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...

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...

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...

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...

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...

Flights from Catania airport in Sicily were grounded on Sunday after volcanic ash from an eruption of Mount Etna covered the runways. Airport authorities announced that flights would be suspended until Monday 9 a.m. local time (3 a.m. ET) due to the fallout from the eruption on Twitter. They later told CNN that flights are expected to resume at midday Monday (6 a.m. ET).

Mexican authorities on Sunday raised the warning level for the Popocatepetl volcano to one step below red alert as smoke, ash and molten rock spewed into the sky posing risks to aviation and far-flung communities below. The huge volcano that towers above Mexico City is considered one of the most dangerous in the world because some 25 million people live within a 60-mile radius. Sunday's increased alert level - to 'yellow phase three' - comes a day after two Mexico City airports temporarily halted operations due to falling ash, which also forced 11 villages to cancel school sessions.

A chain of undersea volcanoes, also known as seamounts. (NOAA Ocean Exploration) Less than one-quarter of Earth's entire ocean floor has been mapped, leaving gaping holes in our understanding of the underwater realm. Accidents await in the void: undiscovered seamounts – ancient mountains formed by volcanic activity – can rise thousands of meters in the darkness, putting unsuspecting submarines at risk. Led by earth scientist Julie Gevorgian of the Scripps Institution of Oceanography in California, a team of scientists has just discovered more than 19,000 new seamounts using a new batch of satellite data. That so many underwater peaks have...

A volcano erupted early Tuesday on Russia's far eastern Kamchatka Peninsula. The eruption of Shiveluch, one of the area's most active volcanoes, sent clouds of dust more than 65,000 feet into the sky, engulfing villages in gray dust. The ash cloud extended over more than 300 miles and the event triggered an aviation warning. Officials closed the skies over the area to aircraft and local authorities advised residents to stay indoors, with schools shuttered and power supplies cut for two villages for a few hours.
