Dust Plumes Off Socotra Island, Yemen12.4N 53.8E
Dust blows over the Indian Ocean near the Gulf of Aden, between Somalia (below) and Yemen (above). Two thick plumes blow towards the northeast, off the island of Socotra (center right).
The island, which is part of Yemen, lies some 240 kilometres (150 mi) east of the Horn of Africa and 380 kilometres (240 mi) south of the Arabian Peninsula. It has three geographical terrains: the narrow coastal plains, a limestone plateau permeated with karstic caves, and the Haghier Mountains. The mountains rise to 5,000 feet (1,500 m). The island is a little over 80 miles (130 km) long east to west and typically 18–22 miles (29–35 km) north to south.
