The Mysterious island:

The M ysterious island

How are islands formed ? :

How are islands formed ? Islands are formed when a volcanic eruption happens over a water body and it releases lava and several other substances from the crater. In due course of time the lava cools down and it turns into a solid. The accumulation of all these solids is what makes an island. The process takes millions of years.

As u know the islands are emerging again and again so here is a list of islands which have recently emerged :

If the magma breaks through the crust, a volcano forms. Hot spot volcanoes on the ocean floor can become islands. This is how the Hawaiian islands were formed A volcano forms above a hot spot when magma erupts through the crust and reaches the surface. A hot spot is a place where material rises from deep within the mantle. The material forms magma.

New islands are islands which have been created recently, whether by means of volcanism, erosion, glacial retreat, or other mechanisms. :

New islands  are islands which have been created recently, whether by means of  volcanism,   erosion,  glacial retreat, or other mechanisms . One of the most famous new volcanic islands is the small island of Surtsey, located in the Atlantic Oceans 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 .

Surtsey  is a volcanic island off the southern coast of Iceland. At 63.303°N 20.6047°W. Surtsey is the southernmost point of Iceland. It was formed in a volcanic eruption which began 130 meters (426 ft) below sea level, and reached the surface on 14 November 1963. The eruption lasted until 5 June 1967, when the island reached its maximum size of 2.7 km2(1.0 sq mi). Since then, wind and wave erosion have caused the island to steadily diminish in size: as of 2002, its surface area was 1.4 km2:

Verbeek, in his report on the eruption, predicted that any new activity would manifest itself in the region which had been between Perboewatan and Danan. This prediction came true on 29 December 1927, when a submarine lava dome in the area of Perboewatan showed evidence of eruptions (an earlier event in the same area had been reported in June 1927). A new island volcano rose above the waterline a few days later. The eruptions were initially of pumice and ash, and that island and the two islands that followed were quickly eroded away by the sea. Eventually a fourth island named Anak Krakatau broke water in August 1930 and produced lava flows faster than the waves could erode them. These new islands are of considerable interest to volcanologists, and have been the subject of extensive study.:

Al Zubair Group or Zubayr Group is a group of 10 major volcanic islands, on top of an underlying shield volcano in the Red Sea, which reach a height of 191 M above sea level. The volcano has continued to erupt in historic times. The islands currently belong to Yemen.:

The volcano has continued to erupt in historic times. The islands currently belong to  Yemen . The largest island is Zubair, which is one of the younger islands. Other young islands are Centre Peak, Saba, Haycock, and Saddle. Saddle Island has had eruptions in historic times.

Nishinoshima  is a town located on the island of Nishinoshima, in Oki District, Shimane Prefecture, Japan.:

Nishinoshima   is a town located on the island of Nishinoshima, in Oki District, Shimane Prefecture,  Japan. After the Meiji restoration, the Oki Islands became part of Tottori Prefecture in 1871, but were transferred to Shimane Prefecture in 1881.The island was divided between Urago Village in the west and Kuroki Village in the east in 1904. The two municipalities were divided by a canal in 1915, which cut the island into two parts. Urago became a town in November 1946 and merged with Kuroki in 1957 to form Nishinoshima Town. The two portions of the island were joined together by a bridge in 2005 .

Zalzala Koh or Zalzala Jazeera  is a small island off the coast of the port city of Gwadar, Balochistan, Pakistan which appeared on 24 September 2013 following an earthquake. As predicted by many geologists, the island has started to resubmerge, with satellite images indicating the island has sunk 10 feet into the sea since its initial appearance.:

As predicted by many geologists, the island has started to resubmerge, with satellite images indicating the island has sunk 10 feet into the sea since its initial appearance . Zalzala Koh may be a mud volcano , located in the Arabian Sea offshore of Gwadar in Balochistan, Pakistan. It rose out of the water during a 7.7-magnitude earthquake that struck the same province on 24 September 2013. Ali Rashid Tabriz, the head of Pakistan’s National Institute of Oceanography, said that the surfacing of the island had been caused by an emission of methane gas on the seabed.

Uunartoq Qeqertaq, Greenlandic for "The Warming Island", is an island, that was only acknowledged as such in September 2005, by an American explorer Dennis Schmitt, off the east central coast of Greenland, 550 km (340 mi) north of the Arctic Circle. It was attached to the mainland of Liverpool Land by glacial ice even in 2002, when the ice shelves began retreating rapidly in this area, so that by 2005 it was no longer attached to the mainland. Members of the scientific community believe this newly discovered island is a direct result of global warming. The island has three large peninsulas, and thus resembles the letter W.:

Kavachi is one of the most active submarine volcanoes in the south-west Pacific Ocean. Located south of Vangunu Island in the Solomon Islands, it is named after a sea god of the New Georgia Group islanders. The volcano has become emergent and then been eroded back into the sea at least eight times since its first recorded eruption in 1939.:
