Plate Boundaries Concept Sketch-INVESTIGATIONWhere Did This Earthquake Occur, and What Damage Might Be Expected?

INVESTIGATIONWhere Did This Earthquake Occur, and What Damage Might Be Expected?THIS COASTAL REGION CONTAINS TWO FAULTS, an active volcano, and several steep-sided mountains prone to landslides. Any of these features could cause ground shaking. You will use seismic records from a recent earthquake to determine which feature caused the observed shaking. From this information, you will decide what hazards this earthquake poses to each of the small towns in the area.11. Offshore is a coral reef that blocks larger waves, creating a quiet lagoon between the reef and the shore.• Examine the large illustration and read the text boxes describing the types of features that are present.• Use three seismograms to determine which feature is likely to have caused the earthquake.• Consider potential earthquake hazards to determine what dangers each small town would face from the earthquake.• Decide which town you think is the safest from earthquake-related hazards and justify your decision with supporting evidence.Goals of This Exercise:The area has several small towns and three seis-mometers, each named after the nearest town. Seismograms recorded at each seismic station during a recent earthquake are shown at the top of the next page. Use the available information to complete the following steps and enter your an-swers in the appropriate places on the worksheet or online. Procedures2. Along one part of the coastline, there is a thin, steep beach, called Roundstone Beach, that rises upward to some nearby small hills. The seafloor offshore is also fairly steep as it drops off toward the trench. 1. There is a deep ocean trench along the edge of the continent. Ocean drilling encountered fault-bounded slices of oceanic sedi-ment.3. The town of Sandpoint is built upon land that was reclaimed from the sea by piling up loose rocks and beach sand until the area was above sea level. A. Observe the features shown on the three-dimensional perspective. Read the text associated with each location, and think about what each statement implies about earthquake hazards.B. Inspect the seismograms for the three seismic stations to determine where the earthquake probably occurred. You can get an idea from simply comparing the time intervals between the arrivals of P-waves and S-waves for each station.C. Use the graph next to the seismograms to determine the distance from each station to the epicenter. This will allow you to more precisely locate the epicenter. Detailed instructions for this procedure are listed in topic 7.7 earlier in this chapter. For plotting your results, a map view of the area is included on the next page and a larger version is on the worksheet.D. From the general location of the earthquake, infer which geologic feature is likely to have caused the earthquake.E. Use the information about the topographic and geologic features of the landscape to interpret what types of hazards the recent earthquake posed for each town. From these considerations, decide which three towns are the least safe and which two are the safest for this type of earthquake. There is not necessarily one right answer, so explain and justify your logic on the worksheet, if asked to do so by your
