Abstract:
The current situation of the earthquake subsurface fluid monitoring network in China is briefly introduced. And then, some suggestion on adjustment and optimization of the network are proposed. ① Change the layout of the existing monitoring network so as to focus on the middle-western China, particularly to the west of 105°E. ② Increase the number of monitoring wells or springs up to approximately 1000. ③ Improve the quality of monitoring network, eliminate and transform those wells or springs that do not meet for the standards and requirements at all. ④ Optimize the monitoring items, focus on the monitoring of the wells or springs flows, the soil vapor in the vicinity of faults (main parameters are H
2, He, CO
2), and construct a soil vapor network. ⑤ Optimize the existing monitoring modes, establish the plane array observation and vertical multi-level three-dimensional observation. ⑥ Improve the existing digital monitoring technology.
