| Locating Center of Earthquake |
|
Definition
| 1. Use seismometer to measure the difference in P- and S-wave arrival times. 2. Use known velocities of these waves to calculate the distance of epicenter from seismometer. 3. Use distance calculations from three stations to triangulate the exact position of the earthquake epicenter. |
