Crustal motion of Chinese mainland monitored by GPS
摘要:
To measure and monitor the crustal motion in China, a GPS network has been established with an average side length of 1 000 km and with more than 20 points on the margins of each major tectonic block and fault zone in China. Three campaigns were carried out in 1992,1994 and 1996, respectively by this network. Here we present, for the first time, the horizontal displacement rates of 22 GPS monitoring stations distributed over the whole China and global IGS stations surrounding China, based on these GPS repeated measurements. From these results by GPS, we have obtained the sketch of crustal motion in China.

A facile route for the construction of functionalised spiro[n.4] systems through pinacol type rearrangement of appropriately designed cyclobutane derivatives with an application to a synthesis of (±)-α-cedrene is described.
