"Linked Faults: Cascadia Quake May Spark San Andreas Mega Disaster"
A new study from Oregon State University reveals that earthquakes in the Cascadia subduction zone may trigger catastrophic events along the San Andreas Fault, posing a dual threat to California.
- Researchers from Oregon State University analyzed 137 sediment cores from the Cascadia subduction zone and the San Andreas Fault, uncovering evidence of synchronized earthquakes.
- The study found geological records indicating that massive earthquake events in the Cascadia subduction zone could lead to significant seismic activity in California, increasing risk for North America.
- Sediment analysis revealed the presence of turbidites, which are layers of sediment deposited by underwater landslides, further supporting the link between the Cascadia subduction zone and the San Andreas Fault.
Why It Matters
Understanding the connection between these two geological zones highlights the potential for unprecedented destruction in North America. This insight is crucial for disaster preparedness and risk assessment in areas vulnerable to seismic activity.
