Volcanic beast lurking beneath the fairytale Greek Island – BBC News in Serbian
At the top of the steep cliffs, Santorini is the world famous tourist destination worth millions. However, below is hiding a great risk of a powerful explosion.
This fairytale Greek island was educated by a strong eruption that took place a long time ago, and she left a huge crater and a shape in the shape of a horseshoe.
Now scientists for the first time explore how much the next great eruption could be dangerous.
The BBC News team spent the day at the British Royal Research Bover of a diskaver (Discovery), looking for answers.
Only a few weeks earlier, almost half of the 11,000 residents of Santorini left the island for precaution, after the series of earthquakes paralyzed everyday life.
It was a cruel reminder to be below the idyllic white villages where Giros is served, accommodation units with jacuzzi and vineyards on fruitful volcanic soil, collide two tectonic plates deep in Earth’s crust.
This expedition is led by Professor Isobel Jeo, expert for very dangerous underwater volcanoes at the British National Oceanography Center.
About two thirds of all volcanoes in the world are underwater, but they are seldom monitored.
« It’s a little like ‘away from your eyes, far from thinking the dangers, as opposed to more familiar volcanoes, » she says on deck, while we look at two engineers down in the water of the car’s water.
These research conducted immediately after a series of earthquakes will help scientists understand what types of seismic disorders can indicate that the immediate of volcanic eruptions.
The last eruption on Santorini took place in 1950. years, but in 2012. a « restless period » was recorded, Isobel says.
Magma was then similar to the Volcan’s interior chambers, and the islands « inflated ».
« Underwater volcanoes are capable of challenging really great, destructive eruptions, » she says.
« If we are accustomed to small eruptions and if there are no dangerous volcanic activities for a long time, then we add into a false sense of security.
« We assume that the next eruption will be the same, but may not, » she explains.
The eruption of the Hunga Tunge volcano in the southern Pacific 2022. produced the largest ever recorded underwater explosion.
That eruption caused Tsunami in the Atlantic Ocean, and the impact waves felt even in the United Kingdom (UK).
Some islands in Tonga, near Vulkan, were so diluted that the inhabitants never returned to them.
Below us, at a depth of 300 meters, there are boiled heat openings.
These cracks in the Earth’s crust convert the seabed into a bright orange world of protruding rocks and clouds of gases.
« We know more about the surface of some planets than about what is down there, » Isobel says.
The robot descends to the sea floor to collect liquid samples, gases and break pieces of rocks.
These openings are hydrothermal, which means that the hot water is spilled from the cracks, and are often formed near the volcano.
It is the reason why isobel and 22 scientists from all over the world have gathered on this ship to implement one-month research.
So far, no one has managed to determine whether the eruption of the volcano becomes more powerful or weakening when sea water mixes with magma in these openings.
« We try to map the hydrothermal system, » Isobel explains.
It’s not like when the folder is made on the mainland.
« We have to peek inside the country, » she says.
The disk storage investigates Calder Santorini and sails towards Columbus, another great volcano in this area, which is located about seven kilometers northeast of the island.
The score of the eruption of these two volcanoes is not expected, but it is only a matter of time when it will happen.
The expedition will make databases and maps of geological hazards for the Greece Civilnr Prottr, explains Professor Paraskevi Nomikou, a member of the Government Crisis team, which met daily during the crisis caused by the earthquake series.
She is born with Santorini, and she grew up with grandparents about earthquakes and eruptions in the past.
It was her volcano was an inspiration to become a geologist.
« This research is extremely important because the local population will provide information on how active, as well as the maps of areas that will be barred from approaches during the eruption, » she says.
Research will determine which parts of the sea floor around Santorini are the most dangerous, the professor is added.
These missions are extremely expensive, and isobel uses every opportunity, and day and night for research, and scientists work in shifts of 12 hours.
John Jamison, Professor at Newfoundlend Memorial University in Canada, shows us pieces of volcanic rocks taken out of hydrothermal openings.
« Don’t touch that, » Professor Jamison warns.
« There’s a lot of Arsen. »
Showing on another sample that seems like a black and orange gun sprinkle, explains: « This is a real mystery, we don’t even know what it’s made up. »
These rocks tell history of liquids, temperatures and materials inside the volcano.
« This geological environment differs from most others. It’s really exciting, » he says.
But the real heart of the expedition is a dark transport container on deck, where four people are looking at the walls placed on the wall.
Using more joysticks that would easily fit into the game console, two engineers manage underwater robot.
Isobel and Paraskewers share an opinion on what could be in a liquid pool that the robot discovered.
They recorded very weak earthquakes in the vicinity of volcanoes, caused by the movement of liquid through the system, due to which cracks are created in rocks.
Isobel lets us audio shot of these cracks they resonate.
The sound is reminiscent of bass in a nightclub that enhances and squeezes.
They determine how liquid moves through the rocks by sending electromagnetic impulses to the country.
Thus a three-dimensional folder that shows how the hydrothermal system is connected to the Chamber filled with Magma, a place where eruption is born.
« We are doing scientific work for people, not for scientists.
« We are here to allow people to feel safe, » Paraskevi says.
The recent series of earthquakes on Santorini clearly showed how much the inhabitants were exposed to seismic threats and how much they depend on tourism.
Me Photographer Eva Rendl welcomes me in her favorite place to record wedding photos.
When Santorini hit the series of earthquakes in February, Eva left the island with her daughter.
« It was really frightening as the earthquakes reinforced, » she said.
Now she’s back, but there’s less work.
« People cancel arrival.
« I usually start recording in April, but I only have the first engagement of this year, » Eva says.
On the main square of the luxury place of IJA on Santorini, the British-Canadian tourist, Jenet says that six of ten passengers from her group canceled the vacation on the island.
He believes that more accurate and more accessory scientific information on the probability of earthquakes and volcanic activities helped people feel more secure when planning travel.
« I’m following the warnings on the Gugle, and the scientist reports and it pumps safety, » she says
However, Santorini will always be a place from dreams.
In Imerovigli we see two who climb curved roofs houses to make a perfect shot.
The couple, who was married only 15 minutes, did not frighten the danger of underwater volcanoes.
They arrived from Latvia.
« We actually wanted to get married next to Volcan, » says that standing next to his young Kristina.
