a Fault plane solution and source time functions of the deviatoric and volumetric components of the source moment tensor after INPAR inversion27. The volumetric component encompasses one-third of the total tensor and has a longer duration than the deviatoric component. b Genetic algorithm inversion results with confidence error areas28. T, P, and B are the tensional, compression, and null axes, respectively. L is the vector describing the total mechanism; d is the double-couple (DC) vector; l and l’ are the compensated linear vector dipole (CLVD) components along the tensional and pressure axes; i represents the volumetric (V) component. The distance of L from vectors i, d, l, and l’ indicates the share of the V, DC, and CLVD components (35, 64, and 1%, respectively). The small confidence area of vector L denotes the robustness of the solution and the reliability of the volumetric component. Downward-pointing triangles are vectors in the lower hemisphere, upward-pointing triangles are vectors in the upper hemisphere. The source time function is normalized to the maximum source time function of the population for a unitary tensor. The scalar moment is normalized to the value given in Supplementary Table 2.
