It is not possible to determine solely from a focal mechanism which of the nodal planes is in fact the fault plane.
32.
The fault plane responsible for the earthquake will be parallel to one of the nodal planes, the other being called the auxiliary plane.
33.
The mainshock could be felt as far away as Switzerland . with a north-south direction of compression, on a fault plane trending west-east.
34.
The fault plane, along which the two sides of the fault move, extends deep in the crust, usually an angle of 60 degrees.
35.
A simple fault plane model with a width of 12.8 km dipping to the southeast makes a reasonable match with the observed uplift pattern.
36.
"Slip " is defined as the relative movement of geological features present on either side of a fault plane, and is a displacement vector.
37.
In 1971, aftershocks from the Sylmar Quake spread out over the fault plane that ruptured 23 years later in the Northridge temblor, said Stein.
38.
This behavior has been reproduced by modeling the viscoelastic response of the megathrust fault plane with lateral variations in both convergence rate and frictional properties.

This behaviour has been reproduced by modelling the viscoelastic response of the megathrust fault plane with lateral variations in both convergence rate and frictional properties.
40.
A thrust fault has the same sense of motion as a reverse fault, but with the dip of the fault plane at less than 45?
