We constructed a local relative-sea-level curve for eastern Maine from 14C dates on salt-marsh peats to evaluate potential Holocene neotectonic activity. This sea-level chronology indicates that, contrary to suggestions made previously, low elevations of late-glacial shoreline features in eastern Maine are not related to neotectonic activity during the past 5 ka. A comparison between seismicity and tide-gauge records leads to the conclusion that there is no relation between seismic activity and contemporary subsidence of eastern coastal Maine. We propose that eastern Maine has not been affected by anomalous subsidence during at least the past 5 ka.
