Abstract : CONCLUSIONS: (1) New releveling data and tidegauge data make it possible to revise the map of rates of recent vertical movements of the crust in the western part of the European part of the USSR. The rates on the revised map vary from -6.3 to + 14.6 mm/year, with errors from = 0.7 to = 1.1 mm/year. (2) The trend of recent movements in the interval between relevelings is maintained on the whole. (3) From data of releveling repeated over 5-10 years, and also from series of tidegauge observations with durations up to 10 years, exaggerated rates were obtained with errors of the order of magnitude of the rates. (4) To determine the rate of land movement from tide-guage data, only stations with a period of observation greater than 30 years should be used. (5) Relevelings for the study of recent movements should be done over not less than 15 years (this figure should not be extended to seismically active areas). (6) Study of the period of recent movements should proceed on the basis of large quantities of statistical data. (Author)
