Regional bathymetric map of the southwestern Ryukyu subduction zone between Taiwan and Iriomote Island. The southwestern Ryukyu Trench (shaded orange) terminates at Gagua Ridge, which separates the Huatung and West Philippine Sea basins. Several large canyons (yellow broken lines) incise the narrow slope off eastern Taiwan and extend into the Huatung Basin. CR, coastal range; HB, Hoping Basin; NB, Nanao Basin; ENB, East Nanao Basin; HTB, Hateruma Basin; Ir, Iriomote Island; Is, Ishigaki Island; HLC, Hualien Canyon; TTC, Taitung Canyon; and Lu and La, Lutao-Lanyu Ridge (i.e., the Luzon arc). The square indicates the area shown in Fig. 2a, and the red solid line the location of seismic reflection profile line 89 (Fig. 2b)
