When Mount Ruang in Indonesia underwent multiple explosive eruptions last week, volcanic gases were flung so high they reached the atmosphere’s second layer, tens of thousands of feet above ground. The force of Mount Ruang’s eruptions this week ejected an ash plume tens of thousands of feet in the air and sent some volcanic gases more than 65,000 feet into the air, according to satellite estimates – about 25,000 feet higher than a commercial airplane will typically fly. The eruption’s potential impacts to weather and climate are starting to come into focus, even as the danger posed by the volcano...

At least 11,000 people were forced to evacuate after a volcano erupted in Indonesia. The government is encouraging residents to leave with fears that part of the volcano could break off into the ocean and trigger a tsunami.

A volcano erupted several times in Indonesia's outermost region Wednesday, with authorities raising the alert level to its highest point after the dome spewed a column of smoke more than a mile into the sky and forced hundreds to evacuate. Mount Ruang, a stratovolcano in North Sulawesi Province, first erupted at 9:45 pm on Tuesday (1345 GMT) and four times throughout Wednesday, the country's volcanology agency said. The alert level for the volcano, which has a peak of 725 meters above sea level, was then raised on Wednesday evening from three to four, the highest possible level in the four-tiered...

STORY: Volcanic vortex rings are natural, near-perfect circles of gas emitted from a volcano under specific conditions and scientists say Mount Etna emits more than any other volcano on earth. It is a relatively rare phenomenon caused by a constant release of vapours and gases. The gaseous mass ascends rapidly through the central part of the conduit, promoting the formation of rings by wrapping the gas upon itself in a vortex motion. Giuseppe Barbagallo, of the South Etna Alpine Guides Group, said the last time this happened at the Etna volcano was last December. The rings have led locals to...

Scientists have discovered a gigantic volcano on Mars near the planet’s equator that remained unnoticed for decades, according to newly published research. The huge volcano was found in the Red Planet’s eastern Tharsis volcanic province, along with what researchers interpret to be a large sheet of buried glacial ice beneath the Martian surface. The discovery came as a surprise, partly because orbital spacecraft have photographed this region of Mars since the early 1970s. Hidden in plain sight now for decades, the giant volcano, which has undergone extensive erosion over time, somehow remained unnoticed. The feature has been given the temporary...

Scientists have detected a 'great swarm' of earthquakes off the coast of Washington clocking as many as 200 in a single hour during one day. Geologists at the University of Washington said the quakes could lead to the Juan de Ruca Ridge erupting within a few weeks or years - but the effects are believed to be mild and not likely impact anyone on land. The underwater volcano sits more than 16,000 feet below the Pacific Ocean and about 150 miles off the coast of Washington. With more than a thousand tiny quakes detected in one day, this is the...

Most of us are familiar with the eruption of Mount Vesuvius in AD 79, which destroyed the Roman cities of Pompeii, Herculaneum, Oplontis, and Stabiae. But did you know that this was not the first time that Vesuvius unleashed its fury on the surrounding lands? Centuries before, around 2000 BC, another massive eruption buried a Bronze Age village in Italy, preserving it in volcanic ash and mud. This village is known as Afragola.In this video, we will show you how archaeologists and scientists uncovered the secrets of this fascinating site.You will discover how ancient plants helped reveal the season of...

Created by a 7.3-magnitude earthquake in 1959, Yellowstone's Red Spouter is a thermal with many personalities. Depending on the season, it can be a hot spring, a boiling mudpot or it can just spew hot gas. Many of Yellowstone National Park’s thermal features are defined by their personalities. The regularity of Old Faithful, the colossal noise and steam clouds of Steamboat Geyser or the colorful palette of the Artists’ Paintpots. By that logic, the Red Spouter might be Yellowstone's most ambitious. Instead of building a reputation around a single personality, it tries to — and succeeds at — being many...

Lava has reached the surface in Iceland

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...
