a Depth slice at 80 km, b Depth slice at 160 km, and c a cross-section at latitude 28.5° extending from longitude 100° to 132°. The tectonic boundaries in a, b are the same as Fig. 1. Geological interpretation sees the text. White dashed line in a marks the position of latitude of 28.5°. White dots denote earthquakes within 1° of the profile.
