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.
