The X axis is red. The Y axis is green. The Z axis is blue.
Red colors are inward and Blue colors are outward. The distance away from the origin indicates the magnitude of the first motion
Fault planes are shown as planes with their associated Normals, slip vectors (rake), and strikes.
Caveat/Warning Fault planes from Moment Tensor input are for the closest Double Couple.
P and T axes, i.e. sigma_1 and sigma_3, are also shown as arrows pointing in or out, along with the assocaited slip on the plane.
All of the components shown are configurable and can be hidden using the Settings menu in the top right corner.
