The quake is the latest in a series of tremors that have struck the region in recent months.
It is unclear how the holes were formed, although marine trash could partly be responsible.
"The Garlock Fault has been quiet for a long time. But there's geologic evidence that there have been large earthquakes on it," the lead author of a new study said.
Scientists have uncovered a geological explanation for why some volcanic eruptions are more explosive than others.

The desert's age has been the topic of debate for decades among scientists.
The photo was taken by the ExoMars Trace Gas Orbiter—a spacecraft developed by the European Space Agency and the Russian space agency Roscosmos.
The land mass, now called Greater Adria, split from supercontinent Gondwana 240 million years ago during the Triassic Period—but was forced into the Earth's mantle 140 million years later, when it came into contact with what is now Southern Europe.
For the study, scientists recreated the extreme pressure and temperature of the moon's interior in the laboratory.
The 'abiotic' methane may hold clues about its presence elsewhere in the solar system, researchers say.
Warmer conditions on Ancient Mars increase the possibility that life developed there, according to researchers.
The magnetic field last flipped 795,000 years ago in an event called the Matuyama-Brunhes reversal.
When exactly plate tectonics emerged and how it has evolved through time are two of the most significant and hotly debated questions in Earth sciences today.
Earth is not the only place that experiences quakes.
Discovery could help our understanding of how and when the magnetic field was turned on.
