Slow Slips (IMAGE) University of Washington Caption The study includes slow-slip events of about magnitude 6.6 generated on the Cascadia fault from 2007 to 2012. Along the bottom axis is the time in days, up to six weeks. The vertical axis is the distance in kilometers along the fault. Calculations looked at slipping for locations between the two dashed green lines, which spans roughly Olympia, Wash., to southern Vancouver Island, British Columbia. Credit H.
