Nyiragongo - volcano in the Virunga mountains of Africa

Molten 'lake' of the volcano Nyiragongo

Nyiragongo - volcano in the Virunga mountains of Africa, 20 km north of Lake Kivu on the border with Rwanda Congolese territory. In 1882 there were 34 eruptions, including many periods where activity was continuous for many years.

The main crater is 250 meters deep and 2 km wide, it sometimes forms a lake of lava.
Nyiragongo lava unusually fluid and fluid, such features are caused by specific chemical composition - it contains very little quartz. Thus, during the eruption, lava flowing on the slope of the volcano can reach speeds of 100 km / h The temperature of molten lava in it up to 1200 ° C.

A research team from the Geneva volcanological company, having a four-course, went on a scientific expedition in the eastern Democratic Republic of the Congo.
The expedition was attended by eight people: the head of the Goma Volcano Observatory Dario Tedesco (Dario Tedesco), Jacques Barthelemy (Jacques Barthelemy), Pierre-Yves Burgi (Pierre-Yves Burgi), Frank Potet (Pranck Pothe), Mark Kaye (Marc Cailtet), Photographer Olivier Grunewald (Olivier Grunewald) and two mountain guide.
During the expedition, was investigated by the internal surface of the crater, took samples of volcanic gases and conducted measurements of the velocity changes in the level of the lake.

The view from the edge of the volcano, situated at an altitude of 3470 meters above sea level. At a depth of 250 meters is located lava lake - a real miracle of the African continent. (Olivier Grunewaid)

Permanent lake of lava in the crater of Nyiragongo volcano is the largest in the world. According to experts, the volume of the lake is about 8 million cubic meters. meters of lava. In 1977 and 2002, the lava lake overflows its banks, resulting in a destroyed part of the city of Goma in the Democratic Republic of the Congo. (Olivier Grunewaid)

Gas bubbles burst at the surface of the lake. It is constantly bubbling due to crustal movements. (Olivier Grunewald)

Seven members of the research expedition examining the territory of the lake, despite the fact that the lava is often overflows its banks. (Olivier Grunewald)

Prior to the expedition, all members of the research team took four courses. (Olivier Grunewald)

Researchers have come to the edge of the lake. Yet nobody has been able to implement this. (Olivier Grunewald)

A member of the team communicates by radio with the other, passing the data on the activity of lava and gases direction. (Olivier Grunewald)

Mark Kaye (Marc Cailtet) first reached the region surrounding the lake of lava. (Olivier Grunewald)

Frank Potet (Pranck Pothe) close to the lava. For such a close approximation, the wind must blow in the back, removing the heat. His colleagues send data on changes in the wind on the radio. (Olivier Grunewald)

Lava poured out of the crater. Year after year, the lava rises higher on the walls of the crater until the next eruption will not clear the crater. (Olivier Grunewald)

The most impressive caves flooded the world

Unusual "blue hole" is nothing like limestone caves, many of which were formed as early as the Ice Age. When the sea level rose, the water flooded the void, then destroying a set of caves.

Dean’s Blue Hole, Багамы

Blue Hole Dehaene is known worldwide as an ideal place for a free dive. It is situated in the bay to the west of the town of Clarence, the island of Long Island, Bahamas.

Blue Hole has a circular base, with a diameter of 25 to 35 meters (82-110 feet). After a descent of 20 meters (66 feet), significantly expanding the hole in the cave with a diameter of 100 meters (330 feet)

Proval Bimah, Oman

The failure of the Bimah , limestone crater filled with blue-green water, is a popular attraction of tourists coming to Kuarayat. It is located in Oman.

The failure is located 500 meters from the beach.

The water is salty because the lake is connected to an underwater cave with the sea. Great Blue Hole

Great Blue Hole - is situated in the center of Lighthouse Reef Atoll in the Belize Barrier Reef. The hole is circular sinkholes diameter of 305 meters, leaving a depth of 120 m

Blue Hole became famous thanks to the French explorer Jacques Yves Cousteau, who included it in the top 10 places in the world for diving. In 1972, on his vessel Calypso, he measured the depth of the hole and confirmed the theory of its formation.

Going down to the single U-boat in the hole, the expedition discovered a massive stalactites, some of which were placed at an angle of 10 ° -13 ° from the vertical, suggesting a geological shift and tilting lying below the plateau. Ik-Kil, Mexico

This is one of the most beautiful karst lakes, Ik-Kil (which means "place where the wind is born"). Each Cenote Maya considered sacred.

The height of the walls is about 25 meters, and depth - more than 50 meters

Krasnoe ozero, horvatii

Krasnoe ozero (Red Lake) - kastrovoe ozero. Glubina Krasnogo Ozer 287 m. Krasnoe ozero ävläetsä samym GLUBOKO Ozer v Europe.

The height of the lake above the sea level 281 m Elevation 528 m Red Lake is nearly three times smaller in area than the blue and is surrounded by steep slopes. On their side is equipped with an observation deck.

Nazvanie Ozer gave Krasnye skaly the beregu Ozer. Morning Glory Pool, SSA

It is a beautiful lake with unique properties in the National Park, Yellowstone in the U.S.

Just a small hot lake depth 2200 meters, of which there is a pair and still it changes its color from pale turquoise to deep purple, and then suddenly turns green. All this creates a multi-colored splendor of bacteria living here, which is very favorable temperature conditions.

His beautiful name it is no less beautiful lake is obliged to Elizabeth McGowan, wife of assistant manager Natsinalnym Park. She called him Convolutus - Morning Glory flower, bizarrely twisted flower bright blue. The same color, and was once the lake Morning Glory - bright blue with yellow and orange trim.

Kahuna Tortoise returns home

Meet Kahuna - tadpole sea turtle. Two years have passed since then, as a wounded animal biologists have saved the organization "The Power of St. Lucy." Turtle almost lost its flippers - one was almost completely torn off, and the second is also severely damaged. In addition, she had a serious bone infection that doctors tried to cure for several months. But this Sunday, after the doctor Center rescue sea turtles Cahoon returned to normal life, it's time to go home turtle. However, it is still radiorodarom supplied - not to lose.

That such a device was attached to the carapace Cahoon. It tracks the location of the turtles by satellite, showing the temperature of the water in which it is located, as well as the level of light. These data will be transmitted to the center of rescue sea turtles every time bug will float to the surface.
