Computer models that simulate the San Andreas Fault System have predicted this sort of crustal movement before. What's more, the San Andreas Fault is connected to another incredibly dangerous fault line, the Cascadia subduction zone. New observations confirm that the San Andreas Fault System, the massive tectonic boundary underneath much of California, is showing definite signs of movement , according to a post at the University of Hawaii's website. Scientists say it's crucial to monitor the San Andreas Fault because of its potential to unleash a catastrophic event on the West Coast. "Using this technique," Howell said, "we were able to break down the noisy signals to isolate a simple vertical motion pattern that curiously straddled the San Andreas fault."
