Overview
Lateiki, previously known as Metis Shoal, is a submarine volcano midway between the islands of Kao and Late that has produced a series of ephemeral islands since the first confirmed activity in the mid-19th century. An island, perhaps not in eruption, was reported in 1781 and subsequently eroded away. During periods of inactivity following 20th-century eruptions, waves have been observed to break on rocky reefs or sandy banks with depths of 10 m or less.
Dacitic tuff cones formed during the eruptions in 1967 and 1979 were soon eroded beneath the ocean surface. An eruption in 1995 produced an island with a diameter of 280 m and a height of 43 m following growth of a lava dome above the surface.

About the Photo
Waves break over Metis Shoal on 19 February 1968, more than a month after the end of a submarine eruption that began in December 1967 and produced an ephemeral island. Metis Shoal has produced a series of small islands during eruptions observed since the mid-19th century. An eruption in 1995 produced a lava dome that built up to 43 m above sea level.
