Abstract:To better understand the structure and process of the Cocos plate subduction, we obtained the first Pn velocity and anisotropy model of the uppermost mantle in southern Mexico using the Pn tomography method and new ISC‐EHB data. This study confirms that the subducted Cocos oceanic plate exhibits mid‐oceanic ridge‐perpendicular anisotropy, and there is an arc‐parallel anisotropic structure beneath the subduction arc. The variation of the Pn velocity and anisotropy structure at the east and west ends of the flat… Show more
