Krasnodar GRES Project Volume I11 Environmental Assessment

The project site is located in a seismic region. The seismicity of the project
construction site, with due considerations for ground conditions, resonance
phenomena and ground water level, is 7 points on the MSK-64 scale with an
average repletion period of 1000 years. The maximum acceleration amplitudes
are not in excess of 0.04-0.08g.
3.2.4 Climate
The region where the project will be located borders on mountainous relief 50 km
south of the Great Caucasus Ridge. The surrounding relief is relatively flat, low
hilly, cut by shallow ravines with flowing creeks at the bottom. The climate of
the project region is temperate-continental. The proximity of the Black Sea and
high ranges of the Major Caucasus produce considerable effects on the general
atmospheric circulation. With active inflow of cold the absolute minimum air
temperature in winter may reach minus 36-38 deg. C, while in warm weather it
reaches plus 18-20 deg. C. Summer is hot, dry and long (from May to
September). The absolute air temperature may reach plus 40-45 deg. C. The
relative humidity ranges from 69% to 82%. Average yearly precipitation is about
