Geodetic-leveling data indicate that a large patch of the interpolate decollement (the main fault between the North American Plate and the subduction oceanic plate) off southern Oregon is locked. This and other evidence has led to proposals that an earthquake with a magnitude as large as 9 could someday devastate the
