The Birth of a New Island, Hunga Tonga-Hunga Ha’apai, Tonga
In late December 2014, a submarine volcano in the South Pacific Kingdom of Tonga erupted, sending a violent stream of steam, ash and rock into the air. The ash plumes rose as high as 9 kilometers into the sky, diverting flights. When the ash finally settled in January 2015, a newborn island with a 120-meter summit nestled between two older islands – visible to satellites in space.
The newly formed Tongan island, unofficially known as Hunga Tonga-Hunga Ha’apai after its neighbors, was initially projected to last a few months. Now it has a 6- to 30-year lease on life, according to a new NASA study.
