From 1990th, several seismological researches have been done by using the waveform data, phase arrival times and hypocentral data detected at Syowa Station. These investigations have been contribute to the studies of the earth's interior, particularly in and around the Antarctic plate. Current investigations include the following important topics concerning global, regional and local seismology & neo-tectonics:- lithospheric dynamics in an ice-covered environment;
- how lithospheric processes drive and may be driven by global environmental change (sea level, climate);
- the scale and nature of rifting as a process that has shaped the continent and dominated its evolution;
- the role of Antarctica as the keystone in the supercontinent formation and break-up throughout Earth's history;
- how the tectonic and thermal structure of the Antarctic lithosphere affect current ice sheet dynamics;
- age, growth, and evolution of the continent and processes that have shaped the lithosphere;
- the effect of improved seismic coverage on global models of the lithosphere, mantle, and core.
The followings are publications in recent few years regarding the Japanese contribution to seismic researches by use of the data from Antarctic stations including SYO.
