Observations of Greenland's Helheim Glacier link the process through which chunks of ice at the edge of a glacier break away, which has been hard to study, to seismically detectable events known as glacial earthquakes, which have been increasing in number in recent years. Because seismic signals from these events can be detected by instruments located all over the globe, it should be possible to use glacial earthquakes as proxies for the glacier edge breaking process, known as calving. read more
