Awakened from a 100-year sleep volcano destroyed all life around
Space agency NASA showed stunning satellite image, which has got a volcanic eruption. Lava Burst was so powerful that it rose above the clouds, and it can be seen from the International Space Station. In recent times the volcano over Raikoke, uninhabited volcanic island in the northwestern part of the Pacific Ocean, near Sakhalin Island, erupted in 1924 and 1778, respectively. In 1924, he fell silent for almost 100 years and just the other day, June 22, disgorged ash and volcanic glass. "The explosion of the Earth" was amazingly powerful and wonderful as it can be a powerful and beautiful natural disaster.
As a dormant volcano explodes?
"How stunning picture," said Simon Carn, a volcanologist at Michigan Institute of Technology (the picture you see at the very beginning of the article). "Reminds me of the classic picture of the eruption at the peak Sarychev, which occurred in the Kuril Islands about ten years ago. Ring puffy white clouds at said base of the column that the column is drawn into the ambient air and condenses water vapor. Or it could be an upward flow from the interaction of magma and seawater because Raikoke - a small island, and flows are likely to go into the water. "
That is the eruption of the Kuril Islands

Centennial "dream" of the volcano stopped at about 4:00 am local time on June 22, 2019, when out of its crater 700 meters in width ascended the huge flow of ash and volcanic gases. Several satellites - as well as the astronauts on the International Space Station - seen as a thick plume of smoke rose, and then drawn into the swirling storm in the northern Pacific Ocean.
On the morning of June 22 astronauts took a photo of volcanic plume (image above), climbing a narrow column, and then crumbled to the so-called umbrella area. It is in this area and the flux density of the surrounding air become equal and a loop ceases to grow. Ring clouds at the column base - is water vapor.
How does a volcano
How does an ordinary volcano
How dangerous volcanoes?
Specifically, in this case, the eruption on Raikoke none of the people do not hurt, because the island is uninhabited and far from civilization. But since the eruption ash contains sharp pieces of stone and volcanic glass, it represents a serious threat to aircraft. Ash eruptions rose to 13 kilometers, and parts Flow height reached 17 kilometers. For comparison, most airplanes fly no higher than 10-km altitude. In addition, the volcano literally destroy all life on the island Raikoke - now he was "absolutely" uninhabited.
However, volcanoes are not only destruction. Perhaps this is due to volcanoes on Earth appeared dinosaurs - read about it.
