Study Reveals Potential Double Earthquake Threat on U.S. West Coast
A recent study conducted by researchers at Oregon State University suggests that the Cascadia subduction zone and the San Andreas fault, two major fault systems along North America's West Coast, may be more interconnected than previously believed. The study indicates that seismic activity on one fault could potentially trigger earthquakes on the other, leading to closely timed seismic events. This finding is based on the analysis of sediment cores from the ocean floor, which preserve geological history and reveal patterns of past earthquakes. The research highlights the possibility of a 'synchronization' between the two fault systems, which could result in simultaneous earthquakes affecting multiple regions such as San Francisco, Portland, Seattle, and Vancouver.
