🌋 Why California Is So Prone to Earthquakes

California sits along several major fault lines, including:

• San Andreas Fault
• Hayward Fault
• Calaveras Fault

These fault systems make the region one of the most seismically active areas in the United States.

The recent quake also occurred near the site of the historic 1989 Loma Prieta earthquake, which caused significant damage across the Bay Area.
