Lava From Kilauea"s Eruption In Hawaii Is Flowing Faster Than You Can Run
The Hawaiian Volcano Observatory reports that "standing waves" were visible in a channel of lava flowing at speeds up to 17 miles per hour. Of course, the eruption slows down as it spreads out, forming so-called "pahoehoe" flows that creep along. But it's important to know just how fast the stuff can move because there's no reason a channel can't suddenly change. Running at 17 mph would be a pretty fast sprint for a person that's in good athletic shape. You could cover a 100 meter dash in about 13 seconds at that rate, provided you're on a nice flat and even track. So to be able to escape a close-range, full-speed lava flow coming right at you, you'd need to run at full-speed the other direction and your full speed had better be on par with the fastest people you know.

Which Volcanoes Are Most Overdue for Eruption?
Like earthquakes, volcanic eruptions are almost impossible to predict. Scientists aren’t at the stage yet where they can reliably tell when an eruption is imminent, but they’re steadily getting there. What’s more, the suggestion that some volcanoes are more “overdue” than others is a notion that resides in the eye of the beholder.

Hawaii"s Volcano Is Literally Erupting Gems
Hawaii's Kilauea volcano has been fiercely erupting for well over a month. Now, residents are finding little green gems that have fallen out of the sky during Kilauea's eruption. The green gems are olivine crystals, a common mineral found in Hawaii's lava. At jewelry quality, the mineral is called peridot. As the volcano erupts, it blasts apart molten lava, allowing for green olivine minerals to be separated from the rest of the melt and fall as tiny gemstones.

Researchers were listening for thunder in the middle of a volcanic eruption. That’s exactly what some researchers managed to record during eruptions of Alaska’s Bogoslof volcano last year. They noticed that cracks and pops in the recordings lined up with the timing of volcanic lightning in the same area. Volcanic lightning occurs when eruptions that send a lot of ash into the atmosphere. During their speed run into the air, the ash particles rub against each other, creating an electric charge a lot like when you rub a balloon against your hair. As the particles spread out, that electric charge discharges into lightning….and apparently, thunder.

The secrets of garnet reveal source of water to fuel powerful volcanoes and earthquakes
Among geologists who study powerful earthquakes and volcanoes, there is a mystery: as one of Earth's tectonic plates slides beneath another in a subduction zone, water is squeezed from certain minerals, lubricating earthquakes and fueling volcanoes in hot spots like the Pacific Ocean "Ring of Fire." But equations that predict where the forces of subduction wring water from stone consistently point to locations far from the site of actual cataclysms. By applying a new spectroscopy technique to garnet containing fragments of quartz, metamorphic petrologist Frank Spear of Rensselaer Polytechnic Institute thinks he's solved the puzzle. His early research shows that the equations are incomplete, lacking the significant variable of "overstepping," the additional energy needed to initiate a process, in this case, the decomposition of water-bearing minerals.

“We visited the peak of the Turrialba Volcano between the month of December 2017 and the first two weeks of January 2018 to work on taking samples of ash expelled recently and carry out measurements of the activity of the active crater. The activity is dominated by an intense degasification of the active crater, with sporadic explosions every 30 minutes to an hour. During this emanations, particles of ashes are released that reach heights of more than 300 meters above the crater. In the field we can clearly see a series of phreatic volcanic deposits, phreatomagmatic –strombolianic (eruptions resulting from interaction between water and magma and mildly explosive), generated since October 2014 and to date. In our visits we observed several explosions of superficial origin, through a camera installed on a drone."

Kadovar volcano (Papua New Guinea): eruption continues to be intense
According to the Rabaul Volcano Observatory (RVO), a short lava flow is descending on the island volcano's flank, but it is unclear whether it has reached the ocean. A seismometer has been installed on the island and is detecting ongoing tremor indicating the continued rise of magma. Emissions of sulfur dioxide also remain high, suggesting that magma supply remains significant.
How the eruption evolves is impossible to predict, but due to its vicinity to the sea water, the risk of large phreatomagmatic explosions (caused when water gets in contact with magma) and potential tsunamis that could be triggered in this scenario is elevated. It will depend very much on the available amount of eruptible magma still stored inside the volcano's plumbing system.

Scientist says volcano could erupt in Papua New Guinea soon
Seismic activity beneath a Papua New Guinea volcano could mean that a major eruption was imminent, a scientist said Thursday. Thousands of people have been evacuated from islands surrounding Kadovar Island off the South Pacific nation's north coast since a volcano there began erupting on Jan. 5, spouting ash. Flights nearby have been canceled due to the risk posed by ash plumes and ships were warned to stay away from the island. Steve Saunders, principal geodetic surveyor at the Rabaul Volcano Observatory in Papua New Guinea, said seismic activity had recently increased beneath the volcano. "The reason we're getting activity is probably because new magma is moving up from deeper down," Saunders told Australian Broadcasting Corp.

Erupting volcano forces 34000 to flee Philippine villages
Glowing-red lava spurted in a fountain and flowed down the Philippines' most active volcano. The eruption has sent more than 34,000 villagers fleeing to safety and prompted police to set up checkpoints to stop tourists from getting too close.
The Philippine Institute of Volcanology and Seismology said the lava flowed as much as two kilometres (1.2 miles) from the often cloud-shrouded crater of Mount Mayon, while ash fell on several villages in northeastern Albay province.

Philippines: Thousands flee as volcano readies to blow
A restive volcano on the brink of a major explosion has forced more than 37,000 people to flee their homes. Mount Mayon, about 500km southeast of the capital, Manila, has spewed ash and streamed lava since Sunday, and authorities are bracing for a major eruption. The local volcanology agency has hoisted the third of a five-tier alert warning system, which means the volcano may be ripe for a "magmatic" eruption in a matter of weeks, or even days.

