Islands are disappearing worldwide. But from the volcano Kilauea in Hawaii, a new one has formed.



A small new world has materialized on the shores of the Big Island of Hawaii. The 20 x 30 foot area is a geological Tabula Rasa, untouched and unlike anywhere else on earth.

The island appeared for the first time on Thursday from the lava that sprang from a new rift on Kilauea volcano in May. according to the United States Geological Survey. The agency said that underwater pressure forced the lava flowing from the ventilation to the surface. A Hawaiian volcano observatory crew noticed the crowd during a Friday morning flight.

Kilauea, one of the world's most active volcanoes, has been virtually uninterrupted over the last 35 years and has been very intense in recent months. In June molten rock smothered an area called Vacationland. And on Monday, a basketball-sized lava bomb smashed the roof of an excursion boat and injured more than 20 people

The cascade of eruptions and earthquakes has shown increased volcanic activity in recent months. Two Vents ̵

"Now we have a series of daily explosions at the summit, every single day – Boom – Boom – It's a progressive collapse of the summit."

The lava that fed these vents escaped, Garcia said, and now feeds a vent in the Leilani site near the southeastern tip of Hawaii. New cracks in the earth release streams of molten rock, leading to evacuations, as the fire engulfs homes in rural areas where the property is relatively cheap, but life is dangerous. After the Hawaii Tribune-Herald, about 700 houses have been destroyed since May.

But property damage is not the only consequence of eruptions. Volcanic activity can drive the structural transformation of oceanic islands such as Hawaii and Tahiti, Garcia said.

Around the world, other causes of island formation include erosion and glacier retreat. Shelly Island, a crescent-shaped sandbank, began to form in the Outer Banks of North Carolina in the spring of 2017, but disappeared in early 2018. Uunartoq Qeqertaq, Greenland for "The Very Hot Island", was separated from mainland Greenland in 2005 as a result of the retreat of the ice shelves

Whether or not the tiny new mass will survive out of the coat of Hawaii is an open question, scientists said. Crucial factors are the duration of new eruptions and the type of surface that takes shape – hard lava that is likely to last long enough to settle plants and animals, or ash that is more prone to erosion.

"I think we can expect the unexpected," Garcia said. "If the latest eruption were to stop in the near future, the island would dry up, but if the eruption progresses and the bay fills, it is likely that the coast could dodge to this island and you could have an extended coastline." [19659010] If the island survives, it would be an opportunity to study how living in a living new territory – a blank slate that would be a chance for earth scientists to ask new questions about the ground that we occupy or not. "How does life get to new places and evolve?" Garcia said, envisioning the research opportunities that could await him. "It's a wonderful mystery, and we're still challenged to fully appreciate it."

He tempered his expectations: "It may not survive long enough to support life and change it – we've had so much in Japan – a volcano is erupting, forming a new island, and coming soon He's gone. "

New islands are becoming scarcer in a time of rising sea levels, said Professor Alastair Bonnett of Social Geography at Newcastle University in the UK and the author of" Off the Map: Lost Spaces, Invisible Cities, Forgotten Islands, Wild Places and what they tell us about the world. "

Today islands make headlines most often because they disappear, they do not come alive. The phenomenon of disappearing islands is so pronounced that it forms the basis of a special tourism field. The website Jetsetter advertises "8 Islands to Visit Now before they disappear". Mother Jones asks if Tuvalu, a Polynesian island nation of coral atolls reminiscent of Gauguin's painting of the South Seas, "becomes a modern Atlantis?"

There are no new islands to replace the vanished islands, but some of the new arrivals are artificial, such as the island of Deira off the coast of Dubai or a fleet of man-made islands on which Chinese military equipment is stationed in southern China Sea.

Far from man-made, Hawaii's new island surprised everyone. It does not even have a name. And Hawaii officials said this week that there was evidence that the island was already becoming a peninsula and joining the main island, according to Hawaii News Now.

Fissure 8 is the tentative name for the vent that lava forming launches the new landmass. A member of the Hawaii County Council has this month submitted a resolution requesting the State Board on Geographic Names to consult with church members who have a direct traditional, cultural and family connection to the Puna district "

Bonnett Said that new volcanic islands are remarkable, not only because they are spectacular, but also because they are not commonplace.About three quarters of the world's molten magma comes from the sea, but it takes a lot to build an island . "

" New islands carry a kind of hope and a fresh start, "said Bonnett. "New islands disturb our sense of orderly geography, so they fascinate us too, little ones, we can not believe that land can be created right in front of our eyes – it feels like some kind of magic, we stick to the idea – in spite of everything Contrary proof – that our planet is an immobile lump. "

It is" no coincidence ", Thomas Bonnett said, that Thomas More chose an island as the setting for his sociopolitical satire of 1516" Utopia ", which coined the term for a place, where everything is perfect. Neologism refers to the Greek ou-topos, meaning "no place or" nowhere ", and eu-topos, meaning" good place. "It refers to an unfinished, ideal project – perhaps unattainable, but perhaps not.
