The Raikoke Volcano, inactive for a long time, has actually woken up from its sleep. The volcanic island remains in the Kuril Island chain, near the Kamchatka Peninsula in Russia. Unlike its more volcanically active neighbours, Raikoke has actually been inactive considering that 1924.

Thanks to astronauts on the International Spaceport Station, we have stunning pictures of the eruption.

The blessed occasion happened on June 22 nd at about 4: 00 am, when the circular 2.5 km x 2.0 km (1.6 x 1.2 mile) island spat out a large plume of volcanic gases and ash in between 13 and 17 km (8 to 10 miles) into the sky. The thick plume was reached the east by a storm in the North Pacific, and astronauts on the ISS, and orbiting satellites, viewed everything occur.

The cloud of ash, with its flattened top, looks like an anvil cloud. An anvil cloud is a kind of cumulonimbus cloud, accountable for thunder and lightning. The top of the ash cloud is flat due to the fact that the density of the cloud has actually matched to the density of the surrounding environment, and the cloud’s stopped increasing. The flat top is called the umbrella area.

In a news release, volcanologist Simon Carn from Michigan Tech commented, “What a magnificent image. It advises me of the timeless Sarychev Peak astronaut picture of an eruption in the Kuriles from about 10 years back. The ring of white puffy clouds at the base of the column may be an indication of ambient air being drawn into the column and the condensation of water vapor. Or it might be an increasing plume from interaction in between lava and seawater due to the fact that Raikoke is a little island and streams most likely got in the water.”

Satellites caught other pictures of the eruption, from various point of views and at a little various times.

The next image was caught with an instrument on NASA’s Terra satellite, called MODIS (Moderate Resolution Imaging Spectroradiometer.) Ash was focused on the western side of the volcano, and was diffused on the east by the action of the storm north of it.

The 3rd image is from the Suomi NPP (National Polar-orbiting Collaboration) satellite. It was caught with the VIIRS (Noticeable Infrared Imaging Radiometer Suite.) It was taken a couple of hours after the others and demonstrates how the wind has actually spread out the ash around after volcanic activity had actually waned.

Japan’s Himawari-8 satellite caught a film of the eruption, and Twitter user Dan Lindsey tweeted the video. It reveals Raikoke appearing in a series of noticable bursts.

The entire eruption was over quite rapidly. A day after Raikoke appeared, which by the method indicates “Hellmouth” in the Ainu language, it was all over. All that was left was a brown smear of ash, retreated and into the storm over the Pacific.
