Authorities in Iceland on Tuesday warned tourists and other spectators to stay away from a newly erupting volcano that is spewing lava and noxious gases from a fissure in the country’s southwest. 

The eruption began Monday afternoon after thousands of earthquakes in the area, meteorological authorities said. This one comes 11 months after its last eruption officially ended. The eruption is in an uninhabited valley near the Litli-Hrútur mountain, some 30 kilometers (19 miles) southwest of the capital, Reykjavik. 

The area, known broadly as Fagradalsfjall volcano, erupted in 2021 and 2022 without causing damage or disruptions to flights, despite being near Keflavik Airport, Iceland’s international air traffic hub. The airport remained open on Tuesday. 

The Icelandic Meteorological Office said the eruption was initially more explosive than the previous two. Aerial footage showed streams of orange molten lava and clouds of gases spewing from a snaking fissure about 900 meters (half a mile) long. 

“Gas pollution is high around the eruption and dangerous,” the Met Office said. “Travelers are advised not to enter the area until responders have had a chance to evaluate conditions.” 

By Tuesday morning, the fissure and the volume of the eruption had shrunk, scientists said. 

“This has become a small eruption, which is very good news,” University of Iceland geophysics professor Magnús Tumi Guðmundsson told national broadcaster RUV. 

He said the eruption could “certainly last a long time, but luckily we’re not looking at a continuation of what we saw in the first few hours.” 

A 2021 eruption in the same area produced spectacular lava flows for several months. Hundreds of thousands of people flocked to see the sight. 

Iceland, which sits above a volcanic hot spot in the North Atlantic, averages an eruption every four to five years. 

The most disruptive in recent times was the 2010 eruption of the Eyjafjallajokull volcano, which sent huge clouds of ash into the atmosphere and led to widespread airspace closures over Europe. More than 100,000 flights were grounded, stranding millions of international travelers and halting air travel for days because of concerns the ash could damage jet engines.

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
