On the picture, a thin plume of white rises from the volcano on Zavodovski island, the northernmost of the South Sandwich Islands and streams to the northeast.
Further south, a wider white plume can be seen blowing across the Atlantic Ocean. This plume rises from the Mount Michael volcano, which is a young and frequently active strato-volcano located on Saunders Island, near the center of the South Sandwich Island chain. [less]

The satellite picture shows a plume originating from the island's active crater known as Mt Curry, or sometimes also referred to as Mt Asphyxia. It is possible that the plume is created by lava flows in contact with sea water, as it appears to be mainly steam.
Not much else is known about the eruption, because the island is uninhabited and extremely remote and has no monitoring on the island. Most of the information about this eruption will rely on remote sensing (satellite observations). [less]
