Undulated Slip Surface
If the undulated surface is considered (on scale 1 to 10 m) - it is possible to account for slip surface waviness by angle ν:
where: | α | - | slip surface gradient |
αi | - | gradient of the i-th fault of the slip surface |
The waviness increases the tensile strength τ on the slip surface by Δτ:
where: | σn | - | normal stress acting in the direction normal to the slip surface |
ν | - | waviness angle |
