Gases from Philippine volcano sicken dozens of children, prompting school closures in nearby towns

taal
Smog containing gases from a restive Philippine volcano sickened dozens of students and prompted 25 towns and cities to shut their schools on Friday as a health precaution, officials said.

There was no imminent threat of a major eruption of Taal Volcano, which authorities said remains at a low level of unrest in Batangas province south of Manila. But they said its emission of sulfur dioxide-laden steam in recent days caused skin, throat and eye irritation for at least 45 students in nearby towns.

Classes were suspended in 25 towns and cities in Batangas to keep students safely at home. Some schools resumed online classes and home learning that were in wide use at the height of the coronavirus pandemic, officials said.

Mount Etna eruption leads to flight cancellations at Sicily's Catania airport

Flights serving the eastern Sicilian city of Catania were halted after an eruption from nearby Mount Etna, local authorities said, bringing fresh travel troubles to the crisis-plagued Italian airport.

The 3,330 metre high volcano burst into action overnight on Sunday, firing lava and ash high over the Mediterranean island. The lava flow subsided before dawn, but ash was still coming from one of the craters.

Flights to and from Catania, a popular tourist destination, were set to remain suspended until 6am on Tuesday morning, the airport operator said in a statement, dashing hopes they could resume on Monday night.

Database with 2,400 prehistoric sites

The role of culture in human expansions: Large-scale collection of digital data summarizes the results of 150 years of research and can be used by amateurs and scientists alike.
Map of Human Expansion

Human history in one click: For the first time, numerous sites relating to the early history of mankind from 3 million to 20,000 years ago can be accessed in a large-scale database. Scientists from the research center ROCEEH ("The Role of Culture in Early Expansions of Humans") have compiled information on 2,400 prehistoric sites and 24,000 assemblages from more than 100 ancient cultures. The digital data collection is available for free to scientists and amateurs and was recently published in the journal PLoS ONE.

The research center is located at the University of Tübingen and the Senckenberg Society for Nature Research, sponsored by the Heidelberg Academy of Sciences and Humanities, and funded in part through the Union of German Academies.

ROAD, the "ROCEEH Out of Africa Database", represents one of the largest digital collections of information about archaeology, anthropology, paleontology and botany based on 150 years of research history, says Dr. Andrew Kandel, University of Tübingen. By joining information about cultural remains, human fossils, animal bones and plants into a unified geographical and chronological framework, the team created a tool that helps analyze the complex aspects of human evolution.

Multiple dust devils spotted at volcano eruption site in Iceland

mmmmmmmm
Huge dust devil takes to the sky. Captured on Iceland volcano eruption webcam. Starts at around 0:45 Other smaller dust devils are also seen.

Iceland Volcano recorded from our live stream of the 2023 eruption.

Fagradalsfjall is an active tuya volcano formed in the Last Glacial Period on the Reykjanes Peninsula, around 40 kilometres (25 mi) from Reykjavík, Iceland. Fagradalsfjall is also the name for the wider volcanic system covering an area 5 kilometres (3 mi) wide and 16 kilometres (10 mi) long.

Most recent eruptions are 2021,2022 and 2023.

Eerily perfect 'vortex rings' keep blowing out of Mount Etna, Europe's most active volcano, here's why

Europe's most active volcano, Mount Etna, is blowing scores of ethereal "vortex rings" every day from a single vent located in one of its most active craters.

On July 23, Boris Behncke, a volcanologist with Italy's National Institute of Geophysics and Volcanology who is based in Sicily alongside Mount Etna, wrote on Twitter that the volcano had been "releasing dozens of gas rings" from a single vent in Bocca Nuova crater for around a week and shows no signs of stopping.

Vortex rings are made from a mix of smoke, steam and other gases released from volcanic vents at high speeds. They can remain airborne for several minutes before eventually disappearing.

Photographer Luca Cosma, who also runs the tour company Etna Hiker, snapped a series of stunning pictures of the vortex rings on July 23 while escorting a group to the Bocca Nuova crater.

Comment: There are other reasons to believe the surge in activity at Etna may mean an eruption is brewing: Mount Etna collapse 'could trigger tsunami in Ionian sea', slow subsidence of 4cm over 15 months detected

A spectacular video showing huge bolts of lightning shooting out of a volcano in a Guatemalan city has gone viral on the internet.

The footage was captured on July 10 by Sergio Garcia in Antigua.

The lightning on top of the Agua volcano looks like the volcano is erupting from its summit.

The breathtaking footage has been viewed more than 3.23 lakh times and amassed close to 4,000 likes.

Scientists discover ancient, underwater volcano is still active — and covered in up to a million giant eggs

Researchers discovered that an underwater volcano nearly a mile beneath the surface off the Pacific coast of Canada is spouting hot fluid, providing a little-known species of skate with an ideal nursery.

Researchers exploring an ancient, underwater volcano off the Pacific coast of Canada have discovered it is still active — and "covered" in thousands of giant eggs.

Before the expedition, the team thought the volcano was extinct and the waters around it frigid. However, they found the underwater mountain — which towers 3,600 feet (1,100 meters) above the seafloor — spouting warm water and encrusted with deep-sea corals. The hot, mineral-rich fluid keeps the surrounding waters toasty, providing ideal conditions for some marine creatures to survive in the deep sea. The researchers were even more surprised to see a Pacific white skate (Bathyraja spinosissima) weaving in and out of the fronds and laying eggs on the summit, nearly a mile (1.5 kilometers) beneath the surface.

Ground deformation instruments continue to detect the caldera floor to be inflated.

According to the latest KAUST recordings, the ground has been uplifted by approx. 30 cm between September 2022 and July 2023.