Here are the six hottest volcanoes to watch in 2018
The eruption of Mount Agung on the island of Bali has sparked worldwide media interest, yet volcanic eruptions in Indonesia are nothing new. Of the country’s 139 “active” volcanoes, 18 currently have raised alert levels, signifying higher than normal seismic activity, ground deformation or gas emissions. On a global scale, in any week in 2017, there were at least between 14 and 27 volcanoes erupting.

Mount Etna may not be a "real" volcano and "could be closer to a giant hot spring"
Etna, one of the world’s biggest and most powerful volcanoes, may have more in common with a giant hot spring than a volcano, a scientist has claimed. Long classed as a stratovolcano, the 3,350 metre-high mountain on the popular holiday island of Sicily also spews out some seven million tonnes of steam, carbon dioxide and sulphur dioxide every year. In a report published in the New Scientist, Professor Ferlito explains the widely-believed theory that the steam, carbon dioxide and sulphur dioxide produced from Etna's eruptions are released from magma as it rises to the surface. But he questions the validity of this conventional explanation, arguing for it to be true, Mount Etna would need to erupt ten times more lava than it already does.

New Eruption at Turrialba Volcano Costa Rica
The latest report from the National University’s Volcanology and Seismology Research Institute (OVSICORI) states that in the past 24 hours the activity in the Turrialba Volcano has been low except in the early hours of this Tuesday when seismic activity was registered between 4 and 4:30 a.m., wish coincides with the emanations of ash that were dispersed to the southwest of the volcano. The Rincon de la Vieja Volcano in Guanacaste also registered some low seismic activity as well as the Tenorio Volcano, area that has recently been affected by an earthquake swarm which caused last week the change of coloration of the Rio Celeste River, however, OVSICORI confirms the latest activity hasn’t affected the river color again.

Volcano in Papua New Guinea little known, hard to predict
People in Papua New Guinea are being warned that an eruption of a volcano in the South Pacific nation could also cause a tsunami. The volcano on small Kadovar Island has been erupting for more than a week, forcing 700 people to leave that island and 3,000 to be evacuated from nearby Biem Island. Flights in the area have been canceled due to the risk posed by the ash plumes. Chris Firth, a volcano expert from the Department of Earth and Planetary Science at Australia's Macquarie University, said Tuesday the steepness of the volcano meant an eruption may trigger landslides into the sea, which could create a tsunami. The volcano was also not well-studied so its activity would be harder to predict.

We All Nearly Missed The Largest Underwater Volcano Eruption Ever Recorded
The Kiwi passenger emailed photos of the strange ocean slick to scientists, who realised what it was – a raft of floating rock spewed from an underwater volcano, produced in the largest eruption of its kind ever recorded. "We knew it was a large-scale eruption, approximately equivalent to the biggest eruption we've seen on land in the 20th Century," says volcanologist Rebecca Carey from the University of Tasmania, who's co-led the first close-up investigation of the historic 2012 eruption.
The incident, produced by a submarine volcano called the Havre Seamount, initially went unnoticed by scientists, but the floating rock platform it generated was harder to miss.

12000 flee as Philippines warns of volcano eruption
The crater of a rumbling Philippine volcano was glowing bright red Monday, with vulcanologists warning it could erupt within days, sending thousands fleeing from their homes. Volcanic earthquakes and rockfalls have shaken the summit of Mayon over the last 24 hours, after a number of steam-driven eruptions, scientists said.
More than 12,000 people have been ordered to leave a seven-kilometre (four-mile) evacuation zone, and there are warnings of destructive mudflows and toxic clouds.
"It is dangerous for families to stay in that radius and inhale ash," Claudio Yucot, head of the region's office of civil defence, told AFP.

Watch: Drones give closer view of active volcano
With the help of drones, researchers are investigating an active Nicaraguan volcano that could pose a hazard to millions of people. Masaya volcano is located in an active volcanic and seismic zone and is nearby Managua, Nicaragua’s capital. The researchers are using many methods, including drones, to study how the volcano and surrounding earth are changing over time. The drones are able to capture high-quality video footage and travel to places inaccessible to humans.

Visit to Biggest Underwater Volcano in Last 100 Years Reveals Deep Sea Mystery
Scientists knew something strange happened when they heard reports of a raft of floating rock near New Zealand back in 2012. That raft eventually grew to around 150 square miles—remains of the largest underwater volcanic eruption in the 20th or 21st century to date, bigger even than Mount St. Helens. But when researchers actually visited the Havre volcano, it was nothing like they expected. Instead of the explosive, underwater Krakatoa-type eruption expected, they found signs of slower-moving lava flows... and realized that a whole lot of data they could have been using literally floated away.

Volcano erupts in Indonesia's Bali, airport remains safe
The latest eruption of Mount Agung occurred at 5:54 p.m. local time (0954 GMT) Thursday. The volcano that has been active since September last year blasted back smoke, billowing 2,500 meters high into the air. Land tremors were also felt during the eruption, which lasted 130 seconds, the agency said. Rain of ash was reported to be affecting villages not far from the volcano summit as the eruption column was 2.5 km high, the agency said.

Surprise awakening of Papua New Guinea volcano forces evacuations
An island volcano in Papua New Guinea has begun spewing ash into the air, forcing the evacuation of more than 500 residents, media and non-profit groups have said.
Kadovar Island, a 365 metre tall volcanic island just north-east of PNG, was thought to be dormant until it began erupting on 5 January. “It’s just a continuous emission of volcanic ash at the moment,” said Cheyne O’Brien, a forecaster at the Darwin Volcanic Ash Advisory Centre.
