Abstract:

In this paper,ice avalanche was measured by digital trigger seismograph in Zhongshan Station to study the relation between ice avalanche regularity and nature surroundings (temperature,wind speed, etc.).It's important to the safe journey and the safety of scientists in Antarctica.It will also be of much help to the research of Antarctic glacier,iceberg and ice sheet.The result shows that the change of frequency of ice avalanche from January to September is parabolic with the mouth upwards and from October to December the frequency increases rapidly. As the temperature rises, the frequency of ice avalanche increases.The relation between the frequency and the wind speed is opposite.
