Many people believe that the islands, like many other geographic features, appeared long before modern history. However, weather conditions, natural phenomena and human activity led to the formation of several islands, most of them in the twentieth century. The most remarkable artificial islands are found in the United Arab Emirates. The islands on this list were formed by erosion, volcanism, glacial retreat or other natural mechanisms. Since the early 1900s, there have been approximately 25 new islets, but this list covers those formed between 2013 and 2017.
Shelly Island (2017)
Shelly Sand Island is a barrier island that began to form around April 2017 along the tip of the outer tip of the North Carolina outer shores. Originally, the island was one kilometer long and 500 feet wide, but greatly reduced after Hurricane Maria. The Atlantic Cemetery surrounds Shelly Island, located near Hatteras Island. Shelly is under the jurisdiction of Dare County, North Carolina, although, if it merges with Hatteras Island, it will fall under federal jurisdiction. Shelly, nicknamed because of the huge amounts of seashells that line its shores, formed quickly, possibly through high tide or stormy waters (or both) that added sediment to the area.
Hunga Tonga-Hunga Haʻapai (2009, 2014-2015)
Hunga Tonga-Hunga Haʻapai are two adjacent volcanic islands located approximately nineteen miles south-southeast of Falcon Island in Tonga. The two islands are located in the active volcanic arc of the Tonga-Kermadec Islands, 62 miles directly above an active seismic zone and, therefore, the magma from different tectonic plates melted the rocks. These tectonic plates are the Indo-Australian plate and the Pacific plate. The two islets total an area of ​​0.40 and form in 1616, although significant additions took place in 2009, then in 2014 and 2015. The deposits of Tombolo and sand have since united the two islands, although researchers believe that this attachment could be temporary or permanent due to the active volcanic nature of the region.
Jadid Island and the Zubair group (2013)
Also known as the Al Zubair group or Zubayr group, Zubair consists of ten volcanic islands located at the top of an underlying volcano in the Red Sea territory of Yemen. Throughout history, the islands have formed due to explosive and effusive eruptions followed by periods of inactivity that have led to marine erosion. Several underwater eruptions occurred in 2011, 2012 and 2013, leaving vents through which water penetrated and created Surtseyan activities which released ash plume and vapor into the air. The 2013 eruption occurred less than 328 feet below the ground and formed the new island of Jadid.
Nishi-no-shima Island (1973-74, 2013-15)
The volcanic island of Nishi-no-shima (Rosario Island) is located 584 southeast of Tokyo and is part of the arc of the volcanic islands. Before 1974, the island was a small point of underwater caldera, but it grew as a result of volcanic cone eruptions 1974, 2013 and 2015 from a height of about 466, a total area of ​​667.18 small island south-east of the original island. In late 2016, Japan announced that the landing on certain parts of the island was safe and finally, in February, 2017, the country declared that there were no signs of an eruption and that the Island was safe in April. . Biologists believe that wildlife will soon colonize the island.
How other forms of new islands
Volcanism is responsible for the formation of the most recent islands, but other natural forces have led to the formation of other islands. For example, the island of Yaya in the Laptev Sea, Russia, formed from melted ice. In 2013, an earthquake led to the formation of Zalzala Koh ( Earthquake ) or Zalzala Jazeera ( Island Earthquake) off the port of Gwadar in Pakistan. This island however disappeared at the end of 2016. The movement of the glaciers and the collapse also detached the island Uunartoq Qeqertaq from the continent of Liverpool Land between 2002 and 2005. The island of Tigres, the largest island of Angola , located in the Atlantic Ocean, was originally a peninsula and became an island,
