Left: Epicenter location. Middle: The beach ball represents the deviatoric part of the mechanism. The posterior probability distribution (PPD) of the P (red) and T (blue) principal axes are also shown. Right: PPD of the moment tensor (MT) vector on a Riedesel-Jordan plot (red: MT vector and its PPD; orange: DC vector; green: CLVD vectors; blue: ISO vector. Triangles pointing downwards denote vectors on the lower hemisphere, whereas triangles pointing upwards represent vectors on the upper hemisphere.) Equal area projection of lower hemisphere is used.
