Chinanews, Lhasa, July 20 - The highest manned seismological station was put in trial operation in the northern part of Tibet Autonomous¹ Region², to monitor the small-scale earthquakes there. The station was also built as an important supply to the national earthquake monitoring network.

The station was first put in use during the 9th Five-Year Plan Period (1995-2000), but at that time it had no proper instrument to monitor small-scale earthquakes, which are common in northern Tibet and along the boarder between Tibet and Xinjiang and the border between Tibet and Qinghai.

Thus the station was upgraded³ to its current scale. Now it can sense very small earthquakes (less than 1 on the Richter scale) that occur within the range of 250 km. It can even record the vibration⁴ caused by a moving car.

So far, the station is in normal operation, and has recorded all the earthquakes that had occurred.
