Construct an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem. How does distance from the epicenter affect the S-P time interval? Entering the three maximum amplitudes generates a nomogram, a graphical device that simplifies the process of estimating magnitude from distance (determined earlier in the tutorial from the S-P interval process) and amplitude.

They make a model of a seismographa measuring device that records an earthquake on a seismogram. to the lag time measured at this location? minute apart, represent the passage of time Epicenter Location on Earth's surface directly above the focus of the earthquake 5. As you may know, people have look numerous times for . Use the graph to answer the questions that follow. Draw your signature, type it, upload its image, or use your mobile device as a signature pad. HS-PS4-1. P wave. Scientists and engineers around the globe gather data through observation and experimentation and use it to describe and understand how the world works. $8.25. !5(~q* The period of a wave is the time between two adjacent wave peaks. What about P waves? 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. seismogram. 0000006011 00000 n 0000009174 00000 n How is the magnitude of an earthquake determined? 74 Earthquake Activity: Locating the Epicenter and Time of Earthquake .

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. Practice with Triangulation: Locating an earthquake epicenter. One seismogram indicates the distance to the epicenter.
