Meet the man who has lived alone on this island for 28 years

Mauro Morandi has lived alone on Budelli Island for 28 years.
“What I love the most is the silence,” he says.
“The silence in winter when there isn’t a storm and no one is around, but also the summer silence of sunset.”

Mauro Morandi's failing catamaran was carried to Budelli Island nearly three decades ago by chance.
He never left.

Seventy-eight-year-old Mauro Morandi often walks along the rocky shores of Budelli Island and looks out over the disconsolate sea, feeling dwarfed by the phantom forces that tug and twist the tides.
“We think we are giants that can dominate the Earth, but we’re just mosquitos,” Morandi says.

The Spiaggia Rosa, or Pink Beach, derives its rosy color from microscopic fragments of corals and shells like Miriapora truncata and Miniacina miniace.

In 1989 on a stretch of water between Sardinia and Corsica, with a crippled engine and anchor adrift, Morandi’s catamaran was gripped by these same inexorable forces and carried to the shores of Budelli Island.
When he learned that its caretaker was retiring from his post in two days, Morandi—long disenchanted with society—sold the catamaran and took his place.

Sunlight drenches Morandi's porch, where he likes to dine and read during the summer.

He has lived alone on the island for the past 28 years.

Maddalena Archipelago National Park is comprised of seven islands, and Budelli is considered the most beautiful among them for its Spiaggia Rosa, or Pink Beach.
The rose-colored sand derives its unusual hue from microscopic fragments of corals and shells, which have been slowly reduced to powder by the relentless shifting of the waves.

Morandi waves to a passing boat from his porch.
Although the beach was closed to tourists in the nineties, visitors can access limited parts of the island.

In the early nineties, Spiaggia Rosa was dubbed a place of “high natural value” by the Italian government.
The beach was closed off to protect its fragile ecosystem, and only certain areas remain accesible to visitors.
The island rapidly went from hosting thousands of tourists per day to a single heartbeat.

In 2016, after a three-year legal battle between a New Zealand businessman and the Italian government for ownership of the land, a court ruled that Budelli belonged to Maddalena National Park.
The same year, the park challenged Morandi’s right to live on the island—and the public responded.
A petition protesting his eviction garnered more than 18,000 signatures, effectively pressuring local politicians to delay his expulsion indefinitely.

Morandi practices tai chi on the beach in the morning, absorbing the sun's rays and inhaling in the salty air.

“I will never leave," Morandi says.
"I hope to die here and be cremated and have my ashes scattered in the wind.”
He believes all life is eventually reunited with the Earth—that we are all part of the same energy.
The Stoics of ancient Greece called this sympatheia, the feeling that the universe is an indivisible, unified living organism endlessly in flux.

Morandi is an avid reader, especially during the winter months.

This conviction in our interconnectedness propels Morandi to remain on the island without compensation.
Every day he collects wayward plastic that washes up on the beach and tangles with the delicate flora and fauna.
Despite his aversion to people, he guards Budelli’s shores with fervor and educates summertime visitors about the ecosystem and how to protect it.

Morandi gathers herbs behind his home.
He has a companion who delivers groceries to the island every two weeks.

“I’m not a botanist or a biologist,” Morandi says.
“Yes, I know names of plants and animals, but my work is much different than this. To be able to care for a plant is a technical task—I try to make people understand [why] the plant needs to live.”

Morandi spends many hours looking at the sea.
He believes Budelli Island is the quintessence of beauty.

Morandi believes that teaching people how to see beauty will save the world from exploitation more effectively than scientific minutiae.
“I would like people to understand that we must try not to look at beauty, but feelbeauty with our eyes closed,” he says.

During the winter, Morandi likes to watch the monstrous sea swells that are created by strong winds.

Winters on Budelli are particularly beautiful.
Morandi endures long stretches of time—upwards of 20 days—without any human contact.
He finds solace in the quiet introspection it affords him, and often sits on the beach with nothing but the operatic sounds of the wind and waves to punctuate the silence.

“I’m sort of in prison here," Morandi says of his seclusion,
"but it’s a prison that I chose for myself.”

Morandi collects juniper logs and shapes them into sculptures.
He sells them to tourists and donates the money to NGOs in countries from Africa to Tibet.
Though he inhabits a small piece of land, he is acutely aware of the world at large

Morandi passes the time with creative pursuits.
He fashions juniper wood into sculptures, finding faces hidden in their nebulous forms.
He reads zealously and meditates on the wisdom of Greek philosophers and literary prodigies.
He takes pictures of the island, marveling at how it changes from hour to hour, season to season.

