In the event of a Cascadia Subduction Zone earthquake, the most vulnerable 220 acres in Portland, and potentially in the Northwest, is located in the Willamette River’s Portland Harbor where over 90 percent of Oregon’s liquid fossil fuel supply is stored, according to a recent report by EcoNorthwest. The resulting fuel spill would send millions of gallons of oil and gas into the river, adversely impacting salmon and steelhead in the Willamette and Columbia rivers, many of which are listed under the federal Endangered Species Act.
