SummaryEastern North America is generally thought to be "stable" -- meaning that most areas are deforming very slowly (rates below 1 mm/yr), although some areas have earthquakes that can reach magnitude 6-7 infrequently. As a result, few measurements of ground deformation in the region have been made. However, based on a limited reconnaissance InSAR study, we have found several areas of ground deformation exceeding 1 cm/yr in the region caused by human activities and perhaps even some natural processes. We suspect that deformation may be under-appreciated because of the lack of observations. Therefore, we propose to use archived TSX data to search for additional areas of ground deformation in Washington, DC and other areas of interest with sufficient data that should be further studied with satellite and ground observations.
