Here, the recent movement characteristics in Tianjin area are analyzed by velocity field and time series results obtained based on the latest GPS observation data and the regional strain time series. The results show that (1) the velocity field in Tianjin area during 2013-2017 is lower than that of the surrounding area, and the horizontal motion is relatively weak; (2) GPS stations in Tianjin area move southeastward at a steady speed; the GPS stations in northern Tianjin rise at a steady rate, and those in southern Tianjin descend at a stable rate; (3) the regional strain in the study area accumulates at a steady rate, with no obvious change.
