Question

Answer 1

Off the coast of Iceland
Surtsey was formed in a volcanic eruption which began 130 m (426 ft) below sea level, reached the surface on 14 November 1963 and continued to 5 June 1967, when it measured 2.7 sq km (1 sq mile). It has subsequently eroded to less than 1.4 sq km (0.54 sq miles).
