Where is it? Atlasov Island, off the coast of Russia's Kamchatka Peninsula [50.84755357, 155.56126752]
What's in the photo? The summit of Alaid volcano peeking above a thick layer of low-lying clouds
Who took the photo? An unnamed astronaut on board the International Space Station
When was it taken? Aug. 2, 2019
This eye-catching astronaut photo shows a towering, highly active Russian volcano poking its head above a thick bank of swirling clouds over the Kuril Islands.
The lofty peak is located on Atlasov Island, the northernmost of the Kuril Islands — a chain of roughly 50 largely uninhabited volcanic landmasses stretching along a fault line that runs between Russia and Japan in the Sea of Okhotsk. Altasov lies 40 miles (65 kilometers) off Russia's Kamchatka Peninsula, which is also renowned for its volcanic activity.
The island consists mainly of a single, massive volcano, called Alaid, which is known for its near-perfect cone shape. Alaid reaches up to 7,497 feet (2,285 meters) above sea level, making it the tallest peak in the Kuril Islands.
Alaid has erupted at least nine times in the past 50 years, including a major outburst in April 1981 that ejected a 1,250-mile-long (2,000 km) plume of thick smoke and ash into the atmosphere, according to the Smithsonian Institution's Global Volcanism Program.
Its most recent eruption occurred between September and November 2022, when a river of lava flowed down its flank (see below). During this outburst, the volcano also spit out smoke and ash that was spotted from space alongside another eruption plume coming from the nearby island Paramushir.
Alaid last erupted in November 2022 and unleashed a scorching lava flow down its snow-covered slopes. This photo also shows what Atlasov Island looks like when it is not obscured by clouds.

The summit of Alaid, crowned by a roughly mile-wide (1.6 km) caldera, is also obscured by clouds. (The volcano was not erupting when the photo was taken.)
Farther down the volcano's flanks are a series of snow-filled gullies carved out by lava flows from previous eruptions. Eagle-eyed viewers may also be able to spot some parasitic cones — small openings where lava burst through in the past — around the edge of the cloud layer, according to NASA's Earth Observatory.
The area surrounding a cluster of parasitic cones on the volcano's northwest flank (top right in the photo) is devoid of vegetation — a result of another major eruption in 1972, which scoured the surrounding landscape with hot ash. A 2009 study revealed fresh signs of recovery in the affected area, but noted that it could take hundreds of years for vegetation to return to pre-eruption levels.
The clouds are not the only thing the island rises above. Alaid is essentially the summit of a much larger underwater volcano that lies beneath the Sea of Okhotsk. The rest of the island has grown around the exposed cone as lava flows have reached sea level and solidified. Millions of years ago, this larger volcano was likely connected to the Kamchatka Peninsula via a land bridge that has since been submerged.
In 1981, a major eruption caused Alaid to unleash a massive plume of smoke and ash that reached up to 1,250 miles long.

And in 2022, the Landsat 8 satellite also spotted the iconic summit of Mount Vesuvius peeking through a gap in the clouds over Italy, just like Alaid.
