Gough Island was inscribed as a World Heritage Site in 1995. In 2004 the site was extended. The marine zone of Gough Island was extended from 3 to 12 miles and Inaccessible Island was included with the surrounding marine zone extending out to 12 miles. The site was renamed Gough and Inaccessible Islands.
The selection criteria for the site do not include its geomorphic interest. However, there has been ongoing discussion of including Gough and Inaccessible Islands in a possible "serial trans-boundary nomination" for the Mid-Atlantic Ridge, which would include other volcanic sites in the Atlantic.
