In 2015, IGL obtained a Sino-Russian cooperation and exchange project jointly funded by National Natural Science Foundation of China (NSFC) and Russian Foundation For Basic Research (RFBR) - “Research of meta-instable conditions of faults of seismoactive zones in China and Russia as fundamental basis of the forecast of earthquakes: by results of complex monitoring of experimental models and natural objects”. Russian cooperator is the Institute of the Earth Crust, Siberian Branch of the Russian Academy of Sciences. The Institute of the Earth Crust, Siberian Branch of the Russian Academy of Sciences is a state-level scientific research institution researching tectonophysics, continental macroseismicity and diastrophic evolution.

From July 27, 2016 to August 4, 2016, at the invitation of the Institute of the Earth Crust, Siberian Branch of the Russian Academy of Sciences, Associate Researcher Chen Shunyun, Associate Researcher Wang Kaiying, Assistant Researcher Ji Yuntao and Senior Engineer Song Chunyan went to Russia for 7 days’ Sino-Russian international cooperation and exchange.

During the stay in Russia, they mainly carried out work in the following three aspects:

1)     Academic discussion. Chinese side and Russian side each made four academic exchange reports based on their respective academic progress and cognition. The meeting was presided over by Academician Shermen S.I. of the Institute of the Earth Crust, Siberian Branch of the Russian Academy of Sciences. The content of the exchange reports involves multiple aspects, such as: fault sub-instability, field observation, seismicity, strong earthquake prediction and experimental research. The atmosphere of academic exchange was good.

2)     Field work and visit of survey sites. The team leader was Professor Bornyakov S.A. Firstly, they carried out field fault study of Baikel Rift Zone. Professor Bornyakov S.A. introduced in details the formation and evolution processes of faults and mechanical models; secondly, they visited the site of crustal deformation and temperature observation. This survey point is powered by solar cells and transmits data through a wireless network. Further, the results of on-site temperature and deformation observation were analyzed and discussed. The correspondence between temperature and deformation is highly consistent with the observation result obtained by our laboratory.

3)     Tectonophysical simulation experiment. In a Russian tectonophysics laboratory, tectonophysical simulation experiment of a mechanical model for the intersection (triple junction) of three faults: Xianshuihe Fault-Longmenshan Fault-Anninghe Fault was conducted. Through repeated discussion and continuous improvement of the experimental scheme, seven simulation experiments of tectonic deformation were completed.

In general, although the time was short, the outcome was fruitful. The two parties of the cooperation both made active involvement, the academic exchange was sufficient, and field work and experimental research were better than expectation. Particularly, the academic achievements in the following two aspects have the potential of further cooperative research: Firstly, the field observation result of temperature and deformation found field observation evidence for the physical relation between heat and deformation obtained in a laboratory; secondly, the tectonophysical simulation experiment of a mechanical model for the intersection (triple junction) of three faults: Xianshuihe Fault-Longmenshan Fault-Anninghe Fault  provided new experimental data for the tectonic deformation model of the triple junction
