'High' alert, wildfire threats after Iceland's Sundhnukur volcano erupts
"Seismic activity has decreased significantly and only a few small earthquakes are now measured per hour," according to Iceland's meteorological agency in a translated afternoon update.
The volcano alert level, it added, remained at its "highest level" as a possibility of wildfires remains. But it said ongoing threats of polluted air from the toxic substances was minimally detected and "not reflected in current pollution forecasts."
There have been no reports of injuries.
For its 12th time in four years, Sundhnukur in the Reykjanes Peninsula on the west southern tip of Iceland spewed smoke and volcanic lava in the air Wednesday morning in its latest activity after centuries of silence until 2021.
Tourists, families, hotel guests and the public in nearby resort towns were evacuated as a precaution in Grindavík, Blue Lagoon resort and other areas. However, despite this, no flight disruptions were reported at nearby Keflavík airport.
Initial reports indicated that liquid hot magma created a fissure in the Earth's crust around 2,296 feet and 3,280 feet long after an "intense earthquake swarm."
The GPS and deformation data originally suggested a minor eruption by comparison. A smaller crater also opened west of Fagradalsfjall, estimated to be roughly 1,640 feet long.
However, the afternoon update noted the eruption fissure "lengthened and extends further north than previous eruption fissures" since December 2003.
The agency said at the time that lava flow was concentrated and did "not threaten any infrastructure at this time."
High levels of gas pollution were reported by authorities in the municipality of Reykjanesbær after wind carried it but later decreased in toxicity. In its afternoon update, lava was reported flowing northeast from its source covering a large area on Kálffellsheiði and towards Svartsengi.
Since 2020, the Reykjanes Peninsula in southwestern Iceland has produced multiple volcanic eruptions and was active all last year in January through to November after earthquakes activated systems.
The town of Grindavík once housed around 4,000 Icelanders but was evacuated late last year and has reportedly largely remained a ghost town over safety due to ongoing volcanic risk as Icelandic authorities warned tourists to stay away from the area.
Iceland's Sundhnukur volcano was active as recently as early February and May of last year.

Overcrowded Vatican And Other Micro Countries Top Overtourism Report
From monuments and sites such as the Louvre Museum in Paris and the Trevi Fountain in Rome, islands including Santorini and the main Canary islands, to cities large and small like Spain's Barcelona, Italy's Venice, Croatia's Dubrovnik and Belgium's Bruges, the lists of European destinations impacted by overtourism grow every year. Along with that growth are massive protests of increasingly frustrated and angry residents tired of record crowds,, noise, overwhelmed services, impossible housing costs, traffic congestion that threat their way of life. Posters inviting visitors to 'Go Home' and even cases of physical attacks against tourists like in Barcelona and Valencia this summer where protesters shot water guns to unsuspecting tourists are not rare. Anti-tourism movements are starting to have an effect on local elections. The fear of an "Overtourism Crisis" in Europe with the surging in the numbers of travellers coming to the old continent this summer is real and forcing governments to address the environmental, social and economic pressures it is creating. During the first quarter of 2025, there were 452.4 million overnight stays in tourist accommodations across the EU, according a European Commission's Eurostat analysis. Last year, 747 million international travellers visited the continent, far outnumbering any other region in the world, according to the U.N.'s World Tourism Barometer. Some countries carry heavier loads than others. France, the biggest international destination, last year received 100 million international visitors, while second-place Spain received almost 94 million — nearly double its own population. Visiting many of the most popular sites in Europe has become a physical ordeal where after long lines people are pushed through by the masses trying to take selfies. 'Europe, often dubbed the world's museum, is grappling with an unprecedented surge in tourism, transforming its picturesque streets into crowded thoroughfares and sparking widespread 'overtourism concerns,' writes The Independent. 'The continent's record-breaking visitor numbers are now straining local resources and sparking a backlash from residents as the familiar sight of suitcases rattling on cobblestones and selfie-snappers jostling for position has become a symbol of the strain." Cruise ships, bringing thousands of visitors to locations already overwhelmed by overtourism like Venice, the Canary and Balearic islands, Santorini and other small Greece islands, leave a significant ecological impact while contribute little to the local economy. Foreign visitors accounted for approximately 45.6% of all overnight stays in the first 3 months of 2025, as per the Eurostat report. What is new is the large differences among EU countries, with the smallest ones like Malta (91.2%), Cyprus (85.7%) and Luxembourg (80.4%) getting the biggest share of foreign overnight stays, above the "usual suspects" like Spain, France and Italy. The first places of the top most overcrowded tourist destinations in the world — measured by the number of visitors (taken from tourism figures from national tourist boards and reports), outnumbering the local population by a lot ,- in a new ranking by Go2Africa highlighting the growing global trend. Although, as explained by The Mirror in an article titled 'Do not travel zones where tourists overwhelm locals', 'the ratio of visitors to locals does not tell the complete story of a destination and its relationship with tourism, it gives a good indication of how reliant a place's economy is on tourism and how busy it's likely to feel during peak season.' Vatican City Tops Overtourism Ranking In # 1 with the most disproportionate tourist per local ratio is Vatican City, the world's smallest country in area and population. A sovereign city-state located within Rome it is just 0.44 square kmts. in size and a place of pilgrimage and cultural significance for many people around the world. With just 882 residents the Vatican welcomes a staggering 6.8 million tourists a year which equates to 7,710 visitors for every local. 