NORA policies. Quantitative estimates of land-level change
during the giant AD 1700 Cascadia earthquake along the Oregon
coast are inferred from relative sea-level changes reconstructed
from fossil foraminiferal assemblages preserved within the
stratigraphic record. A transfer function, based upon a regional
training set of modern sediment samples from Oregon estuaries,
is calibrated to fossil assemblages in sequences of samples
across buried peat-mud and peat-sand contacts marking the AD
1700 earthquake. Reconstructions of sample elevations with
sample-specific errors estimate the amount of coastal subsidence
during the earthquake at six sites along 400 km of coast. T
