[k0 |`2dGXGGGd00A(60P-e = F5n -f$ C As discussed earlier in this lesson, this method of determining the epicenter of an . inch = 500 km. Do you agree with this alignment? In order to determine the location of an earthquake epicenter, seismographsfrom at least three different places are needed for a particular event. It takes S waves 14. Once three seismographs have been located, find the time interval between the arrival of the P-wave and the arrival of the S-wave. Material is sheared side to side, perpendicular to the direction of wave propagation. 0000001675 00000 n
EARTHQUAKES: Epicenter Determination and Seismic Waves First locate and mark the three seismic stations on the world map provided below. An earthquake is what happens when two blocks of the earth suddenly slip past one directly above it on the surface of the earth is called the epicenter. Why might the triangulation method not always produce an exact point (other than your measurement errors)? This section explains what earthquakes and faults are and what causes earthquakes. These natural disasters may be mitigated, however, by insightful and creative engineering. (from left to right). 0000001978 00000 n

As the drum rotated, t, pen recorded the arrival of P, S, and surface, between arrival of P and S waves is called, epicenter, the longer the lag time measured, velocity, amplitude, and frequency of the. The farther a station is from the The real-world earthquake data is viewable via a graphical interface using a scaling map. While earthquake locations are normally done with a computer that can quickly determine the paths of seismic waves through the Earth to many seismic stations, 15 Introduction to Geology Chapter Worksheet . This is determined by the P-and S-wave arrival times. 17 Station St., Ste 3 Brookline, MA 02445. You will receive your score and answers at the end.

consider a seismograph stationed 3, Geologists use seismic waves to locate an earthquake's epicenter. 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. Find 23 millimeters on the right side of the chart and mark that point. 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. Legal. (Grades
Earthquake Location 2 Using the skills that you acquired in the picking P and S arrivals, you can now locate an earthquake using real seismic records. Success is figuring out that the estimated magnitude is 5.9. Divide the class into student pairs, and have them assemble at their computers with journals/paper and writing instruments. Direct student pairs to independently complete the tutorial/simulation to find an epicenter location via the triangulation method and compute the earthquake magnitude: The simulation directs students to look at three simplified seismograms from seismic stations in Chile (Talca, Santiago, Osorno) and select the correct measurements of the S-P intervals. Edit your locating an earthquake epicenter worksheet answers online. 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. 0000003991 00000 n
