[2] Also part of the sub-district is the Sikakap Strait between North and South Pagai, a designated Regional Marine Conservation Area.

[3] The Strait, an area of 3,960 hectares (9,800 acres), has a coastal length of 19.79 kilometres (12.30 mi) and is a major contributor to West Sumatra's fishing industry.

[8] There is a hospital and a church in the village,[9][10] as well as a harbor[11] (the main transport hub in the Mentawai islands[12]) and a district police station.

[19] Relief agencies and a government command post were based there during the crisis,[20] as it is the largest village on Sipura and Pagai.

[24] A month later, displaced people were still living in tents in Sikakap, leading the government to announce the construction of 16 homes there,[25] as 17 had been heavily damaged.
