Short summary
Short summary
Obtaining the physical properties of ice sheets is important. In this study, we use seismic ambient noise to obtain the shallow S-wave velocity structure at the Dome A region. The result agrees with the ice-core data nearby and reveals radial anisotropy in the firn layer due to compaction and recrystallization processes. This study demonstrates that cultural seismic noise provides an effective and environmentally friendly way for the imaging of near-surface structures in Antarctica.

Short summary
Short summary
Previous studies focused on the ionospheric signature induced by straight tsunami waves. In this study, we apply the two-dimensional TEC maps derived from a dense GPS network (GEONET) to detect the reflected tsunami signature in ionosphere after the 2011 Tohoku earthquake. The results indicate not only the straight tsunami waves from mainshock, but also the reflected tsunami waves might have potential to induce ionospheric disturbances.
