Vertical land motion (VLM) across the US Atlantic coast. a Estimated VLM rate. The circles show the location of GNSS validation observations color-coded with their respective vertical velocities. b Histogram comparing GNSS vertical rates with estimated VLM rates. The standard deviation (SD) of the difference between the two datasets is 1.3 mm per year. c Land subsidence (representing negative VLM) across the US Atlantic Coast. The black rectangles indicate the extent of study areas for Chesapeake Bay area and Georgia,…
