Distance to the Hypocenter
The distance to the hypocenter is calculated based on the difference in the velocities of the P wave and the S wave. (Omori formula)
| Distance to the Hypocenter d | km |
- Calculation Formula
- The first wave (Primary Wave) is the P wave, and the next wave (Secondary Wave) is the S wave.
- The Omori constant k varies depending on location and earthquake depth.
