Plot Focal Mechanism Solution in a Spherical Plot — stereo_fms • structr

Shows the principal faults associated with a stress tensor and a given friction coefficient using the focal mechanism / beach ball style.

Usage

stereo_fms(
  sigma,
  friction = 0.6,
  fill = TRUE,
  col = "#BEBEBE80",
  border = "black",
  ...
)

Arguments

sigma: symmetric 3x3 matrix. The (reduced) stress tensor.
friction: numeric. Coefficient of friction (0.6 by default)
fill: logical. Whether to fill the inner part of the small-circle? FALSE by default.
col: fill color of quadrant
border: Color of the filled small-circle's outline (ignored if fill=FALSE)
...: optional plotting parameters passed to stereo_greatcircle()

Value

"Fault" object
