The data of icequakes series recorded in spring and summer seasons at Hans glacier, Spitsbergen, have been analysed. The determination of seismicity of the glacier, is based on temporary measurement networks placed on glacier surface. The following source parameters are analysed: seismic moments, apparent stresses, stress drops, sources diamensions and radiated seismic energies. A comparison of scalling relations for source parameters odf spring and summer series of icequakes has been made.
