Moment Tensor Solution
The figure above shows a visual representation of the faulting process derived from the estimated moment tensor. Shaded areas show quadrants of the focal sphere in which the P-wave first-motions are away form the source, and unshaded areas show quadrants in which the P-wave first-motions are toward the source. The two circles represent the axis of maximum compressional strain resulting from the earthquake (in black, called the "P-axis") and the axis of maximum extensional strain (in white, called the "T-axis").
