Abstract

Seismic Monitoring of Glacier Activity:
2013-01-01 to 2013-12-15
To study and understand the processes generating icequakes, it is essential to combine expertise from both fields seismology and glaciology. Svalbard glaciers have been studied for many years to determine mass changes in relation to global sea level and climate. Recently, the increasing importance of dynamic glacier activity has been acknowledged, particularly due to loss of ice through calving and surging. To better characterize dynamical glacier activity, we aim to use available seismic data of the past 15 years recorded on permanent seismic stations on Svalbard and independent glacier observations to investigate regional icequakes, both for patterns in their temporal and spatial distribution as well as their waveforms. The key elements of this study are the improvement of source location estimates for glacier-related seismic events on Svalbard and the use of adapted automatic pattern recognition methods to classify their signals. A temporary seismic monitoring experiment at a calving glacier on Svalbard will provide the link between local seismicity on a single glacier and the regional scale observations.
