Sarychev Peak Eruption, Kuril Islands

A fortuitous orbit of the International Space Station allowed the astronauts this striking view of Sarychev Volcano (Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009. Sarychev Peak is one of the most active volcanoes in the Kuril Island chain, and it is located on the northwestern end of Matua Island. Prior to June 12, the last explosive eruption occurred in 1989, with eruptions in 1986, 1976, 1954, and 1946 also producing lava flows. Ash from the multi-day eruption has been detected 2,407 kilometers east-southeast and 926 kilometers west-northwest of the volcano, and commercial airline flights are being diverted away from the region to minimize the danger of engine failures from ash intake.

This detailed astronaut photograph is exciting to volcanologists because it captures several phenomena that occur during the earliest stages of an explosive volcanic eruption. The main column is one of a series of plumes that rose above Matua Island on June 12. The plume appears to be a combination of brown ash and white steam. The vigorously rising plume gives the steam a bubble-like appearance; the surrounding atmosphere has been shoved up by the shock wave of the eruption. The smooth white cloud on top may be water condensation that resulted from rapid rising and cooling of the air mass above the ash column. This cloud is probably a transient feature: the eruption plume is starting to punch through. The structure also indicates that little to no shearing wind was present at the time to disrupt the plume. (Satellite images acquired 2-3 days after the start of activity illustrate the effect of shearing winds on the spread of the ash plumes across the Pacific Ocean.)

By contrast, a cloud of denser, gray ash—probably a pyroclastic flow—appears to be hugging the ground, descending from the volcano summit. The rising eruption plume casts a shadow to the northwest of the island (image top). Brown ash at a lower altitude of the atmosphere spreads out above the ground at image lower left. Low-level stratus clouds approach Matua Island from the east, wrapping around the lower slopes of the volcano. Only about 1.5 kilometers of the coastline of Matua Island (image lower center) are visible beneath the clouds and ash.

Those astronauts always get the best seat in the house

When the earth belches millions of tons of CO2 into the atmosphere, it's natural, it's ok.

When man does it it's baaaaddd!

[yamahonkawazuki]

@Dajida dont forget man is entirely responsible. lol

[intigfx]

Just like every Moon video will have its Moon landing denialists, it seems every volcano video will have its GW denialists. Fucking idiots are everywhere.

How high did the ash plume go? Looks like it's way above the cloud layer, but that could be a forced perspective/opticle illusion.

[enjoybrad]

@Picard578 Or, the system is going out of balance because the Earths magnetic poles are shifting. Either way, we're all screwed. Get used to it, and enjoy your life while you can. All of you!

@SirReal121 good, thank you

[gwgbass]

@Dajida

Just wait, the government will try and find a way to tax it.

Somebody sqeezed chuck norris' zit
