Crustal Uplift around Syowa Station, Antarctica

There is a great deal of evidence concerning crustal uplift, after deglaciation, in the vicinity of Syowa Station (69.0°S, 39.612) from tide gauge data, seismic evidence, elevated beaches, marine terraces, etc. The geomorphological and tide gauge data show that crustal uplift is going on around Syowa Station. Local earthquake activity corroborates the crustal uplift, and it is an intermittent phenomenon. Sea level falling of 4.5 mm/y was found using data in 1975–1992. This falling rate is consistent with geomorphological data. A route for repeat leveling survey was established in East Ongul Island. No appreciable change was observed for the last 14 years. The observations from repeat leveling measurements suggest no significant changes, which further supports the idea that the crustal uplift is not a tilt trend movement but a block movement.
