Ridge subduction
WebTo be clear, the probability of a Cascadia Subduction Zone earthquake happening in the next 50 years is about 1-in-6 (17%). So, much greater than zero chance, but much less than a guarantee. Like any risk in life, you should be prepared, follow state and local guidelines about preparation. http://en.dzkx.org/article/doi/10.6038/cjg2024P0107
