Fig. 5

Seismic reflection image showing “buried” magmatic intrusions along the RK01 profile. This image highlights tubular transparent bodies indicating volcanic conduits (shown by green arrows). Upwardly convex reflectors are interpreted to be sedimentary layers pushed up by the upwelling flow (blue arrows). The sudden disappearance of the high-amplitude reflector (acoustic basement) which is coincident with the distribution of the volcanic conduits (red arrow) also supports that the arc crust is highly disturbed by magmatic intrusions. On the western part of the basin, normal faults displacing the sedimentary layers are observed (black arrows)
