Lombok (population 2,950,105 in 2005) is an island in West Nusa Tenggara province, Indonesia. It is part of the chain of the Lesser Sunda Islands, with the Lombok Strait separating it from Bali to the west and the Alas Strait between it and Sumbawa to the east. It is roughly circular, with a “tail” to the southwest, about 70 km across and a total area of about 4,725 km² (1,825 sq mi). The provincial capital and largest city on the island is Mataram.
The Lombok Strait marks the passage of the biogeographical division between the fauna of the Indomalayan ecozone and the distinctly different fauna of Australasia that is known as the Wallace Line, for Alfred Russel Wallace, who first remarked upon the distinction between these two major biomes.
The island’s topography is dominated by the centrally-located stratovolcano Mount Rinjani, which rises to 3,726 m (12,224 ft), making it the third-highest in Indonesia. The most recent eruption of Rinjani was in May-June, 2009, which was a small oozing eruption of ‘Gunung Baru’ (New Mountain). The volcano, and its crater lake, ‘Segara Anak’ (child of the sea), are protected by a National Park established in 1997. The southern part of the island is a fertile plain where corn, rice, coffee, tobacco, and cotton are grown.
The island’s inhabitants are 85% Sasak whose origins are thought to have migrated from Java in the first millennium BC. Other residents include 10-15% Balinese, with the small remainder being Chinese, Arab, Javanese, and Sumbawanese. Since the Sasak population typically practice Islam, the landscape is punctuated with mosques and minarets. Islamic traditions and holidays influence the Island’s daily activities.
