Lab Lesson 4 - Lab Lesson 4: Earthquakes and Seismology, The vertical lines, spaced one, minute apart, represent the passage of time, (from left to right). travel 3,000 miles. Multiply the difference by 8.4 to estimate the distance, in kilometers, from the seismograph station to the epicenter. Make an overhead copy of each of the handouts. Mark the first arrival of the swave on each seismogram. 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.

Facility Name Busine Child ren Information Child Name C. Child Social Security Number Type of Case being filed - Check only one category. Using online resources and simulations available through the Earthquakes Living Lab, students explore the consequences of subsurface ground type and building height on seismic d Seismographs are measuring devices designed by engineers and used by researchers to determine the locations and magnitudes of earthquakes. In the U.S., earthquake measurements under the MMS (those of magnitude 3.5 or higher) are still commonly erroneously referred to by the general public and media as being on the Richter scale, due to more familiarity with the Richter scale. earthquakes. Every year, earthquakes cause death and destruction worldwide. HtA1D41`s(GME$Ke*YdEOYf2-:r. directly above it on the surface of the earth is called the epicenter. The answer is the San Andreas Fault. 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. How does the period of the P waves compare to the period of the surface waves? Edit your locating an earthquake epicenter worksheet answers online. Where the 3 circles intersect is the approximate location to the epicenter of the earthquake. 0000002507 00000 n 5 4. Pwaves have the greatest velocity and reach the, seismic station first. In this activity, the epicenter of the earthquake is in the center of Los Angeles, CA. minutes? Draw your signature, type it, upload its image, or use your mobile device as a signature pad. Then do the same for the S-wave. 9 - Add to FlexBook Textbook. Learn more How Can I Locate the Earthquake Epicenter? Epicenter Location on Earth's surface directly above the focus of the earthquake 5. Direct students to finish the activity by completing the. If a quake is far from the seismograph, the P-waves arrive long before the S-waves. If a quake is near the seismograph, the S-waves arrive shortly after the P-waves. DOC Home - Westerville City Schools Once three seismographs have been located, find the time interval between the arrival of the P-wave . ya{I;W@DgMN2:UtbT=*+cY1.8Vm(u3Zt"J @9TAjJH@H_F3n7\Srdw~gAR#JQGj`ueS! 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. 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. %PDF-1.4 % HS]o01j6R0iMm4U=wL8]BE< 100 km 4.1 km/s 24.4 s; Finding the epicenter (continued) data table analyze and conclude answer the following questions on a separate sheet of paper. Lab Activity Locating Epicenters Flashcards | Quizlet Even though the scale formulae are different, MMS retains the familiar continuum of magnitude values defined by the older scale. Most of these earthquakes are small tremors that cant be felt by people, but occasionally an earthquake occurs on a large magnitude that causes millions of dollars in property damage and kills hundreds to thousands of people.
