Seismological Measurements: Icequakes and Icevibrations

Chapter
Part of the GeoPlanet: Earth and Planetary Sciences book series (GEPS)

Abstract

In this chapter it is described how the two categories of seismic events were distinguished and how they are related to dynamic processes within the glacier. The distinction into icequakes and icevibration-type events was made by the author. The icequakes are associated with the velocity gradient of the ice flow in the marginal zone of the glacier; an analysis is made of the ice flow velocity changes in time. The icevibration-type events may be related to glaciodynamical processes occurring in the main stream of the glacier. Of importance are also resonant vibrations of large elements of the glacier. The field experiments in 1995 and 1999 are discussed.
