Southern California's portion of the San Andreas Fault has built up enough stress to unleash a major earthquake, a satellite study out Wednesday suggests.

The San Andreas Fault last triggered a major quake in 1906 — the famous San Francisco earthquake. The fault's southern link, which runs near both Los Angeles and San Diego, hasn't caused a major quake for at least 250 years, however.

Earthquake researchers have regarded the segment as the most likely spot for such a disaster for two decades, says geophysicist Kenneth Hudnut of the U.S. Geological Survey.

Geophysicist Yuri Fialko of the Scripps Institution of Oceanography in La Jolla, Calif., calls it "the king of all faults in California." Fialko, author of the new study in the journal Nature, says, "The southern San Andreas Fault is primed for a major earthquake. We cannot tell precisely when the next one will come. It could be tomorrow or it could be in 20 years."
