Activity: Locating Epicenters
PROCEDURE A:
Use the three seismograms from "Seismograms A" to calculate the following for each city and fill it into
the chart below:
1. The arrival time for the P and S wave.
SP 2. The difference in the arrival time between P and S-waves.
ESRT 3. The distance (in km) of the epicenter from each city. WEDGE method
4. The length of time it took for the P-wave to travel from the epicenter to each city.
5. Calculate the time at which the P-wave started.
6. Locate the epicenter on "Map A" by constructing a circle whose radius is equal to the distance
from the city to the epicenter for all three cities.
7. Where all three circles meet, draw an arrow and label it "epicenter".
