🌋 New research indicates Southern California's San Andreas and San Jacinto faults are under the highest stress levels in 1,000 years, increasing the risk of a major earthquake.

🔬 A study published June 3 in the Journal of Geophysical Research, Solid Earth, highlights that a critical fault junction northeast of Los Angeles, Cajon Pass, may play a significant role in the magnitude of the next major quake.

📈 The research utilized computer simulations and geological evidence to model stress accumulation over the past millennium, finding that stress has reached up to 3.6 megapascals (MPa) on the San Jacinto-Bernadino section.

🚨 A new study published this month in the Journal of Geophysical Research reveals that stress levels on fault lines near Cajon Pass, California, have reached highs not seen in 1,000 years. This critical junction connects the San Andreas and San Jacinto fault systems, just 50 miles from downtown Los Angeles.

📈 Computer simulations indicate that the San Jacinto segment of the fault junction is the most heavily loaded, with stress estimations of 3.6. These rising stress levels heighten the concern for a potentially catastrophic earthquake in this densely populated U.S. region.

⚠️ Researchers warn that Cajon Pass could act as an "earthquake gate," influencing how ruptures spread. It has the potential to either halt an earthquake or allow it to jump between the San Andreas and San Jacinto fault systems, significantly increasing the size and reach of a potential event.
