Seismological and Meteorological Research
Frequent strong earthquakes occur in Tibet, providing China with
facilities for earthquake prediction, countermeasures, and the study
of continental structural movements and their causes. The region's
seismologists have done much in seismological observation, surveillance,
prediction and investigation. At the same time, they have conducted
research on the features of seismotectonic belts, and clearly identified
Tibet's seismically active areas to assist in earthquake prediction.
This not only helps future surveillance and prediction, as well
as the study of geophysics and seismology, but also offers vital
seismic evidence for the region's economic construction.
In 1985, the Lhasa Geomagnetic Observatory won a silver medal
of International Geophysical Observation Centenary. As the country's
seismic undertaking developed, the world's most advanced digital
seismoscope was installed at the Lhasa Seismic Station in 1992.
Since Tibet Seismology was set up 20 years ago, about 480 issues
of the earthquake monitoring lists and reports have been printed,
and some books and investigative reports published. The book entitled
Earthquakes at Zayu and Damxung of Tibet, for example, won a third-class
award for science and technology progress at the state level, and
A Collection of Historical Materials About Earthquakes in Tibet
won second-class award for science and technology progress at the
regional level.
Weather reports are the most visible result of meteorological
work. Meteorological workers in Tibet provide both meteorological
information for the country and service for local economic construction.
Due to frequent natural disasters, the production level of agriculture
and animal husbandry is relatively low and is poorly capable of
withstanding calamities. Therefore, the Tibetan meteorological service
has been focused on agricultural production and animal husbandry.
In addition to short-term weather forecasts, meteorologists have
experimented with artificial weather creation in major agricultural
areas. Thanks to the efforts in preventing hailstorms but creating
rain in Chengguan District, Lhasa in 1987, agricultural production
escaped both hail and drought disasters, with grain output increasing
by more than 1.5 million kg over the previous year. Local people
happily praised the region's Meteorological Station, saying: "Eliminating
hailstorms and creating rainfall to conquer nature; serving agriculture
and enabling the poor to get prosperous''.
Closely related to meteorological services, scientific and technological
workers studied forecasting methods, and analysed the characteristics
of the shear lines of rainstorms on the Qinghai-Tibet Plateau. The
Research Institute of Astronomy and Calendar, set up in 1981, has
been studying the movement of the sun, the moon and stars, as well
as their changes in four seasons, publishing the Selected Points
of the 17th Cycle of the Dus-vkhor-lugs and other achievements.
