AIM: How do we find the epicenter of an earthquake? OBJ: Given notes and lab SWBAT determine the location of the epicenter of an earthquake using their.
College Style Report - use iPad/Phone camera Procedure : 1) You can find the distance to the epicenter for a given location by plotting “the difference between P/S wave arrival times” on the gridded (P/S Wave) Chart. Enter this data on the data table. 2) Repeat step 1 for the remaining locations. 3) For each location, set the drawing compass equal to the distance to the epicenter for that location. Then, locate the seismic station on the map and draw the circle. 4) Repeat step 3 for remaining locations. Where all three circles intersect is the epicenter of the earthquake.

Title: Finding The Epicenter (FTE) LabProblem: How Do We Find An Earthquake’s Epicenter?Hypothesis: Given1)the difference between P/S-wave arrival times, 2)geographic map (with the 3 seismic stations) and 3)P/S Wave Chart,
the earthquake’s epicenter can be found.Materials: P/S Wave Chart, Geographic Map, drawing compass, pencil, seismic data
College Style Report - use iPad/Phone cameraProcedure: 1) You can find the distance to the epicenter for a given location by plotting “the difference between P/S wave arrival times” on the gridded (P/S Wave) Chart. Enter this data on the data table.2) Repeat step 1 for the remaining locations.3) For each location, set the drawing compass equal to the distance to the epicenter for that location. Then, locate the seismic station on the map and draw the circle.4) Repeat step 3 for remaining locations. Where all three circles intersect is the epicenter of the earthquake.
Abstract “science concepts”1) if the difference between P/S Wave
arrival times is small, the epicenter is close but
2) if the difference between P/S wave arrival times is large, the epicenter is farther away.
3) Need at least 3 seismic stations to find an earthquakes epicenter
At Least 3 Seismic Stations

5 station = 1epicenters
1 station =numerousepicenters
