The IMO said that magma - molten rock - was accumulating at a depth of around 5km (3m) northwest of Thorbjorn mountain. The Blue Lagoon is easily visible from the mountain. The owners of the famed turquoise hot springs said they would close the site until 16 November out of concern for employees' welfare. The Met Office said an earthquake of 5.0 magnitude, the largest since the increased activity began, was detected shortly past midnight on Thursday in the Fagradalsfjall volcanic area, around 30km from the capital Reykjavik. Ingibjorg Lilja Omarsdottir of the Icelandic Civil Protection Agency has been posted...

The death toll from a volcano eruption in Indonesia has risen to 22 after nine more bodies were discovered, a search and rescue agency official said Tuesday. Mount Marapi on the island of Sumatra spewed an ash tower 9,800 feet — taller than the volcano itself — into the sky on Sunday. Hundreds of rescuers have worked for days to find missing hikers, which numbered 10 on Tuesday before the local rescue agency's announcement that most had been found, bringing the days-long search closer to an end. "Nine of 10 missing victims were found dead this afternoon and at the...

JAKARTA, Indonesia – Indonesia’s Marapi volcano in the West Sumatra province erupted on Sunday, sending a thick plume of toxic ash and smoke nearly 10,000 feet into the air and was accompanied by a deafening roar that could be heard for miles, according to the country’s disaster management agency. Indonesia’s National Agency for Disaster Countermeasure (BNPB) said in a news release that the nearly 9,500-foot volcano began erupting just before 3 p.m. local time Sunday, and volcanic ash rain from the eruption was reported to have occurred in the Nagari Lasi area of the Canduang District in West Sumatra’s Agam...

It also changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to...

The whole of Iceland 'is on edge' as experts say earthquakes which have been rumbling beneath the surface for days and have torn through a town are a precursor to a volcanic eruption. More than 700 quakes have been recorded in the southwestern Reykjanes Peninsula since yesterday, and despite them being slightly weaker than in previous days the Fagradalsfjall volcano is still expected to erupt. Iceland has been shaken by thousands of tremors over the past few days, with a state of emergency declared on Friday and around 4,000 people ordered to leave the fishing community of Grindavik. Evacuated residents...

California's supervolcano that has the power to bury Los Angeles in more than 3,000 feet of ash is showing signs of activity. Scientists at the California Institute of Technology (Caltech) identified over 2,000 earthquakes rumbling throughout the Long Valley Caldera in recent years. The team conducted a new investigation to see if the seismic activity was a sign of impending doom or that the risk of a massive eruption was decreasing. Caltech researchers created detailed underground images of the caldera, finding that the recent seismic activity results from fluids and gases released as the area cools off and settles down....

A new study led by the University of Oxford has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large CO2 source, rivaling that of volcanoes. The results, published today in the journal Nature, have important implications...

Here’s everything you need to know about how often Mount Etna erupts and how it affects travel and tourism. Mount Etna, one of the world’s most active volcanoes, has been making headlines in the last few years thanks to dramatic eruptions. It lies on the Italian island of Sicily and looms over the city of Catania. This week, Catania airport was forced to close temporarily and driving restrictions were put in place following an eruption that spewed ash over the surrounding area. If you’re thinking of booking a holiday to Catania and eastern Sicily, you may be concerned that volcanic...

Kilauea, one of the most active volcanoes in the world, began erupting Sunday after a two-month pause, displaying glowing lava that is a safe distance from people and structures in a national park on the Big Island.

Tonga Eruption Blasted Unprecedented Amount of Water Into Stratosphere The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, could end up temporarily warming Earth’s surface.When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The underwater eruption in the South Pacific Ocean also blasted an enormous plume of water vapor into Earth’s stratosphere – enough to fill more than 58,000 Olympic-size swimming pools. The sheer amount of water vapor could be enough to...

The current heat wave is being relentlessly blamed on increasing levels of carbon dioxide in the atmosphere, but there is a much more plausible explanation, one that is virtually endorsed by two of the world’s leading scientific organizations. It turns out that levels of water vapor in the atmosphere have dramatically increased over the last year-and-a-half, and water vapor is well recognized as a greenhouse gas, whose heightened presence leads to higher temperatures, a mechanism that dwarfs any effect CO2 may have. So, why has atmospheric water vapor increased so dramatically? Because of a historic, gigantic volcanic eruption last year...

A massive 7.2 magnitude earthquake has increased the risk of a volcano in Alaska erupting imminently as the aviation level was raised to red. The Shishaldin Volcano has been spewing great plumes of ash into the air since July 11, according to the Alaska Volcano Observatory (AVO). A US Coast Guard overflight confirmed lava erupted the same day within the summit crater. The latest data from the AVO, as of just before midnight on July 15, showed frequent explosion signals are being detected, with some explosions sending plumes of ash as high as 20,000 ft above sea level.

Some 717 million years ago, glaciers covered the globe. Earlier eruptions may have triggered the event. CLAUS LUNAU/SCIENCE SOURCE ***************************************************** About 717 million years ago, a climate catastrophe struck the planet, as temperatures plunged and glaciers enveloped the globe. The cause of this “Snowball Earth” episode has been mysterious, but it took place around the same time as a massive outburst of volcanism. Many researchers thought there might be a connection. But the timing was uncertain. Now, more precise dates, reported last month in Earth and Planetary Science Letters (EPSL) and in November 2022 in Science Advances, show the eruptions...

Officials have raised the alert level due to various seismic events being recorded.

Some background; in the last couple of weeks, I've been posting pictures of "Great Falls", starting with the Great Falls nearest to me, on the Potomac River. I speculated that there are several "Great Falls" around (there are). A humorous wag posted that one of them must be the "Great Falls of Bire" (rim shot, please). I replied to him that if Ireland had a great falls, this would be the "Great Falls of Eire". So I Googled to find out if Ireland had a great falls. It doesn't, but in searching, I discovered the "World Waterfall Database", which right...
