Scientists discovered a strange movement deep below the Earth’s surface near California’s biggest fault lines.

Geoscientists who analyzed thousands of small earthquakes that occurred near the San Bernardino basin near California’s San Andreas and San Jacinto faults discovered a strange and unexpected type of movement 10 km below the Earth’s surface.

Researchers think that the movement, known as “deep creep,” could be behind the unusual earthquake formations recorded in the region over the past 36 years.
