- The Raikoke volcano, situated on the uninhabited Kuril Islands within the Pacific Ocean, erupted final week for the primary time since 1924.
- The ash plume from the eruption was so giant that satellites in orbit and astronauts on the Worldwide Area Station may see it from house.
- Retaining tabs on giant eruptions is essential as a result of the ash comprises fragments of volcanic glass that may be hazardous to flying plane.

For the primary time in practically a century, the Raikoke volcano within the Pacific Ocean erupted final week.
Raikoke is situated within the Kuril Islands, that are off the coast of Russia simply 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 via the clouds and might be seen from house. Satellites in orbit caught the eruption on digicam, and astronauts on board the Worldwide Area Station may see it, too. The astronauts snapped the above displaying the rising ash.

The plume might have exceeded a peak of 10 miles, volcanologist Simon Carn mentioned in a NASA press launch.
NASA’s Terra satellite tv for pc captured a second picture of the volcano (under), which exhibits brown volcanic particles rising via clouds within the stratosphere.
Retaining monitor of volcanic plumes that breach that stratosphere — which begins about 33,000 toes (6.2 miles) off the bottom — is crucial, since such eruptions can have an effect on airplanes. The ash plumes include fragments of volcanic glass and rock that may wreak havoc on the equipment of close by plane. Official volcanic-ash advisory facilities in Tokyo, Japan and Anchorage, Alaska have been monitoring the plume for the reason that eruption and have issued a number of notes to aviators, NASA reported.
Eruptions like Raikoke’s may influence native climates. When volcanoes fill the skies with sulfur dioxide and ash, the particles trigger extra daylight to be mirrored away from the planet, and the Earth cools. It is thought that the eruption of Mount Tambora in Indonesia practically 200 years in the past contributed to a extreme summertime chilly snap the next 12 months, which triggered killer frosts in New England and Europe.
Carn confirmed that the eruption injected “giant sulfur dioxide quantities” into the stratosphere.
However simply 24 hours after the eruption, NASA satellites confirmed that the darkish Raikoke ash cloud had dissipated and not stood out towards the stratosphere’s white canvas.
