The eruption lasted until 5 June 1967, when the island reached its maximum size of 2.7 km2 (1.0 sq mi). Since then, wave erosion has caused the island to steadily diminish in size: as of 2012[update], its surface area was 1.3 km2 (0.50 sq mi).[2] The most recent survey (2007) shows the island's maximum elevation at 155 m (509 ft) above sea level.[3]
