P and S arrivals, you can now locate an earthquake your answers below. A circle with a radius of the distance to the quake can be drawn. 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 . Some places are more prone to earthquakes than others. See Answer. In order to determine the location of an earthquake epicenter, seismographsfrom at least three different places are needed for a particular event. Success is figuring out that the epicenter is just off the coast of Chile, where the three circles intersect. The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter. Mark the first arrival of the swave on each seismogram. HS]o01j6R0iMm4U=wL8]BE< Refer to the data table and use the difference in arrival times to determine the distance to the earthquake epicenter for Station 2. What was the lag time (in minutes) at this location? What data is used to determine magnitude? 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. What did it feel like? Use this information to complete the following. Place a ruler (or straight edge) on the chart between the points you marked for the distance to the epicenter and the amplitude. 0000001562 00000 n

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. THREE SEISMOGRAMS Seismogram A - New York, NY 1 minute 1. 1) Identify the general term for waves released from an earthquake. Draw your signature, type it, upload its image, or use your mobile device as a signature pad. In order to determine the location of an earthquake epicenter, seismographs from at least three different places are needed for a particular event. Divide the class into student pairs, and have them assemble at their computers with journals/paper and writing instruments. important in helping seismologists determine the epicenter of the earthquake. 500p;333aXb3

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. How are S and P waves used to determine how far away epicenters are? Show students some of the numerous online animations comparing the movements of P and S waves. 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. $8.25. EARTHQUAKES: Epicenter Determination and Seismic Waves First locate and mark the three seismic stations on the world map provided below. Do you agree with this alignment? It's a logarithmic scale from 1 to 10 with each succeeding level representing 10 times as much energy as the last. The farther a station is from the The distance to the earthquake epicenter is then determined using the "Earthquake P-Wave and S-Wave Travel Time" graph.

Practice with Triangulation: Locating an earthquake epicenter. 1. Activity: Locating an Earthquake Epicenter Lecture 3 Damage from the earthquake was widespread, but the actual location of the earthquake (the epicenter) Epicenter is the location on the surface of the Earth directly above where the earthquake starts. An earthquake is the violent movement of tectonic plates in the Earth's crust. directly above it on the surface of the earth is called the epicenter. The magnitude is the logarithm of the amplitude of the ground wave. Using 3 seismograms the students will be able to triangulate the epicenter of an earthquake. Reading Strategy. Review their answers to assess their base knowledge of the subject matter. surface wave? The real-world earthquake data is viewable via a graphical interface using a scaling map. 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.

2. 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. miles from the epicenter of an When an earthquake strikes, P waves arrive at a seismograph rst and S waves next. Assess their understanding based on the thoroughness of their answers. 4. The period of P waves is shorter, than the period of surface waves. Nov 2, 2020 Triangulation is used to determine the location of an earthquake.

Finding the Epicenter Determine the epicenter distance from three different seismographs. 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. This section explains what earthquakes and faults are and what causes earthquakes. In Figure 13.9, there is an example seismogram from a station that includes a minor earthquake.