During all his years on the island, Morandi says he has never gotten sick, a quality he attributes to "good genes."

This is not unusual for people who spend extensive periods of time alone.
Scientists have long posited that solitude generates creativity, as evidenced by scores of artists, poets, and philosophers throughout the ages who produced their greatest works in seclusion from society.

Morandi is silhoutted against the light of the dying sun—his favorite time of day when the world seems to grow quiet.
"We think we’re super-humans and divine creatures, but we’re really nothing in my opinion," he says.
"We must adapt to nature.”

The benefits of solitude may not be universal. “Solitude can be stressful for members of technologically advanced societies who have been trained to believe that aloneness is to be avoided,” explains Pete Suedfeld in Loneliness: A Sourcebook of Current Theory, Research and Therapy. However, there are still cultures around the world in which solitary life remains a venerated tradition.
Buddhist monasticism, for example, encourages spiritual devotion and scholarly pursuit above seeking bodily pleasures.

Morandi says he never feels lonely because he is constantly surrounded by life.

But amidst rapid globalization, humans' ability to experience true solitude is perhaps a thing of the past.
In response to increasing development of the region, an internet company established a Wi-Fi connection on Budelli, connecting Morandi and his beloved piece of paradise to the world through social media.
Embracing this new form of communication is his concession on behalf of a larger purpose—to facilitate a bond between people and nature by exposing them to its beauty.
A bond Morandi hopes will motivate people to care for the withering planet.

 Red Desert ( Il deserto rosso) is a 1964 Italian film directed by Michelangelo Antonioni and starring Monica Vitti with Richard Harris.
The film is about a woman struggling to hide her mental illness from her husband while trying to survive in the modern world of cultural neurosis and existential doubt.
Her relationship with her husband's business associate helps her confront her isolation.
Red desert was Antonioni's first color film, one of the filming location was the little island of Budelli in Sardinia.

“Love is an absolute consequence of beauty and vice versa,” Morandi says.
“When you love a person deeply you see him or her as beautiful, but not because you see them as physically beautiful … you empathize with them, you’ve become a part of her and she’s become a part of you. It’s the same thing with nature.”

Huge landslide triggered rare Greenland mega-tsunami

Tsunami waves hit western Greenland after huge landslide - 01:00 UTC, June 18, 2017. 

From Nature by Quirin Schiermeier

Scientists hope studying last month’s deadly event will improve modelling of rockslides that could become more frequent with climate change.


One of the tallest tsunamis in recorded history — a 100-metre-high wave that devastated a remote settlement in Greenland last month — was caused, unusually, by a massive landslide, researchers report.

Seismologists returning from studying the rare event hope that the data they have collected will improve models of landslide mechanics in glacial areas and provide a better understanding of the associated tsunami risks.
They warn that such events could become more frequent as the climate warms.

The landslide occurred on the evening of 17 June, in the barren Karrat Fjord on the west coast of Greenland.
It caused a sudden surge of seawater that wreaked havoc in the fishing village of Nuugaatsiaq, located on an island within the fjord about 20 kilometres away (see ‘Greenland tsunami’).
The wave washed away eleven houses, and four people are presumed dead.

 The right half of the highlighted area shows the scarred hillside in Greenland’s Karrat Fjord after a landslide fell a kilometer into the water below, causing a tsunami that reached 90 meters.
The left half shows at-risk areas.
The trip was funded by National Science Foundation and the Geotechnical Extreme Events Reconnaissance Association.

The slide was so large that it generated a seismic signal suggestive of a magnitude-4.1 earthquake, confounding initial efforts to identify its cause, says Trine Dahl-Jensen, a seismologist at the Geological Survey of Denmark and Greenland.
But more careful examination indicated no significant tectonic activity just before the landslide.



A research team that visited the site earlier this month found that a large volume of rock had plunged — probably spontaneously — from one of the steep sides of the fjord into the water 1,000 metres below, and shattered chunks of a glacier.
That disturbance pushed water levels up by more than 90 metres along the coastline on the same side as the slide.
And although the tsunami dissipated quickly as it crossed the deep, six-kilometre-wide fjord, it still had enough energy to send water 50 metres up the hillside opposite.
The team also measured an increase in water levels of about 10 metres on shorelines 30 kilometres away.
“Landslide-generated tsunamis are much more locally limited than tsunamis produced by sea quakes, but they can be massively tall and devastating in the vicinity,” says Hermann Fritz, an environmental engineer at the Georgia Institute of Technology in Atlanta who led the research team.

