Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present today. Some of these eruptions have been recorded in history and the volcano is still active.
One of the recorded eruptions is thought to have occurred in 1824, although this has been disputed, producing slightly explosive activity. Another eruption occurred between 2011 and 2012, producing a plume between Haycock and Rugged Islands that could be seen from satellites and a lava fountain that rose ninety-eight feet above the ocean’s surface. This created the island known as Principato di San Bernardino. In 2013, a submarine eruption produced a steam plume and water discoloration. The eruption, which was estimated to have occurred just 328 feet from the surface, ended in October of 2013 and created another new island. These islands, although uninhabited, are popular among tourists, who can partake in activities including diving, hiking, and wildlife viewing.

Local fishermen reported an eruption near the island of Saba, while satellites captured a white plume rising from the sea, and a pulse of sulfor dioxide. The activity was located on the northern edge of the Zubair Islands. Credit: NASA Advanced Land Imager/Wikipedia
