“…This turn can cause the modern extension in the Baikal Rift System. The same displacement for the Amurian Block is established by results of the International Tidal Gravitational Section interpretation [Timofeev et al, 2006[Timofeev et al, , 2013. The velocity of the Amurian Block turn is evaluated as 0.083 ∘ per year according to the measuring in the Sikhote Alinh Geodynamic Net [Shestakov et al, 2011].…”

“…Active faults in central and East Asia were in detail characterized by Xu and Deng 1996], Trifonov et al [2002], Sherman [2014], seismic tomographic data -by Kozhevnikov and Yanovskaya [2005], Chen [2009], Huang et al [2009], Wang et al [2013] and others, heat flow (HF) intensity -by Tao and Shen [2008], Lysak [2009], Duchkov et al [2012]. Numerous Chinese, Russian and western scientists examined in their works up-to-date kinematics of the central Asian crust [Copley, 2008;Flesh et al, 2005;Fu et al, 2002;Gatinsky andProkhorova, 2014a, Gatinsky et al, 2011a;San'kov et al, 2005;Shen et al, 2000;Shestakov et ES3003 gatinsky and prokhorova: seismic active zones ES3003 Timofeev et al, 2006Timofeev et al, , 2013Zhao et al, 2010, and others].

In consequence of our investigations curried out during 2009-2015 we established the connection of maximal seismic activity in South Siberia, Russian Far East and adjacent countries of central and East Asia with zones divided numerous crust blocks or lithosphere plates and blocks. The investigation was fulfilled with the main purpose of definition the most active interblock zones, distinguishing levels of the maximal seismic energy releasing in them and regularities of its dissipation. Main methods of studying were the analysis of active faults and epicenters distribution with correcting boundaries of blocks and interblock zones, the calculation of the seismic energy volume releasing in these zones with construction of deep seismic sections and graphs of energy dissipation along transects across majority of interblock zones. The most active zones coincide with boundaries such blocks as the Pamirs, Himalayas, Tien Shan, Tarim, Amurian, Japanese-Korean, North Japan, Kuril-Kamchatka and Okhotsk as well as with boundaries between some of these blocks with North Eurasian plate. The volume of energy releasing in mentioned zones reaches up to 1 × 10 11−15 J, which is not far from the seismic energy releasing in subduction zones between the Pacific plate and Eurasia. Abnormal high seismic energy releasing depends of deep continuation of plate slabs in collision and subduction zones (the Pamirs, Himalayas, Kuril-Kamchatka), intensive displacements along strike-slips and thrusts due to collision processes and deep lithosphere unhomogeneity (Tien Shan, Altai), as well as of sharp changes of geodynamic conditions because of plate movement influence and supposed mantle plumes (North Mongolia, the Baikal Region). The examination of interblock zones is closely connected with the prediction of catastrophic earthquakes' possibility in some regions of central Asia that can be demonstrated at the example of the Kultuk earthquake in South Siberia and some others.

The coseismic geothermal changes of ground temperature observed at observatories near the epicenter of the 2020 Jiashi Ms = 6.4 earthquake in China, provide a unique opportunity to study heat generation and conduction in rock. Here, evolutions of rock temperature at the Xikeer, Jiashizongchang, and Gedaliang observatories, which are located at epicentral distances of 1.4, 27.42, and 50 km respectively, were analyzed. Significant coseismic geothermal changes of 0.0432 °C were observed at the Xikeer observatory at the depth of 33.38 m, at which clear diurnal variations can be observed. Smaller changes of ~0.0001 °C were observed at the depths of 12.3 and 22.8 m at the Xikeer observatory and 22.3 m at the Jiashizongchang observatory. The stress transfer induced by the coseismic rupture induced a rise in local ground temperature, but the magnitude of the change was relatively small. The larger amplitude change at the Xikeer observatory was caused by fluid infiltration. We note that diurnal variation has been recorded at the Gedaliang observatory, but the coseismic response is no longer in existence. The temperature increases at the hypocentral area were higher than expected in the ground due to the coseismic stress transfer, but the change attenuated rapidly with distance.
