Question.5125 - Module 8 Discussion: Earthquakes in your backyardAssignment objective:Students will examine maps showing the faults running through the Bay Area and identify the fault nearest themStudents will assess the risk of a major earthquake happening on a fault near them in the next 25 years as well as the seismic hazard where they liveStudents will examine the history of past earthquakes on the faults nearest them and post their thoughts about seismic hazard to the class discussionConnection to module objectives:Discuss and assess the various hazards associated with earthquakesIdentify the major faults in the Bay Area fault zone, including the fault nearest to where you liveDescription:We live in one of the most active earthquake zones on our planet! No less than 6 major faults run through the Bay Area. In this assignment, I want you to research the earthquake hazard where you live and report it to the class. Include this information in your post:Use this interactive map of major Bay Area faultsLinks to an external site., created by the US Geological Survey, to identify which fault is closest to where you live. You can scroll around to where you live, or just put in your address in the search bar and then zoom out until you see the nearest major fault (shown in color, not a black dashed line). You can use this mapLinks to an external site. to figure out which fault it is, or you can just click on the fault in the interactive map and look under "fault name" in the little info box that pops up. Also include in your post how long this fault is. Info to include from this item:Name of the major fault nearest you, and how long that fault is.This map shows the major Bay Area faults Download This map shows the major Bay Area faultsand the probability of a magnitude 6.7 or greater earthquake happening on each of them before 2043. What is the probability of the closest fault to where you live having an earthquake that big in the next 20 years? Info to include from this item:Probability of a magnitude 6.7 or greater earthquake happening on the fault closest to where you live in the next 20 yearsLiquefaction is a major component of the seismic hazard that depends a lot on where a structure is built. Liquefaction risk is highest where structures are built on unconsolidated sediments as opposed to rock or sediments that are well on their way to becoming rock. Use this liquefaction risk mapActions produced by the California Geological Survey to determine the liquefaction risk where you live. You may have to zoom in and use Google Maps or some other tool to figure out where exactly on this (static) map you live. Info to include from this item:The liquefaction risk where you live.When did the last major earthquake occur on the fault closest to where you live? Use this history of Bay Area earthquakesLinks to an external site. going back to 1838 to determine the following about the nearest major fault to where you live:When did the most recent major earthquake occur on this fault? If we don't know, choose the next closest fault instead, until you find a Bay Area fault with a recorded earthquake since 1838What was the magnitude of this earthquake?By now, you are likely significantly better informed about earthquakes, faults, and seismic hazard in the Bay Area than the vast majority of its residents. Congratulations on being informed citizens! Given what you know, how do you feel about earthquake hazard where you live? Are you more worried or less worried than you were before? Write a paragraph on your experience going through this earthquake module that includes the following:What are three things you learned that you didn't know before? What stood out to you the most or was the most interesting or useful to you?How do you feel about earthquake hazard having just done this module?Last, but certainly not least, leave a thoughtful, constructive comment on a classmate's post on this discussion board. We learn best when we learn from and support each other as a community of learnersSteps:Post a reply to this discussion with the following information:Name of the major fault nearest you, and how long that fault is.Probability of a magnitude 6.7 or greater earthquake happening on the fault closest to where you live in the next 20 yearsThe liquefaction risk where you live.When did the most recent major earthquake occur on this fault?
