Describes the fault orientation and slip direction of an earthquake and are generated using first motion (up or down) observations.Solution 1
Number of P First motions: 19
| Plane A | Plane B | Uncertainty | |
|---|---|---|---|
| Strike | 280 | 10 | 33 |
| Dip | 90 | 10 | 3 |
| Rake | 100 | 0 | 60 |
Discrepant Stations
Stations whose observed first-motion does not match the predicted first-motion from the focal mechanism.| Station | Network | Channel | Polarity | Quality |
