Mysterious tectonic fault zone found off California
A new method using fiber-optic cables pinpointed the previously hidden system—and it may reveal more seismic surprises around the globe.
The newfound fault system lies within Monterey Bay along the California coast.
Beneath the cerulean waters of Monterey Bay, just a few miles southeast of Santa Cruz, California, a never-before-seen cluster of faults has been found lurking on the ocean floor.
These newly spotted wrinkles in Earth’s crust, described in a paper published today in Science, are still largely a mystery. We can’t say much about their size, shape, or how active they are. Still, the findings show that even in one of the most seismically studied corners of the planet, fault maps of the ocean floor contain gaping holes.
