Scientists warn that the plate beneath Gibraltar arc will begin to shift toward the Atlantic within 20 million years.

Transform boundaries neither create nor consume crust. Rather, two plates move against each other, building up tension, then releasing the tension in a sudden and often violent jerk. This sudden jerk ...

Figure 1: Tectonic map of the southeastern Caribbean with shear-wave splitting measurements. The complex mantle structure and tectonic history of the region have been previously studied, but the ...

A hidden shard of ancient crust has been detected where California’s San Andreas system collides with the Cascadia subduction zone, reshaping how I understand the tectonic engine of the West Coast.

This paper presents a new synthesis of Franciscan Complex tectonics, with the emphasis on the pre-San Andreas fault history of these rocks. Field relations suggest that the Franciscan is characterized ...
