Tectonic earthquakes of region of Donbass conductivity anomaly their possible connections

Possible nature of anomalous conductivity of DDD and Donbass is considered. The detailed description of materials concerning the earthquakes of Novodar and Roven is represented. The author makes an assumption that presence of graphite skins and formation of fractured porous massifs in rocks can be one of the possible trigger mechanisms.

Krivorozhsky earthquake of January 14, 2011

Geology-geophysical conditions of Kryvyy Rig earthquakes region are considered in limited by co-ordinates φ=47,45÷48,60 N and λ=32,5÷34,150 E area. Detailed description of materials of earthquake of the 14th of January 2011 is given. Author does supposition that presence there of graphite skins and formation of fractured-porous arrays in rocky breeds can be one of possible trigger mechanisms for local earthquakes.

Epicenters of East-European platform earthquakes within the Ukraine territory by data of instrumental supervisions and their connection with tectonics

The epicenters of earthquakes with magnitude M = 3,0–3,8 and less, registered at the Eastern European platform within the territory of Ukraine during the years 1963–2007, coincide with fault zones of the Earth's crust. The earthquake focus of December 25, 2007, M = 3,7 is located in the district of KrivorozhskoKremenchugskiy fault. According to the data of DSS it is determined that there are significant differences in the figures of layer velocities and in the cover thickness of the Moho surface on the opposite sides of the faults.
