Thermally induced fractures or thermal cracks, and pronounced seismic events as snowquakes were studied at Mizuho Station, East Antarctica from June 1976 to January 1977. Fractures due to thermal stress were found in the uppermost 50 cm of the snow cover as a result of snow temperature decrease at t...
