Study Reveals Potential Double Earthquake Threat on West Coast
A recent study has highlighted a potential connection between two major fault systems on North America's West Coast: the Cascadia subduction zone and the San Andreas fault. Led by marine geologist Chris Goldfinger from Oregon State University, the research suggests that seismic activity on one fault could trigger earthquakes on the other. This finding is based on the analysis of sediment cores from the ocean floor, which preserve geological history and indicate a synchronization between the two fault systems. The study identified three instances in the past 1,500 years where earthquakes on these faults occurred within minutes to hours of each other, suggesting a possible pattern of closely timed seismic events.
