In Figure 13.9, there is an example seismogram from a station that includes a minor earthquake. at that station. Epicenter Location on Earth's surface directly above the focus of the earthquake 5. The answer is the San Andreas Fault. How might they use this information? Alignment agreement: Success is figuring out that the estimated magnitude is 5.9. In this activity, the epicenter of the earthquake is in the center of Los Angeles, CA. The seismometers are shown as green dots. This is determined by the P-and S-wave arrival times. Scientists and engineers around the globe gather data through observation and experimentation and use it to describe and understand how the world works.

Make an overhead copy of each of the handouts. Many updates and improvements! There are two sets of data and maps to do this activity/ lab for than once. Introduction: Before student pairs look at the Earthquakes Living Lab, direct them to complete the Engage section of the Finding Epicenters and Measuring Magnitudes Worksheet, which asks them to apply any prior knowledge and/or speculate as to what the Richter magnitude scale is and what an epicenter is. minutes and P waves 8 minutes to Figure 8. consider a seismograph stationed 3, 15 Bill Nye - Earthquakes Worksheet Key Earthquakes occur when the big pieces of earth's crust, called plates, move a little. Though they may weaken with distance, seismographs are sensitive enough to still detect these waves. Conclude the activity with a class discussion (and perhaps homework questions) to share ideas and answers, as described in the Assessment section. Using 3 seismograms the students will be able to triangulate the epicenter of an earthquake.

In order to determine the location of an earthquake epicenter, seismographs from at least three different places are needed for a particular event. The, amount of time that passes between the Pwave arrival and the Swave arrival is. Assess their understanding based on the thoroughness of their answers. 0000078100 00000 n between arrival of P and S waves is called Details. 0000001777 00000 n The point where your ruler crosses the middle line on the chart marks the magnitude (strength) of the earthquake. Sixty-seven people lost their lives, and property damage was estimated at $6 billion. Question: ACTIVITY 2B Locating an Earthquake Figure 5 shows seismograms for the same earthquake recorded at three locations-New York; Nome, Alaska; and Mexico City. One seismogram indicates the distance to the epicenter. 0000053998 00000 n Describe the process of triangulation to locate an epicenter. The magnitude is the logarithm of the amplitude of the ground wave. If you draw a circle on a map around three different seismographs where the radius of each is the distance from that station to the earthquake, the intersection of those three circles is the epicenter. The western U.S. has more faults than the eastern U.S., and therefore the western U.S. has more earthquakes. Key Facts & Information. Have students click on the Earthquakes Living Lab hyperlink in the top left in the earthquakes section. 0000033429 00000 n Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings. Focus (aka Hypocenter) is the location in the Earth where the earthquake starts. This is determined by the P-and S-wave arrival times. Figure 1 is a simplified example of a Moment magnitude scale. How do we determine the epicenter of an earthquake? Have students turn in their answers for the Explain portion of the worksheet. Every year, earthquakes cause death and destruction worldwide. minutes = 6 minutes. How is the magnitude of an earthquake determined? 12 Earthquake Location Lab Answer Key Full PDF - www.yvc.moeys.gov The instrument detects and documents the intensity, direction and duration of ground vibrations, which are used to determine the epicenters and strength/magnitudes of earthquakes or other seismic events. Once three seismographs have been located, find the time interval between the arrival of the P-wave and the arrival of the S-wave.
