Gaua
Gaua (formerly known as Santa Maria Island) is the largest and second most populous of the Banks Islands in Torba Province of northern Vanuatu. It covers 342 km².
History
Gaua was first sighted by Europeans during the Spanish expedition of Pedro Fernández de Quirós, from 25 to 29 April 1606. The island’s name was then charted as Santa María.
Physical geography
It has rugged terrain, reaching up to Mount Gharat (797 m), the peak of the active stratovolcano at the center of the island. The most recent eruption was in 2013. The volcano has a 6 x 9 km caldera, within which lies a crater lake known as Lake Letas, the largest lake in Vanuatu. To the east of the lake is Siri Waterfall (120 m drop).
Population and languages
The island has a population of 2491 (in 2009), with an annual growth rate of 2.0 percent.
This population is scattered in various coastal villages on the western, southern and northeastern sides of the island. The eastern side has a few hamlets with an immigrant population coming mainly from the two smaller islands Merig and Merelava, southeast of Gaua. The largest village is Jolap, on the west coast.
