Abstract: The paper is devoted to the results of studies on mud volcanoes of the Shamakhi-Gobustan region (Azerbaijan) and Sakhalin Island (Russia) in the aspect of intensifying their activities related to seismicity in adjacent areas. Monitorings in Azerbaijan and Sakhalin Island were carried out at different periods and were based on measuring temperatures and flow rates of active mud volcanoes. In addition, some distribution regularities of gas-hydrogeochemical indicators were established in connection with seismicity, based on monitoring of the chemical composition of gas and water ejected during the daily activity of the mud volcanoes. Depending on the magnitude of the seismic event in the periods before and after seismic activity some anomalous changes were recorded in the composition of fluids (for gases: CO2, CH4, N2, He and for waters: B, SO4, Cl) carried to the Earth's surface by mud volcanoes for both study objects. Earthquakes with a large magnitude affect the temperature regime in the microforms of mud volcanoes too. During the activation of mud volcano, the channel ejects fluids from ultra-depth opens wider, which leads to an increase in the flow of gases from deep sources, in which the predominant components are CO2 (in Shamakhi-Gobustan) and CH4 (on Sakhalin Island).
Key words: mud volcanism, fluids, monitoring, seismicity, Shamakhi-Gobustan, Sakhalin Island, gryphon activity.
