A circle is drawn from each of the three different seismograph locations, where the radius of each circle is equal to the distance from that station to the epicenter. P wave. The point where your ruler crosses the middle line on the chart marks the magnitude (strength) of the earthquake. Click for facts and worksheets in PDF!

Lab 8 - earthquake lab - Lab: Locating the Epicenters of Earthquakes Thanks for your feedback! triangulation: A method to determine exactly where an earthquake originates. 100 km 4.1 km/s 24.4 s; Finding the epicenter (continued) data table analyze and conclude answer the following questions on a separate sheet of paper. Video Guide / Worksheets and Quizzes for Quizzes and Answer Sheet __ 2. Explains how to find an earthquake epicenter using at least three seismograph stations. In this activity, students use an online simulationVirtual Earthquakethat is accessible through the Earthquakes Living Lab interface, to locate the epicenter of an earthquake by making simple measurement on three seismograms, recordings of an earthquake's seismic waves detected by instruments (seismographs) far away from the earthquake. They make a model of a seismographa measuring device that records an earthquake on a seismogram. 0000003254 00000 n
The epicenter of an earthquake can be found using the difference between the arrival of the Primary and Secondary waves. Do you agree with this alignment? Thus technology use varies from region to region and over time. m>r/Q[6 9 -
Locating Earthquake Epicenter Teaching Resources | TPT Use of the TeachEngineering digital library and this website constitutes acceptance of our Terms of Use and Privacy Policy. The western U.S. has more faults than the eastern U.S., and therefore the western U.S. has more earthquakes. The spot where those three circles intersect is the epicenter (Figure 13.12).

Hand out the worksheets to the groups and direct them to read through the instructions. Copyright USGS http://earthquake.usgs.gov/learn/kids/eqscience.php. (5 minutes) Discuss how gathering information on epicenters can be applied. important in helping seismologists determine the epicenter of the earthquake. hbbd``b`$C`q9 X_$_g`bdxc`X locating the epicenter of an earthquake activity - TeachersPayTeachers 0000003991 00000 n
How are S and P waves used to determine how far away epicenters are? 0000030504 00000 n
The period of P waves is shorter, than the period of surface waves. Short for "primary wave" or "pressure wave." Point on Earth's surface directly above an earthquake's focus. Mapping the history of natural hazards in a region, combined with an understanding of related geologic forces can help forecast the locations and likelihoods of future events. Seismic stations detect earthquakes by the tracings made on seismographs. ACTIVITY 4.2B Locating an Earthquake Figure 4.5 shows seismograms for the same earthquake recorded at three locations - New York, Nome, Alaska, and Mexico City. (Source: USGS, Wikipedia). 2. This activity is designed around the Earthquakes Living Lab, a resource and online interface that uses real-time U.S. Geological Survey seismic data from around the world. Have students click on the Earthquakes Living Lab hyperlink in the top left in the earthquakes section. by. Students also investigate which structural designs are most likely to survive an earthquake. Contact the teacher to find out the length of the class period, as well as how many copies of handouts and sets of materials you need to bring. and S waves depends on the distance from the epicenter of the answer the following question. Every earthquake is recorded on numerous seismographs located in different directions. Y$Kr;V6[;Dq vg~cx:A[^jCssupwD

Scientists and engineers around the globe gather data through observation and experimentation and use it to describe and understand how the world works. So next, students compute the magnitude of this same earthquake by looking at the three simplified seismograms again, but this time selecting each's maximum S wave amplitude (height). Take a few minutes to read the information on the left side of this page for the 2010 earthquake off the coast of central Chile. Figure 2. 0000003966 00000 n
PDF Locating An Earthquake Epicenter Lab Answers - Full PDF U.S. Geological Survey, U.S. Department of the Interior. Why might the triangulation method not always produce an exact point (other than your measurement errors)? After reading about earthquakes, open a new window to an Earthquake Simulator at, Follow the simulation instructions. If a quake is near the seismograph, the S-waves arrive shortly after the P-waves. The three seismograms in this activity are unfi ltered station records from a single event that occurred on August 1, 1999. Some places are more prone to earthquakes than others. Thanks for your feedback! Solved Lab Exercise #2: Locating the Epicenter of an - Chegg 0000002250 00000 n
Triangulation is required to determine exactly where it happened. First, determine the P-wave arrival, and read down to the bottom of the seismogram to note at what time (usually marked in seconds) that the P-wave arrived.
