   Southern California Faults Reach Highest Stress Levels in 1,000 Years

   New research indicates the San Andreas and San Jacinto fault systems are under extreme geological stress. These levels are the highest recorded in a millennium. Experts warn this pressure increases the risk of a major earthquake.

   What's confirmed:

   • The San Andreas and San Jacinto faults are experiencing their highest stress levels in 1,000 years.
   • Stress on tectonic plates has built up because a major rupture has not affected the greater Los Angeles area for over 100 years.
   • Pressure is building where two major fault lines converge at Cajon Pass.

   Still unconfirmed:

   • Researchers believe people should expect to experience large earthquakes in their lifetimes.

   California Fault Systems Reach 1,000 Year Stress Peak

   The San Andreas and San Jacinto fault systems are currently experiencing their highest tectonic stress levels in 1,000 years. This critical loading increases the risk of a major earthquake in Southern California. A specific junction 50 miles from downtown Los Angeles is accumulating this stress.

   What's confirmed:

   • The San Andreas and San Jacinto fault systems are at their highest stress levels in 1,000 years.
   • A critical junction where two major fault systems meet is 50 miles from downtown Los Angeles.

   Still unconfirmed:

   • A huge earthquake could be about to arrive near Los Angeles.

   California Fault Systems Reach 1,000-Year Stress Peak

   A University of Hawai'i at Mānoa study finds the San Andreas and San Jacinto fault systems are critically loaded. Tectonic stress levels are at their highest point in 1,000 years. This state increases the risk of a major earthquake in Southern California.

   What's confirmed:

   • The San Andreas and San Jacinto fault systems have reached their highest tectonic stress levels in 1,000 years.
   • A study from the University of Hawai'i at Mānoa describes the system as critically loaded.
   • The current stress levels increase the risk of a large earthquake in California.

   Still unconfirmed:

   • The Cajon Pass may act as an earthquake gate determining if a rupture spreads across both faults.
   • A simultaneous rupture of the San Andreas and San Jacinto faults could affect millions.
