Mt Qomolangma Moving Northeastward, GPS Survey Shows
Mt Qomolangma, located on the China-Nepal border, is moving northeastward by six to seven cm peryear, according to the State Bureau of Surveying and Mapping.��
The mountain is moving at an azimuth angle of 54 degrees, according to a global position system (GPS) survey recently carried out by the bureau.��
Surveys over the past 30 years show that obvious changes have occurred in the area through crustal vertical movement, and experts said that these changes are the result of a large ruptureon the northern side of the Mt Qomolangma.��
Researches also showed that these changes correspond to seismological periods.��
Researchers found that the snow cover on the top of the MtQomolangma has been descending over the past three decades. "This has a connection with global warming," they said.��
Previously, China carried out surveys of Mt Qomolangma and the area to the north of the mountain three times in 1966, 1975 and 1992.��
Experts said that the recent survey is of theoretical value in geoscience and is of great significance in seismological forecasting and fighting against disasters.
