The world’s largest volcanic lake is located on the island of Sumatra. in Indonesia. This is Toba, the largest lake in Indonesia. In the center of the island of Sumatra is the Great Sumatran fault: here one can feel the slightest changes of the Indo-Australian and Eurasian plates which makes the whole area one of the most seismically active on earth. Near this dangerous fault and is Toba.
The lake is a consequence of the most powerful in the last 25 million years of volcanic eruptions. It was about 73 500 (±3500) years ago and, according to experts, was in force in 8 points.
The Toba Caldera is located in the North Central part of Sumatra. From the equator it is separated about 200 km It was formed from the collapsed during the eruption of three volcanoes calderas, pulled a part of the land. It subsequently filled with water. In the middle of the lake Toba is Samosir island is the result of extrusion of lava from the center of the Caldera, and now gradually resurgent lava dome, possibly the largest on Earth. However, earlier it was a Peninsula. And the island of Samosir became after 1906, the Dutch paved the channel depth Continue reading
In the Leningrad region in the village of Lopukhinka there is an amazing lake with an unusual sky-blue color of the water the radon lake. Rather it is a huge ravine or even several water basins with a depth of tens of meters. Along its bottom runs a small river, Rodica. About the building Lopukhinsky high school slope of the ravine is a sheer cliff, folded limestone. These ancient limestone, of Paleozoic age, you can easily find the remains of fossilized fauna of marine mollusks and even ancient fossils – trilobites. From cracks, splits limestone, flow numerous streamlets of springs that flow into Rudico.
The pond is incredibly clear, at the bottom there is no plants, no plankton, no any other animals. In addition, the lake has healing properties, and next to it you can make interesting discoveries.
Radon lake are artificial in origin, formed by the construction of 2 dams in the upper reaches of Radici — the length of the upper lake is about 200 meters, 50 meters — lower lake length of 550 meters, a width of 40-60 meters.
In the early XX century on the sources feeding the lake Lopukhinsky, drew the attention of renowned hydrogeologist N. F. Cellars. He found that their heavenly color of a pond Continue reading
“Death valley” is a word in daily use among many peoples of the world. About the sinister places, in which dies and unexplained things are happening, people tend to speak in a low voice. There is such a point and in Russia. One of the most famous “valleys of death” is in Transbaikalia
There are strange rumors about this secret place, located in the upper reaches of the river Vilyui. The name also speaks for itself – Eluu Cherkekh. In translation from the Yakut means “Valley of death”. For many years, local hunters bypass this blank area.
Sometimes in the sky you hear a roar, flashing dazzling white crosses, and on earth there are “metal monsters”. There is also retold the story of shepherds and hunters, who found a piece of iron “it is absolutely like nothing on earth”.
It is possible that all these puzzles have a terrestrial origin. Most likely, we are talking about the dropping of spent rocket stages. And since satellites (spy satellites, scientific stations and space ships) from year to year are displayed along well-defined trails, on the Earth’s surface formed a “zone” where almost piled in heaps of twisted aluminum tanks of launch Continue reading
