New earthquakes in the Gulf of California

Why is this of interest?

The Gulf of California sits at the northernmost end of an immense underwater mountain range called the East Pacific Rise, which extends across the Southeastern Pacific Ocean almost to Antarctica. Along much of this mountain range, lava wells up from below, causing the Earth’s crust to split apart, and forming what geologists call “spreading centers.”

Active spreading centers are hotbeds of volcanic activity. This causes cracks to form in the seafloor between the sections of crust, at right angles to the main axis of the spreading center. Geologists call these cracks “transform faults.”

Just south of the mouth of the Gulf of California, the East Pacific Rise changes from a series of spreading centers separated by transform faults to a series of transform faults separated by small spreading centers. The transform faults form a zigzag pattern below the seafloor of the Gulf. At the northern end of the Gulf, a single large transform fault continues up toward the northwest, where it connects with the San Andreas Fault system.
