“An international team of scientists just finished probing the depths of the Pacific Ocean offshore of Alaska and British Columbia, to better understand the Queen Charlotte-Fairweather Fault. During the past century, the 700-mile-long fault has generated at least half a dozen major earthquakes, and future shocks threaten coastal communities in both the United States and Canada.


Scientists from the U.S. Geological Survey, joined by colleagues from Natural Resources Canada, the University of Calgary, and the Sitka Sound Science Center in Alaska, spent 20 days at sea aboard the Canadian Coast Guard Ship, “John P. Tully.” The expedition covered more than 1,000 kilometers (620 miles) from the southern Haida Gwaii islands in British Columbia to Cross Sound near Juneau, Alaska. They were looking for clues to the future of a fault often compared to a more famous one in California…”

Scientists prepare to lower a piston corer off Haida Gwaii, British Columbia, to sample seafloor sediment near the Queen Charlotte-Fairweather fault. Expedition scientists are studying layers of sediment in the cores they collected to identify and determine ages of past earthquakes along the fault. This information will help them assess future threats to coastal communities in the U.S. and Canada.(Credit: James Conrad, U.S. Geological Survey. Public domain.)