'Every day thousands of visitors are literally pushed through this Vatican cash machine by the museum's guardians,' writes a visitor in Tripadvisor about the experience at the Vatican Museum. 'Practically no chance to quietly admire the various masterpieces.' Statistics from last May show that the number of visitors at the Vatican can reach 25,000 per day with massive ticket lines often snaking around the walls. That's more than 1/2 million visitors per month. In second and third place are also other European micro-countries. Principality Of Andorra Second In The List The principality of Andorra a land-locked small country of 468 square kms, 2 and ½ times the size of Washington D.C, located between France and Spain takes second place. With a population of over 85,000 people -by a 2023 census-, this small European country best known for its luxury ski resorts and tax-free shopping, receives around 9.6 million tourists per year. This equates to a ratio of 118 tourists per resident. The status of the tiny principality as a tax haven and the fact that it is almost entirely geared towards tourism, contribute to its outsized appeal. Nestled in Pyrenees, Andorra also offers stunning landscapes with peaks over 2,000 metres high, deep valleys and winding rivers. Tiny San Marino And Overtourism The third country in the list, where visitors outnumber the local population is another mountainous landlocked microstate in Southern Europe: San Marino. Surrounded in all sides Italy and founded in 301 AD, it is the world's oldest surviving republic, maintaining its independence for over 1,700 years. A UNESCO World Heritage Site it boasts three imposing fortresses on surrounding towering peaks. The capital, also called San Marino is located in the slopes of Monte Titano and its known for its medieval walled old town and narrow cobblestone streets. Visitors are drawn to the landscape, cuisine and architectural sights. Over 60 kilometres squared, it's the third smallest territory in Europe and the fifth smallest in the world. With only 33,600 residents San Marino attracts 2 million tourists per year which equates to a ratio of 60 tourists per local. At the same time that San Marino appears among the destinations with locals being outnumbered by visitors, it is frequently mentioned in rankings of the l'east visited countries in Europe.' Has Monaco An Overtourism Problem? Another principality, Monaco, a sovereign microstate on the Mediterranean Sea's French Riviera, not far from the Italian region of Liguria, attracts luxury travelers to its famous casinos, yachts, and Mediterranean coastline and the city-state is often packed with visitors. Monaco gets around 340,000 tourists per year. If, according to the local Monaco Voice, 'Monaco seems to have avoided the pitfalls of mass tourism,' it still appears in #8 of the list of places where visitors outnumber the local population. The principality occupies an area of 2.08 square kms, making it the second-smallest sovereign state in the world, after Vatican City. Its population of 39,000 makes it the most densely populated sovereign state. Only around 10,000 residents are Monégasque nationals. Monaco also has a record for the world's shortest national coastline of 3.83 km, not counting landlocked nations and it is recognised as one of the wealthiest and most expensive places in the world. Malta's Dangerous Overtourism 'Malta named as ninth most overcrowded tourist destination worldwide' is the title of the Malta Independent about the new report. With a history going back seven thousand years Malta, located between Sicily and the northern coast of Africa, is renowned for its sun-drenched beaches, ancient ruins, and vibrant Mediterranean culture. Last year, Malta had a registered population of 563,443 people and over 3.5 million tourists which equates to 6.32 tourists per resident. The Malta Business Weekly reports that the country already has already received "a bit over 1.4 million tourists in the first five months of 2025, which normally constitutes around 35% of all tourists for the year. It seems ever more likely that we will get more than 4 million (possibly 4.1 million) tourists in 2025. Last year we had 3.6 million tourists. From 2019 we have increased tourist arrivals by 54%, but real income from tourism has increased by 51%.' In the summer months, Malta's residents have to put up with crowds of tourists, especially young people arriving in low fare flights and cruise passengers, which has raised alarm from environmentalists and local residents of an 'environmental collapse.' The growth in tourist numbers is particularly affecting one of its most iconic, photographed and fragil sites, the Comino Island's Crystal Blue Lagoon, which according to local reports, has reached a tourism breaking point with over 10,000 visitors from across the world per day. A beautiful 1.4-square-mile natural pool with crystal-clear waters and striking limestone formations, the Cristal Blue lagoon has been transformed from a once tranquil place for swimming and snorkeling, into an overcrowded area full with boats and sunbathers during peak season, resulting in a growing imbalance between the polluting tourism and environmental sustainability of rare bird habitats and protected marine zones. This is how the BBC describe the situation at the Comino's Cristal Blue Lagoon: "shoulder-to-shoulder crowds jostle for space, litter spills from overflowing bins and tangles in trampled rock rose shrubs, while gas-guzzling powerboats blast music and leave behind a trail of environmental damage. Frustration over Comino's overtourism has been growing for years, with some disillusioned visitors going as far as to call the day-trip experience from Malta a 'scam' and overcrowded boats, limited amenities and worsening environmental degradation have led to mounting pressure on authorities to act."

"I flew 10 hours to viral Italian holiday hotspot - it was NOTHING like online"
A mum took her family on holiday to Positano, Italy, after seeing "beautiful and calm" videos online – but said it was "complete chaos" with so many tourists they could barely move. Regina Simmons, 38, flew 10 hours from Las Vegas to Italy and visited Positano on June 1 after seeing clips on TikTok. She expected "amazing views" and "calm empty streets," but described the town as overcrowded, with tourists walking "shoulder to shoulder" through narrow streets. Regina said the photos must be edited to remove people and warned, "Don't believe everything you see on social media."
