Seismic Wave Velocities in the Hans Glacier, Spitsbergen
Direct measurements of P and S wave velocities were performed by a special seismometer array on the Hans Glacier, in the vicinity of the Polish Polar Station Hornsund, Spitsbergen. Artificial quakes were generated at a point of central location between the seismometer sites. The calculated velocities are: VP = 3,620 m/s, VS = 1,780 m/s. The thickness of glacier under the source, as estimated on the basis of the travel times, is h = 90 m.
