| 21. | Kanamori invented the method for calculating slip distribution on the fault plane by teleseismic waveform with Masayuki Kikuchi.
|
| 22. | However, there are still disputes over whether the fault plane should have been in the NW or the NE direction.
|
| 23. | Thus, with the same method, small scale earthquakes are also used to identify fault planes in the Tj�rnes Fracture Zone.
|
| 24. | Stacking velocity measurements and sonic logging in the area helped to determine that the fault plane slopes at 25 30?
|
| 25. | This allows for motion along the fault plane to be estimated and its location in the earth s subsurface mapped.
|
| 26. | The offset of sand and shale beds occurring along fault planes bring sand and shale layers in contact to each other.
|
| 27. | A " fault trace " or " fault line " is the intersection of a fault plane with the ground surface.
|
| 28. | The 1989 event's oblique-slip rupture was at 10 km and below on a fault plane that dipped 70?to the southwest.
|
| 29. | The areal distribution of the individual shocks showed no progression along the fault plane as would be expected with a propagating fracture.
|
| 30. | If the fault plane terminates before it reaches the Earth's surface, it is referred to as a " blind thrust " fault.
