Session 1.3 GNGTS 2024 Fig. 3 (a) 2D velocity model, secton trace AB in Fig. 1a (n.b. the secton orientaton is SE-NW to have increasing distances rightwards). The black triangle is the 2011 earthquake (N. 37) with x-phase ; (b) Calculated ray paths for the earthquake N. 37; (c) calculated travel tme curves on the observed record secton of earthquake N. 37. The blue line shows the calculated direct P wave arrivals, and the red line is for the x-phase ; (d) Sketch of the possible petrology and thickness of the HVL.
