There is evidence of cyclic bulging associated with each of the past big quakes on Cascadia. There is evidence, for example, of land that was dry and forested when each cascadia earthquake struck, but were covered with tsnami sand deposite and then become innudated for hundred of years afterwards by brackish water after each quake, thus implying slow uplift between quakes, rapid subsidence during and after each quake. I don't know what is the degree of bulging now, but I do know there are formerly forested land that submerged with the 1700 quake that still remain submerged as coastal lagoons, with dead aspens sticking up through the water surface. So maybe the bulging has not reached its full extent and a quake is not imminent.
