Medan is the capital of the North Sumatra province in Indonesia. Located on the northern coast, Medan is the fourth largest city in Indonesia (behind Jakarta, Surabaya, and Bandung), and the largest Indonesian city outside Java. The city is bordered by the Deli Serdang Regency to the east, south and west, and the Strait of Malacca to the north. It is close to the volcano Sinabung, which erupted in August 2010 after a 400 year dormant state.
