List of islands created since the 20th century
New islands are islands which have been created recently, whether by means of vulcanism, erosion, glacial retreat, or other mechanisms. One of the most famous new volcanic islands is the small island of Surtsey, located in the Atlantic Ocean south of Iceland. It first emerged from the ocean surface only in 1963. In 1965, it was declared a nature reserve for the study of ecological succession; plants, insects, birds, seals, and other forms of life have since established themselves on the island.
Another noted new island is Anak Krakatau (the so-called "child of Krakatoa", which formed in the flooded caldera of that notorious volcano in Indonesia), which only emerged in 1930. Ample rainforests have grown there, though they are often destroyed by frequent eruptions. A population of many wild animals, including insects, birds, humanborne rats, and even monitor lizards, have also settled there.
Uunartoq Qeqertoq is an island off the east coast of Greenland that appeared to have split from the mainland due to glacial retreat between 2002 and 2005; however, it is believed to have been a true island, with or without glacial covering, for many thousands of years.
In February and March 2009, a vigorous eruption created a new island[1] near Hunga Ha'apai in the Tongan Islands of the southwest Pacific. By the end of the activity, however, the new land mass was connected to Hunga Ha'apai.[2]
On September 24, 2013 a new island emerged off the coast of Gwadar, as a result of a strong earthquake that hit south and southwest Pakistan measuring 7.8 on the Richter scale.[3]
List of recently created islands
This is a list mostly of submarine volcanoes that later became new volcanic islands between the 20th and the 21st century. Aside from Anak Krakatau, only Surtsey and Home Reef are currently islands, and Surtsey is the only one that is expected to survive.
