On 30 March an eruption at Zavodovski was reported and photographed by observers on a fishing vessel, as well as captured by a satellite image. A small ash plume drifted E, producing ashfall on 1/3 to 1/2 of the island. A photo showed bombs being ejected from the crater. One of the world’s largest (if not the largest) penguin colonies resides on the E side of the island and is home to 690,000 breeding pairs. The eruption occurred during molting season in March, when penguins stay ashore. A satellite image captured in May showed an eruption plume coming through the clouds.

The 5-km-wide Zavodovski Island, the northernmost of the South Sandwich Islands, consists of a single basaltic stratovolcano with two parasitic cones on the east side. Mount Curry, the island’s summit, lies west of the center of the island, which is more eroded on that side. Two fissures extend NE from the summit towards the east-flank craters, and a lava platform is located along the eastern coast. Zavodovski is the most frequently visited of the South Sandwich Islands. It was erupting when first seen in 1819 by the explorer Bellingshausen, and the volcano has been reported to be smoking during subsequent visits.
