Fig. 2: Seismic reflection profiles, Vp/Vs, and focal mechanisms.

Seismic profiles, Vp/Vs and focal mechanisms are shown along two NNE–SSW crosslines: a western side (crossline 63) and b eastern side (crossline 170), and c a WNW–ESE inline (Inline 250). Profile locations are indicated in Fig. 1b. In c the middle panel overlays the reflection profile. White dots mark interpreted faults (F1 and F2). In a blue dots indicate the low-amplitude reflection zone (LARZ), black arrows indicate a horizontal reflector, and red arrows highlights its discontinuities. In b red dots show the high-amplitude reflection zone (HARZ). In c relative location between LARZ and HARZ are shown. Green squares are geothermal power plants. Triangles indicate the seismometer locations, and the color of the triangles indicate the number of earthquake that the seismometer detected.
