The PIs will carry out a high-resolution seismic survey to image the structure of the southern flank of the Gorda Escarpment and the transiition between the Escarpment and Mendocino Ridge. The survey will be carried out to determine whether there are proto-San Andrea's faults in the Vincaino Block or sutures between blocks and the Ridge. The timing of the uplift of the Escarpment will be constrained. This will lead to an insight into the processes that are responsible for the transfer of the Gorda Plate crust to the Pacific Plate and the understanding of the plate boundary dynamics and evolution.

PI将进行高分辨率地震勘测，以成像Gorda陡崖南翼的结构以及陡崖和门多西诺山脊之间的过渡。 这项调查将进行，以确定是否有原始圣安德烈的断层在卡维诺块或缝合之间的块和山脊。 陡崖抬升的时间将受到限制。 这将导致深入了解负责戈达板块地壳向太平洋板块转移的过程，并了解板块边界动力学和演化。
