Sharing Information/Thinking Ahead: In the Evaluate section of the worksheet, student pairs are asked to compose answers to two questionswhether they think seismology is a reliable science and ways seismic data is useful for engineers. 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.

As the drum rotated, the Every earthquake is recorded on numerous seismographs located in different directions. Collect any giveaways for the students, such as earthquake posters or plate tectonic fliers. In this investigation, participants will understand that S and P waves are used to find the epicenter of an earthquake by using seismograph data to triangulate an epicenter.

One seismogram indicates the distance to the epicenter. 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). 0 500 1000 1500 2000 2500 3000 Copyright USGS http://earthquake.usgs.gov/learn/kids/eqscience.php. What types of engineers might use this data the most? 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. m>r/Q[6 The lag time for any What is an earthquake? atrial depolarization. In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter. Earthquakes occur along faults, which are cracks in the Earths crust that build tension. Use this information to complete the following. The moment magnitude scale (MMS) was developed in the 1970s as a modification of the Richter scale and is better for measuring big earthquakes but less good for small ones. 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. 0000004060 00000 n

Activity 4: Locating an Earthquake Epicenter Examining Seismograms The three basic types of seismic wave generated by an earthquake at its focus are Pwaves, Swaves, and Surface waves. Share with Classes. (Grades
2. pen recorded the arrival of P, S, and surface Using 3 seismograms the students will be able to triangulate the epicenter of an earthquake. Last updated November 26, 2013. Use the process of triangulation to locate an earthquake's epicenter.
Add to Library. Looking at the nomogram, students click on each location data point to see where the three lines intersect to read the estimated magnitude. The Earthquakes Living Lab gives students the chance to track earthquakes across the planet and examine where, why and how they are occurring. Describe the process of triangulation to locate an epicenter. question 1 of 3. 0000003254 00000 n
This is determined by the P-and S-wave arrival times. After reading about earthquakes, open a new window to an Earthquake Simulator at, Follow the simulation instructions. Using this resource students find the arrival times of P-waves and S-waves using a seismogram. What data is used to determine magnitude? What is an earthquake? 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. 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. Divide the class into student pairs, and have them assemble at their computers with journals/paper and writing instruments. Richter scale Method of earthquake measurement based on the amplitude of seismic . Earthquakes can also cause tsunamis, which are very large waves that can damage coastlines and put coastal residents in danger. A little under 30 seconds, maybe around 26 seconds.

S waves. 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. The period of P waves is shorter, than the period of surface waves. Thus technology use varies from region to region and over time. Reading Strategy. 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. Since the 1970s, the use of the Richter magnitude scale has largely been replaced in the scientific community by the moment magnitude scale (MMS). 12), Analyze and interpret data about natural hazards using direct and indirect evidence
