Astronauts in space photographed a giant volcano erupting in the Pacific Ocean.
The Raikoke volcano, located on the uninhabited Kuril Islands in the Pacific Ocean,erupted for the first time since 1924.
For the first time in nearly a century, the Raikoke volcano in the Pacific Ocean erupted last week.
Raikoke is located in the Kuril Islands, which
are off the coast of Russia just north of Hokkaido, Japan. On June 22, a
mushroom-shaped ash plume rocketed skyward from the maw of the
volcano's 2,300-foot-wide crater.
The blast was so intense that it broke through
the clouds and could be seen from space. Satellites in orbit caught the
eruption on camera, and astronauts on board the International Space
Station could see it, too. The astronauts snapped the photograph above
showing the rising ash.
The plume may have exceeded a height of 10 miles, volcanologist Simon Carn said. NASA's Terra satellite captured a second image of the volcano (below), which shows brown volcanic debris.
Keeping track of volcanic plumes that breach that
stratosphere which starts about 33,000 feet (6.2 miles) off the ground
is imperative, since such eruptions can affect airplanes. The ash plumes
consist of fragments of volcanic glass and rock that can wreak havoc on
the machinery of nearby aircraft. Official volcanic-ash advisory
centers in Tokyo, Japan and Anchorage, Alaska have been tracking the
plume since the eruption and have issued several notes to aviators.
Eruptions like Raikoke's can also impact local
climates. When volcanoes fill the skies with sulfur dioxide and ash,
the particles cause more sunlight to be reflected away from the planet, and the Earth cools. It's thought that the eruption of Mount Tambora
in Indonesia nearly 200 years ago contributed to a severe summertime
cold snap the following year, which triggered killer frosts in New
England and Europe.
Carn confirmed that the eruption injected "large sulfur dioxide amounts" into the stratosphere.
But just 24 hours after the eruption, NASA
satellites showed that the dark Raikoke ash cloud had dissipated and no
longer stood out against the stratosphere's white canvas.
