| Show Antarctica Ice Build-Up Increases By COOK Chronicle Staff Writer Earthquakes are becoming more frequent and more powerful clue to ice build-up in RECENT estimates of International Geophysical Year revealed the ice depth in Antarctica is increasing approximately twenty centimeters a The height of the ice caps above sea level a great amount of energy on the crust of the Calculations by Melvin director of the Institute of Metals and Explosive showed that this energy is the right order of magnitude and the right type of potential energy to account for global earthquake earthquakes tend to compensate the rapid rate of potential energy increase on the crust by the ice cap added or stress occur at the weakest points of the earth's crust with a frequency and magnitude determined by the strength at these fault A survey of earthquakes throughout the world indicates that the periods and magnitude of the earthquakes were irregular over short periods of time but regular during longer periods of THIS SURVEY also showed that large seismic activity was followed by long spans of inactivity while small seismic activity was correspondingly followed by short terms of The ice cap theory on earthquakes unlike the global thermal change account satisfactorily for all forms of |
