts of Groups of People Intro- when comparing different tectonic hazard events it can be seen that some can be seen have much larger costs than others, as well as they type of costs varying between different events for a variety of reasons. -One of the main reasons some tectonic hazards are more costly is the physical characteristics of the actual hazard event itself. The social and economic impacts of tectonic hazards (volcanic eruptions, earthquakes and tsunamis) on the people, economy and environment of contrasting locations in the developed, emerging and developing world. 1.5 Tectonic hazard profiles are important to an understanding of contrasting hazard impacts, vulnerability and resilience.
