英文摘要 | Seismic interferometry can be spectacularly sensitive to temporal changes within the Earth. Zhan (2019, https://doi.org/10.1029/2019GL082411) analyzed 12 years of data from seismic stations situated near Bering Glacier, Alaska, that spanned a 2008-2011 surge. Interferometrically isolated glacier-crossing surface waves revealed an anisotropic seismic wave speed decrease during the surge. 1-D and 3-D modeling suggests pressurized englacial water flow being stored and guided by a network of basal crevasses, thereby sustaining high water pressure at the bed and supporting the high surge velocities. This result is demonstrative of the potential for seismic interferometry and other cryoseismological methods to continuously monitor and reveal changes within dynamic glacial-hydrological systems. |
