NASA Aerospace Agency revealedstunning satellite image, which fell into a volcanic eruption. The release of lava was so powerful that it rose above the clouds and could be seen from the International Space Station. In recent times, a volcano over Raikkok, an uninhabited volcanic island in the northwestern Pacific Ocean, near Sakhalin, erupted in 1924 and 1778. In 1924, it subsided for almost 100 years and just the other day, on June 22, it erupted ash and volcanic glass. The "explosion of the Earth" was amazingly powerful and beautiful, as far as a natural cataclysm can be powerful and beautiful.
How does a sleeping volcano explode?
“How awesome is the shot,” says SimonKarn, a volcanologist at the Michigan Institute of Technology (picture you see at the very beginning of the article). “It reminds me of a classic photo of an eruption at the peak of Sarychev, which occurred in the Kuriles about ten years ago. The ring of white puffy clouds at the base of the column indicates that the surrounding air is drawn in and the water vapor condenses. Or it could be an upstream from the interaction of magma and seawater, because Raikkok is a small island, and the streams probably went into the water. ”

Centenary "dream" of the volcano was interrupted at about 4:00 local time on June 22, 2019, when a huge stream of ash and volcanic gases rose from its crater 700 meters wide. Several satellites — as well as astronauts on the International Space Station — watched a thick plume of smoke rise and then be sucked into a swirling storm in the North Pacific.
On the morning of June 22, astronauts took a photo.volcanic plume (image above), rising in a narrow column, and then crumbling in the so-called umbrella area. It is in this area that the flux and ambient air density become equal and the plume stops growing. The ring of clouds at the base of the column is water vapor.

How dangerous are volcanoes?
Specifically, in this case, the eruption at RaikkokNone of the people did not hurt, because the island is uninhabited and is far from civilization. But since the ash of the eruption contains sharp fragments of stone and volcanic glass, it poses a serious danger to aircraft. The ash of the eruption went up 13 kilometers, and some parts of the stream reached a height of 17 kilometers. For comparison, most aircraft fly no higher than 10 km altitude. In addition, the volcano literally destroyed all life on the island of Raikkok - now it has become “completely” uninhabited.
However, volcanoes are not only destructive. Perhaps it was thanks to the volcanoes on Earth appeared dinosaurs - read about it.
