We present an application of the fracture-band model to the study of icequake series recorded in June 1999 at Hans glacier, Spitsbergen. The determination of seismicity of the glacier is based on two measurement networks. Using the calculated data of seismic moments, stress drops, and seismic radiated energies, we are able to calculate for each event in series the values of seismic efficiency, the total released energy, the ratio of tensile stress to shear stress, the ratio of source thickness to source radius, and the damage factor.
