[M-TT37] [EE] Cryoseismology - a new proxy for detecting surface environmental variations of the Earth -

Tue. May 23, 2017 3:30 PM - 5:00 PM Poster Hall (International Exhibition Hall HALL7)

Several kinds of environmental signals associated with ocean-cryosphere-solid earth systems have recently been detected in the Antarctic and Arctic regions. Ice-related motions that generate seismic waves are generally termed ice-quakes (ice-shocks) and can be used to study glacial dynamics. Such kinds of cryoseismic sources are classified into the movements of ice sheets, sea-ice, oceanic tide-cracks, icebergs and the calving fronts of ice streams and glaciers. Cryoseismic waves are influenced by variations in environmental conditions, and the continuous study of their spatial and temporal variability provides indirect evidence of climate change. As glacial earthquakes are among the most prominent phenomena found recently in polar regions, new innovative studies from seismology as well as longterm monitoring of seismic signals in polar regions are expected to provide important new insights.

Taking these issues into account, the conveners invite many contributions to a special session on "Cryoseismology", which will cover the recent achievements on glacial-related seismic events and associated phenomenon observed in polar regions. Contributions based on seismic signals involving the dynamics of ice sheets, sea-ice, icebergs and glaciers are particularly encouraged. All related topics involving polar seismology are welcome, such as studies of crust and mantle structure in polar regions, comparison of tectonic and glacier-related seismicity, recent triggered earthquakes and active volcanoes, glacial isostatic adjustment (GIA), and harmonic tremor associated with cryoseismic events.
