"Linked Fault Lines: A Dual Threat to Earthquake-Prone Regions"

Researchers have found that the Cascadia subduction zone and San Andreas Fault can trigger earthquakes in each other, raising concerns for the West Coast of the United States.

• The study from Oregon State University reveals that an earthquake in the San Andreas Fault may instigate seismic activity in the Cascadia subduction zone, and vice versa.
• Historical data indicates a complex relationship between the two fault lines, with sediment layers from turbidite deposits providing evidence of past interactions between the Cascadia subduction zone and the San Andreas Fault.
• Understanding these linked fault lines is crucial for disaster preparedness, as an earthquake in one zone could lead to devastating effects across the West Coast of the United States, affecting millions.
