Lab 4-5 Epicenter Location Analysis and Answer Key

To pinpoint the location of seismic activity, it’s important to understand the method of triangulating the origin of an earthquake. By analyzing data from multiple monitoring stations, you can calculate the distance from each station to the event’s origin and then use that information to determine the coordinates of the epicenter.

Start by examining the seismic waves recorded at each station. The P-wave travels faster than the S-wave, so the difference in arrival times allows for the calculation of the distance from the event. With this data, you can draw circles around each station. The point where all circles intersect represents the earthquake’s epicenter.

To solve the exercises accurately, remember to pay attention to the timing differences between the seismic waves at each station. Accurate calculations are critical for pinpointing the correct location. By practicing these steps, you can master the technique of locating seismic origins based on real-world data.
