Answer:
Geologists appropriate seismic streams to determine an earthquake's epicenter.
Step-by-step explanation:
You first require to record the coming times of the P waves and S waves from the seismograph and then deduct them.
Once you discover the time variation, you then require to look on a distance-time plan to discover how far from the epicenter that 1 seismograph is.
Then, on your map, using the map's scale, you need a compass and initiate the compass just to the distance you determined on the distance-time graph.
Using the area of the seismograph as the center-point, trace around with the compass. The range of your circle should be equivalent to the measure from the distance-time graph.
You later need to do this alike calculation for two additional seismographs. Where the three circles meet, such is the epicenter of that earthquake.
