Residents of a fishing town in southwestern Iceland left their homes Saturday after increasing concern about a potential volcanic eruption caused civil defense authorities to declare a state of emergency in the region.
Police decided to evacuate Grindavik after recent seismic activity in the area moved south toward the town and monitoring indicated that a corridor of magma, or semi-molten rock, now extends under the community, Iceland’s Meteorological Office said. The town of 3,400 is on the Reykjanes Peninsula, about 50 kilometers southwest of the capital, Reykjavik.
“At this stage, it is not possible to determine exactly whether and where magma might reach the surface,” The Associated Press quoted the Meteorological Office as saying.
Authorities also raised their aviation alert to orange, indicating an increased risk of a volcanic eruption. Volcanic eruptions pose a serious hazard to aviation because they can spew highly abrasive ash high into the atmosphere, where it can cause jet engines to fail, damage flight control systems and reduce visibility.
A major eruption in Iceland in 2010 caused widespread disruption to air travel between Europe and North America, costing airlines an estimated $3 billion as they canceled more than 100,000 flights.
The evacuation comes after the region was shaken by hundreds of small earthquakes every day for more than two weeks as scientists monitor a buildup of magma some 5 kilometers underground.
Concern about a possible eruption increased in the early hours of Thursday when a magnitude 4.8 earthquake hit the area, forcing the internationally known Blue Lagoon geothermal resort to close temporarily.
The seismic activity started in an area north of Grindavik where there is a network of 2,000-year-old craters, geology professor Pall Einarrson, told Iceland’s RUV. The magma corridor is about 10 kilometers long and spreading, he said.



Italy Oyster Farmers Dream of Pearls from Warming Mediterranean

Pearls may soon be cultivated in European seas for the first time ever, as Italian oyster farmers seek to exploit an unexpected opportunity offered by the rapidly warming Mediterranean.

In late 2023, the first specimens of Pinctada radiata, a pearl oyster native to the Red Sea, were spotted in the Gulf of Poets, a popular tourist area around 100 kilometers (62 miles) from Genoa on Italy's north-western coast.

Less than a year later, they are proliferating in what have always been some of the Mediterranean's coldest waters, more normally associated with other types of oyster used for food rather than jewellery.

"We are looking into the possibility of producing cultivated pearls here," said Paolo Varrella, the head of a cooperative that has been breeding food oysters in the area since 2011.

The group has already made contact with pearl oyster farmers in Mexico to get tips on production techniques, Varrella said.

"The Pinctada radiata has been reported in the Ionian Sea around the island of Sicily since the 1970s, but only in the last decade has it moved north" to the cooler Tyrrhenian and Ligurian seas that lap the western Italian mainland, said Salvatore Giacobbe, professor of ecology at the University of Messina.

It is the latest in a succession of alien warm-water species to enter the Mediterranean as it heats up due to climate change.

Manuela Falautano, a scientist at the Italian environmental research and protection institute ISPRA, said this trend had seen "an exponential increase" in the last decade.

Some of these species are aggressive and disrupt delicate ecosystems. In a few cases, such the spotted puffer fish and the scorpion fish, they are also dangerous to humans.

The 2.5 million square kilometer (970,000 square mile) expanse of water that separates southern Europe from Africa and the Middle East is heating up faster than the average of the world's seas, Falautano said.

BIG MONEY

Pearl production, more readily associated with Polynesian atolls than the northern Mediterranean, has an annual global turnover of 11 billion dollars, and Italian oyster farmers are keen to cash in.

Adriano Genisi, a pearl importer for more than 30 years, said the Radiata may produce gems similar to Japan's renowned "Akoya" pearls which have a diameter of 5-9 millimeters and a white color with shades of grey, pink and green.

If all goes well the first pearls could be harvested in about a year, he said.

The rising temperature of the Mediterranean is also blamed for an increase in violent storms such as the one that sank the luxury yacht of British tech entrepreneur Mike Lynch off Sicily last month, killing six passengers and the boat's cook.

Franco Reseghetti, a researcher at Italy's National Institute for Geophysics and Vulcanology, said measurements taken in the Tyrrhenian in December at depths of between 300 and 800 meters showed the highest temperatures since 2013, and he expected to see a further increase this year.

"The huge amount of energy behind this heating can act as a fuel for devastating atmospheric phenomena" such as the violent storm which appeared to have sunk the yacht off Sicily, Reseghetti said.
