PDF Page - 1 Lab 08 - Seismology - Locating the Epicenter of an Earthquake These distances are determined using a travel-time curve, which is a graph of Pand S-wave arrival times (see Figure 13.11). You will analyze the records and locate the earthquake using a method known miles from the epicenter of an Then do the same for the S-wave. P wave: The first seismic wave of an earthquake. 0000078100 00000 n How does distance from the epicenter affect the magnitude (height) of the seismograph reading? 0000002250 00000 n The arrival of seismic waves will be recognized by an increase in amplitude look for a pattern change as lines get taller and more closely spaced (ex. Millions of people witnessed the motion of the earthquake on television. 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. MS-ESS3-2. Before looking at the Earthquakes Living Lab, have pairs complete the, Then guide the teams to the Earthquakes Living Lab via the living lab website at. A seismograph is securely mounted onto the surface of the earth so that when the earth shakes, the entire unit shakes with it EXCEPT for the mass on the spring, which has inertia and remains in the same place. Success is figuring out that the epicenter is just off the coast of Chile, where the three circles intersect. This is determined by the P-and S-wave arrival times. P and Swaves are body waves and travel, through the interior of the earth. PDF Finding Epicenters Lab Answer Key Lab Pdf 74 Earthquake Activity: Locating the Epicenter and Time of Earthquake . What was the lag time (in minutes) at this location? Specifically, seismographs make recordings (seismograms) of the seismic waves generated from earthquakes, providing engineers and other researchers with data that they use to make predictions about future earthquakes. 0000106240 00000 n epicenter, the longer the lag time measured I also will take them through the general process of how find the difference in arrival times of p- and s-waves can be used to find a distance to an earthquake and how using data from 3 seismograph stations is used to locate the epicenter. Activity 4: Locating an Earthquake Epicenter, The three basic types of seismic wave generated by an earthquake at its focus are P, waves, Swaves, and Surface waves. The hypocenter is the point within the earth where an earthquake rupture starts. Earth and Space, Physical Science, A process called triangulation uses seismic data from three locations to identify the epicenter of an earthquake.copyrightCopyright USGS http://earthquake.usgs.gov/learn/kids/eqscience.php. 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. 0000005544 00000 n Explains how to find an earthquake epicenter using at least three seismograph stations. ?t?s=Yt '_( endstream endobj 76 0 obj <>stream pen recorded the arrival of P, S, and surface The farther a station is from the 0000006538 00000 n Reading Strategy. directly above it on the surface of the earth is called the epicenter. Describe what the "magnitude" of an earthquake is. velocity, amplitude, and frequency of the All the arcs should intersect at a common point - the epicenter. To locate the epicenter of the earthquake, seismologists use the . During an earthquake, seismic waves are sent all over the globe. waves from a distant earthquake. PDF. Alignment agreement: Hands-on Activity Earthquakes Living Lab: Finding Epicenters 15 Bill Nye - Earthquakes Worksheet Key Earthquakes occur when the big pieces of earth's crust, called plates, move a little. Civil engineers, who design houses, apartment buildings, schools, skyscrapers, bridges, highways, tunnels, water treatment facilities, factories and other structures, may use this data to help them create safer structures that are less likely to sustain damage during earthquakes. The vertical lines, spaced one, minute apart, represent the passage of time, (from left to right). CH 02 HW - Chapter 2 physics homework for Mastering, Leadership class , week 3 executive summary, I am doing my essay on the Ted Talk titaled How One Photo Captured a Humanitie Crisis https, School-Plan - School Plan of San Juan Integrated School, SEC-502-RS-Dispositions Self-Assessment Survey T3 (1), Techniques DE Separation ET Analyse EN Biochimi 1, Use a travel-time graph to convert lag time into distance. So the difference in the P- and S-wave arrival times determines the distance between the epicenter and a seismometer. However, please review it for the specific setting, materials, students, and conventional safety precautions. In order to determine the location of an earthquake epicenter, seismographs from at least three different places are needed for a particular event. 0000004457 00000 n at that station. The point where your ruler crosses the middle line on the chart marks the magnitude (strength) of the earthquake. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media. For example, After reading about earthquakes, open a new window to an Earthquake Simulator at, Follow the simulation instructions. Develop a solution to a technological problem that has the least negative environmental and social impact. 0000003966 00000 n EARTHQUAKES: Epicenter Determination and Seismic Waves First locate and mark the three seismic stations on the world map provided below. Fill Locating The Epicenter Of An Earthquake Worksheet Answers, Edit online. 0 500 1000 1500 2000 2500 3000 Resources. Since the 1970s, the use of the Richter magnitude scale has largely been replaced in the scientific community by the moment magnitude scale (MMS). Dochub is the best editor for changing your documents online. Legal. Finding the Epicenter. Make arrangements so that each student group has a computer with Internet access. Thus, the Richter scale is used for measuring small earthquakes (3.5 M or less), while the moment magnitude scale is used for measuring stronger earthquakes (3.5 M or higher). 0000001893 00000 n For lower grades, just introduce the concepts of triangulation and the magnitude scale; a thorough understanding of P and S waves is not vital. 0000001746 00000 n 2. Quick Tips. Section A - Operator Information 1. Record your answer from Lab Exercise #2, Step 1. How can you locate an earthquake's epicenter? Short for "primary wave" or "pressure wave." locating the epicenter of an earthquake activity - TeachersPayTeachers P and Swaves are body waves and travelthrough the interior of the earth. Even though the scale formulae are different, MMS retains the familiar continuum of magnitude values defined by the older scale. =Cv :~4yrXP 62{_,*Uq/O-oUNBr-$y~:G},#3e^CS6U*_zVGY7ZNUWk2f?? {%!,"{u5E&OOqA_"/uxn-kx+Vz*EQb)Q Last updated November 26, 2013. Click for facts and worksheets in PDF! 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. Doing this generates an S-P interval graph (time vs. distance, called the travel-time curve graph) from which they determine and select three epicentral distances.
