A list of the biggest lakes of Russia rightly tops the pond, whose name got the word “sea”. The Caspian sea is on the border of Europe and Asia and is owned by five States: Russia, Kazakhstan, Turkmenistan, Iran, Azerbaijan. According to the latest data, its area amounts to 376 000 km2, but this figure is subject to strong fluctuations. Without exaggeration, the Caspian sea has become world famous not only because of its size, but also as one of the most problematic bodies of water.
In case the imbalance between the number entering the Caspian sea water and the amount of evaporation, in which the water level in the last century have steadily declined. About 30 years ago the climate of the Volga basin (which is the main supplier of water in the Caspian sea) became more humid, the parish has exceeded consumption – and began flooding the already developed coastal areas. Since 1820 here is oil and natural gas. the reserves which, according to expert estimates, to reach 20 billion tons.
The next largest is lake Baikal with the area of 31 500 km2, it is located between Buryatia and Irkutsk region. Baikal is the world record holder in several ways: it is the largest freshwater lake on Earth and here is the deepest (1620 Continue reading
Of greatest interest is the island of San Miguel with its historic Maritime capital, green fields and beautiful volcanic scenery. Originally San Miguel was composed of two separate Islands. The largest and most populated of the nine main Islands of the archipelago is 65 km from Settling in the capital of the island called Ponta Delgada, easy access to the rocky coast — to lakes in volcanic craters and hot springs emitting steam from the depths of the island.
The Western part of the island
In the North-West of the island of são Miguel is a giant crater of the volcano Caldeira das Sete Cidades (Caldeira das Network-Cidades), a circumference of about 12 km If the crater is not covered by clouds, is better it is visible from the observation platform Vistas do Rei where the trail starts, leading to its Western edge. At the bottom of the crater lies a little village Network-Cidades and six dark green lakes, separated by thin strips of land. It is believed that the crater was formed in 1440-ies, after the eruption, which was destroyed by the volcano that created the Western part of the island. Today the crater is covered with dense vegetation, although the first settlers called it a scorched shell.
In the main city of the Northern coast, called Continue reading
In Kyrgyzstan several hundred dangerous lakes, out of which 20 lakes are at the stage of breakthrough. These data lead experts on hydrogeology. Each of the lakes is a time bomb. According to the Ministry of natural resources, due to global warming in the country, glaciers melt and increases the volume of water in the lakes. According to the forecast of the Ministry, in the next two years can cut 12 to 15 lakes, situated in the Chui region. How serious is the threat of a breakthrough of mountain ponds and lakes was found Saltanat Kaldybaeva.
In Kyrgyzstan, from 2 thousand more than 300 mountain lakes are vulnerable to breaches. Such data led the head of the Kyrgyz hydrogeological expedition of the Ministry of natural resources Kamchybek Musuraliev. The last two years, the lake has not broken, but today, the fear among scientists is the lake TERS – tor located in the valley of Ala – Archa. The lake quickly filled connection with the intensive melting of snow and glaciers. On the road to this lake is the city of Bishkek and a number of settlements. The last time the lake TERS tor broke through in 1953 – year.
Each of mountain lakes has its own conditions of formation and breakthrough, says hydrogeologist Sergey Erokhin. There are many reasons for the breakout of the lakes Continue reading
