Fig. 5From: Active-source seismic survey on the northeastern Hawaiian Arch: insights into crustal structure and mantle reflectorsa–d Close-up images of parts of the profiles shown in Fig. 2 and their interpretations. e–h Depth-converted seismic reflection images of the images in panels a–d; Vp structures are superimposed on each reflection image. The black lines show Vp at the e 205 km and f 575 km points on the EW line and at g the 198 km point on the NS1 line and h the 75 km point on the NS2 lineBack to article page
