2002年4月，在R/V L'Atalante的FAMEX巡航期间，沿着北北纬度23°至27°的下加利福尼亚州边缘记录了大量的水深和地震剖面。边缘的上斜坡沿Tosco - Abreojos断层系统（TAFS）呈现活跃的近期沉积物断裂。花状结构表明沿TAFS有走滑运动。右旋走滑断裂，在具有小伸展特征的地方，与沿TAFS预测的现今滑动和伸展速率一致。因此，TAFS属于下加利福尼亚地块的西部活动边界，但尚未完全转移到太平洋板块。
During the FAMEX cruise of the R/V L'Atalante (April 2002), swath bathymetry and seismic profiles were recorded along the Baja California margin from 23° to 27°N. The upper‐slope of the margin exhibits active faulting of recent sediments along the Tosco‐Abreojos fault system (TAFS). Flower structures evidence strike‐slip motion along the TAFS. Right lateral strike slip faulting, associated in places with small extensional features, are consistent with present‐day slip and extension rates predicted along the TAFS. The TAFS thus belongs to the western active boundary of a Baja California Block yet not totally transferred to the Pacific plate.
