GEOGRAPHY IN THE NEWS:
"We estimate the probability of having a magnitude 9 earthquake [in the Cascadian Subduction Zone] in the next 50 years is about 10 to 14 percent." The Cascadian Subduction Zone stretches more than 600 miles, from Vancouver Island, Canada, to Northern California and has a reputation for producing massive earthquakes (as well as the volcanic Cascade Range). The last major quake was 317 years ago, long before Seattle, Vancouver, and Portland were economically significant cities with large populations. news.nationalgeographic.com/2017/10/earthquakes-big-one-cascadia-seattle-geology-science/
