On the left, are estimated vertical land motion (VLM) rates on the U.S. East Coast. The circles show the location of GNSS validation observations color-coded with their respective vertical velocities. Histogram compares GNSS vertical rates with estimated VLM rates. The standard deviation (SD) of the difference between the two datasets is 1.3 mm per year. On the right, is land subsidence (representing negative VLM) across the U.S. Atlantic Coast. Rectangles indicate the extent of subsisten…
