Fault deformation gradient tensor — fault

Creates the fault deformation gradient tensor from displacement components. If the dip direction is know, the tensor will be rotated into the geographic reference frame.

Usage

fault_tensor(displacements, dip_direction = NULL)

Arguments

displacements: data.frame containing the strike slip, the heave, and the vertical throw of the fault's displacement components.
dip_direction: (optional) dip direction in degrees. If NULL, the fault tensor will be given in the fault displacement coordinates. Otherwise, the tensor will be in the geographic reference frame.

Details

x axis of tensor = heave, y = strike slip, z = vertical throw (positive for thrusting, negative for normal faulting)

Examples

if (FALSE) { # \dontrun{
fault_tensor(
  displacements =
    data.frame(strikeslip = 2, verticalthrow = -5, heave = 3),
  dip_direction = 0
)
} # }
