Fig. 9

a Surface projection of the fault planes of the M w 6.2 Ruisui earthquake (solid line) inverted from long-period surface waves (Lee et al. 2014) (black), from GPS inversion (blue), and from strain data inversion (red). The dotted line denotes the extension of each fault plane through the surface. The magenta dot localizes the hypocenter from CWB (121.348° E, 23.566° N), the thin black squares denote the first 5 days of relocated aftershocks, and the large black squares denote the strainmeter sites (1 HGSB, 2 SSNB, 3 CHMB, 4 ZANB). b–d 3D view of the faults planes showing the relocated aftershocks with the fault plane inferred from strain (red), seismology (black), and GPS (blue) inversions, respectively. The distribution of aftershocks exhibits three swarms, the largest (more than 50 % of the events) on the northeast and two similar swarms located at few kilometers southwest and arranged along a line striking at about 210–215°. They cover an overall area of about 15–20 km E-W and N-S
