Improving our understanding of hazards posed by future large earthquakes on the Cascadia Subduction Zone requires advancements in the methods and sampling used to date and characterize past events.
What do a backhoe, expanding foam, half-ton concrete blocks, and a 100-meter-long hillslope slide have in common? All were part of reviving the U.S. Geological Survey’s experimental debris flow flume.
Comparing recent GPS data with a longer record of sea level along the western coast of North America allows researchers to home in on interseismic deformation above the Cascadia megathrust.
Living in Geologic Time: Every one of the Pacific Northwest’s volatile volcanoes is likely to erupt again before the range goes extinct.
Researchers examine the rings of drowned trees in landslide-dammed lakes for clues to today’s earthquake hazards in the Pacific Northwest.
While megaquakes occasionally occur along the Cascadia margin, smaller but more frequent crustal earthquakes are a more immediate threat, according to a natural hazards expert.