 A deadly tsunami hit a remote region of Greenland, leaving four people presumed dead. Dozens more were injured and 11 homes were washed away.
The area near the small town of Nuugaatsiaq has a population of about 84.
Experts think the tsunami could have been caused by a rare 4.0 magnitude earthquake or possibly by a large landslide in the area that could have tricked sensors into registering a seismic event.

On the rocks

Fritz and his team hope to produce a 3D reconstruction of the Greenland event.

Such information is sorely needed, says Costas Synolakis, a tsunami researcher at the University of Southern California in Los Angeles who was not involved in the Greenland survey.
In cold, glacial regions, rocks and ice are held together on steep rock sides, and rising temperatures could make these slopes unstable and these events more common.

Synolakis says that his team has documented in detail only two landslides near glaciers.
“We need at least ten such events to be able to have some rudimentary confidence in landslide computational models to study future impacts and establish early warning criteria.”

Researchers have noted another potentially imminent landslide in the Karrat Fjord, says Fritz, where a slow trickle of rocks could turn into abrupt slide.
Residents of three villages in the region have been permanently evacuated to the nearby town of Uummannaq.

Fritz adds that the Greenland event is reminiscent of a 1958 tsunami — the tallest ever recorded — in Lituya Bay, Alaska.
A magnitude-8.3 quake triggered a landslide into a narrow fjord and the bay’s shallow water, causing the water to rise 500 metres above the normal tide level (a measure known as run-up).
By comparison, the 2011 quake-triggered tsunami in Japan, which killed more than 16,000 people and caused the Fukushima nuclear disaster, reached only about 40 metres at its maximum height.

And in 2015, a landslide-generated tsunami in the Taan Fjord in Icy Bay, Alaska, caused a 300-metre run-up of water, says Synolakis.
“Earlier, we didn’t really believe such extremes were possible,” he says.
“But with global warming and sea level rise, such landslides are going to be far more common.”

Great white shark encounter

Johan Potgieter has an EXTREMELY close encounter with a Great White Shark off the coast of South Africa.


Film teaser : 47 Metres Down review – shark-cage thriller sinks to the bottom
This film labours unpretentiously in the shadow of Spielberg’s Jaws, before it is almost harpooned by an outrageous final twist

A follow-up to the recent great white shark cage breach accident video showing the whole story in context. It includes the original cage breach footage and an analysis.
Even though the shark gets into the cage, it's not a shark attack.
In the moment this was a horrifying shark encounter but it ended good for both the shark cage diver and the great white shark!

Maps for makers: Representing earth through time


From Europeana Labs by Annapaula Freire de Oliveira

Get making with our favorite world maps


We can hardly imagine our daily lives without the precise location information we have at our fingertips – on the screens of our mobile phones or computers.
The last century is considered to be a golden age of map-making.
It has transformed our everyday lives and knowledge of the world, and the digital revolution continues!

However, before globetrotters could trust digital maps to guide them to faraway places, early explorers had to resort to much simpler representations of the world, often drawing the maps themselves throughout their travels.
If you’re fascinated by maps and their history, join us as we outline how early cartographers represented the world as they knew it.
Check out our selection of freely to reuse world maps below to see how cartographers found different ways to represent their understanding of our planet.

T-O maps

The T-O map represents the physical world as first described by the 7th-century scholar Isidore of Seville.
Below a detail of a 14th century 'T-O' map of the world, with Asia, Europe, and Africa marked.

Mappae Mundi

A mappa mundi is a medieval European map of the world.
Take a look at a reproduction of one of the world's most famous maps, named after the Hereford Cathedral in England.
Typical of many medieval maps, the center of the world is presented as the holy city of Jerusalem.
Earth is depicted as a disk and as land surrounded by seas.



Genoese map

Based on the account of the traveler Niccolo da Conti to Asia, the Genoese map is a 1457 world map that possesses a Genoese flag in its upper northwest corner, along with the coat of arms of the Spinolas, a prominent Genoese mercantile family.

Atlas

An atlas is a collection of maps.
Find below a 16th century map from the Water Atlas of the World representing the proverbial "four winds", one from each of the cardinal points - North, South, East, West.




Next, an atlas containing 32 maps from around the world.
It’s divided in two parts: the first identical to the 1650 edition, the second one is an atlas of the ancient world dedicated to Greece and nearby regions.
