To abbreviate, use the symbol M (a capital M, plain text, no sub/superscripts) expressed to the nearest 0.1. They use three seismographs in a process called triangulation to determine earthquake epicenters. Using the real-world data in the living lab enables students and teachers to practice analyzing data to solve problems and answer questions, in much the same way that scientists and engineers do every day. Even though the scale formulae are different, MMS retains the familiar continuum of magnitude values defined by the older scale. approximate period of the surface waves in seconds?

Question 5 of 22 4.55/ 4.55 Points Questions 5 through 11 are based on Lab Exercise #2: Locating the Epicenter of an Earthquake. In order to determine the location of an earthquake epicenter, seismographsfrom at least three different places are needed for a particular event. How does distance from the epicenter affect the S-P time interval? Construct an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem.

Today we will be using a traveltime graph, where the vertical separation between, the P and S curves is equal to the difference in the arrival times between the Pwave, and Swave. The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing. A little under 30 seconds, maybe around 26 seconds. Notify the classroom teacher of technology needs (overhead projector). velocity, amplitude, and frequency of the Draw your signature, type it, upload its image, or use your mobile device as a signature pad. surface wave?

Note the differences in The travel-time graph Get the inside scoop on all things TeachEngineering such as new site features, curriculum updates, video releases, and more by signing up for our newsletter! minutes = 6 minutes. All the arcs should intersect at a common point - the epicenter. 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. 0000001893 00000 n
Choose an answer and hit 'next'. Legal. In Figure 13.9, there is an example seismogram from a station that includes a minor earthquake. Dochub is the best editor for changing your documents online. Focus (aka Hypocenter) is the location in the Earth where the earthquake starts. The time The earthquake occurred somewhere along that circle. 74 Earthquake Activity: Locating the Epicenter and Time of Earthquake . This is determined by the P-and S-wave arrival times. Sixty-seven people lost their lives, and property damage was estimated at $6 billion. In a concluding class discussion, have groups share their ideas about engineering and one new thing they learned about earthquakes. In this 1-to-10 logarithmic scale, each succeeding level representing 10 times as much energy as the last. Lab Exercise #2: Locating the Epicenter of an Earthquake In this lab exercise, you will locate the epicenter of an earthquake. The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. To locate the epicenter of the earthquake, seismologists use the . longer or shorter). S waves. 2. Considered best for measuring small earthquakes (3.5 M or less). travel time for P waves. If the lag time were measured at a location closer to the epicenter, how would it compare Great-circle arcs are drawn on the globe using the distance of the earthquake to the station as a radius. HTn0MmcHCB How does the lag time change as you get farther and 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. EARTHQUAKES: Epicenter Determination and Seismic Waves First locate and mark the three seismic stations on the world map provided below. Focal Depth. After this activity, students should be able to: Each TeachEngineering lesson or activity is correlated to one or more K-12 science,

The simulation renders three circles on a map and directs students to find the epicenter. 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. 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. Was there an initial quake followed by smaller quakes? Students learn about the types of seismic waves produced by earthquakes and how they move through the Earth.

Before going to the classroom, you will need to: Provide each student, with the following: Earthquakes occur every day all over the United States and all over the world. HtA1D41`s(GME$Ke*YdEOYf2-:r. 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. If your seismograph station is Assess their understanding based on the thoroughness of their answers. 9 -
It is called triangulation because a triangle has three sides, and it takes three seismographs to locate an earthquake. Using historical seismographs, engineers forecast the strength or magnitude of earthquakes and make predictions and determine building codes and safety protocols. Figure 1 is a simplified example of a Make changes to the sample. A. Seismic waves-waves generated by an earthquake, can move the ground forward and back- answers the question. activity 4 locating an earthquake epicenter The Science of Earthquakes | U.S. Geological Survey An earthquake is what happens when two blocks of the earth suddenly slip past one .

Develop a solution to a technological problem that has the least negative environmental and social impact. The period of a wave is the time between two adjacent wave peaks. important in helping seismologists determine the epicenter of the earthquake. Mr Gneiss. If the lag time were measured at a location closer to the epicenter, The period of a wave is the time between two adj, How does the period of the P waves compare to t. Use data from seismograms to locate the epicenters of earthquakes. To make a magnitude determination, two measurements are needed: the S-P interval (already determined earlier in the tutorial) and the maximum amplitude of the seismic waves.
