April 28, 2016 - NEW ZEALAND - White Island erupted last night.

The volcanic island, off the coast of the Bay of Plenty, erupted yesterday between 9.30pm and 11pm, GNS Science said.

As a consequence of this activity the Volcanic Alert Level is now raised to Level 3 (Minor Volcanic Eruption) and the Aviation Colour Code to Orange.

No eruptive activity has been seen since about 11pm yesterday.

The eruption was accompanied by a moderately elevated seismic activity, GNS said. The seismic activity is now back to normal.

Material appears to have been deposited over north side of the crater floor and up onto north crater wall. There is not yet a clear view of crater area visible from cameras.

Volcanologists are monitoring the volcano and further information will be released as soon as it is available.

Over the last couple of weeks, GNS scientists have observed a fall of 2m in the water level of the crater lake.

However, they have not noted any changes in other monitored parameters, like the amount of volcanic gas being emitted, fumarole temperatures and the presence of volcanic tremor or earthquakes.

During a visit last week by GNS volcanologist Brad Scott he was able to confirm the lake level had dropped 2m in the last 2 weeks. The lake was now about the same level as it was in 2014. The drop in water level of the crater lake has revealed several islands or crater outlines and the lake temperature has increased 2C, from 56C to 58C, since February.

There had been a small decrease in the temperature of the hottest fumarole (169C to 161C) since February. The SO2 gas output has ranged between 90 and 480 tonnes per day (1.0 to 5.5 kg per second) of gas during the last 5 weeks. These are typical values for White Island.

The level of volcanic tremor continues to vary, but remains below those observed in 2012 when unrest was stronger and small eruptions occurred.

GLOBAL VOLCANISM: The Latest Report Of Volcanic Eruptions, Activity, Unrest And Awakenings – April 24, 2016!

April 25, 2016 - EARTH - The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe.

Kliuchevskoi (Kamchatka): The activity of the volcano has intensified, in particular during the past 24-36 hours. KVERT reported that strong strombolian explosions produced an ash plume that rose to 8-9 km altitude that drifted more than 400 km to the SW.

Webcam images have been mostly unclear, but view from this evening (dawn in Kamchatka) suggest that a new lava flow might have started to descend the volcano's flanks, which would be a typical occurrence if the magma supply rate has indeed increased. An intense thermal anomaly is being recorded on satellite data as well.

KVERT alerted this morning that the "explosive eruption of the volcano continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft." The aviation color code was raised to ORANGE.


Sinabung (Sumatra, Indonesia): The volcano's current and long-lasting eruption (now well in its 3rd year) continues essentially unchanged: viscous lava slowly rises into the summit crater, building up a complex dome that over-spills as sticky lobes onto sections of the upper outer slopes on the southeastern side.

Explosion from Sinabung last Friday

When these steeply emplaced lava lobes become too large, they also become unstable and begin to collapse. These collapses generate glowing rockfalls and small to moderate pyroclastic flows when enough material rich in gas is involved. From time to time, accumulated gas trapped beneath the dome also gives way to vertical explosions. These explosions have been occurring almost daily over the recent months, producing ash plume that rise 1-2 km, typically.


San Cristobal (Nicaragua): The volcano had a series of new explosive eruptions on Friday, producing ash plumes that rose up to approx. 2 km above the summit crater, drifted south and caused moderate ash fall in areas up to 10-15 km south and southeast of the volcano, including Las Brisas, Santa Narcisa, and Chichigalpa town.

The new series of eruptions began on 22 April around 10:20 local time with a first explosion, followed immediately by a stronger one (image). Weaker explosions followed intermittently throughout the day, but activity seems to have faded again as of today.

Whether these eruptions were caused by superficial steam explosions (phreatic activity) or involved new magma that has risen inside the volcano's conduit is unknown at the moment (without analysis of the ash and seismic and other parameters)

In any case, the volcano has been at elevated unrest for some time and might continue to do so for a while: unconfirmed minor explosions seem to have occurred earlier this year in February and similar, more significant explosions took place in March and June last year (2015).


Nevado del Ruiz (Colombia): The volcano produced a small ash plume today, Manizales volcano observatory reported to Washington VAAC. Webcam views are obscured by weather clouds.

Sporadic mild ash emissions have been occurring from the volcano from time to time during the past weeks.

MONUMENTAL GEOLOGICAL UPHEAVALS: Massive 2015 Alaskan Landslide That Triggered A Mega-Tsunami Is Estimated To Be The BIGGEST NON-VOLCANIC Landslide In North American History - Over 200 MILLION METRIC TONS Of Rock Landed On The Tyndall Glacier!

April 11, 2016 - ALASKA - After a period of heavy rains, about 200 million metric tons of rock tumbled down a remote Southeast Alaska mountain. The massive landslide, lasting about 60 seconds, occurred on October 17, 2015, and landed on the toe of Tyndall Glacier and into Taan Fiord in Icy Bay, Alaska.

The event generated a local megatsunami that sheared trees more than 152.4 meters (500 feet) up on a peninsula within the fiord. It was big enough to register at the nearest tidal gauge 155 km (96.3 miles) away. For comparison, the 2011 tsunami in Japan reached about 39.6 meters (130 feet) above sea level.

This event, now estimated as the biggest nonvolcanic landslide, by volume, in North America's written history, was registered by special seismograms monitored by the Global CMT Project at Lamont-Doherty Earth Observatory whose seismologists Göran Ekström and Colin Stark have invented a new technique that uses seismic waves to detect landslides in remote areas where they might otherwise go unrecorded.

Since winter snows hid the damage generated by the tsunami it took several months to see the extent of the damage. Upon hearing a report from a pilot colleague that the landslide area of Icy Bay was free of snow, glaciologist Chris Larsen of the University of Alaska Fairbanks' Geophysical Institute flew there in his Cessna 180. Larsen used a camera system mounted in his plane to make a high-resolution map of the landslide and the path of the megatsunami.

"It almost blows away everything in the historical record except for Lituya Bay," Larsen said. "It's really a unique event to have a tsunami 100 meters (328 feet) high. If it was September or any time in the summer, the wave could have gotten a fishing boat or two.

"The Lituya Bay landslide, Larsen referred to, occurred in 1958 after a powerful M8.0 earthquake. The wave that followed ripped spruce from 518 m (1 700 feet) up a mountain slope and left trimlines in the bay that are visible today.

Icy Bay and places like it will have more landslides as time goes on, Larsen said. Warmer temperatures melt more glacial ice that buttress hillsides. When the ice melts, oversteepened slopes will fail. Sometimes it takes a big rain or an earthquake to shake them down.

"These megatsunamis are infrequent in the historical record but will most likely increase," Larsen added. - The Watchers.

GLOBAL VOLCANISM: Experts Sent In To Monitor Volcano Hotspot In Nicaragua - As 3 More Magma Mountains Erupt!

February 23, 2016 - NICARAGUA - Disaster experts are keeping a close eye on a seismic hotspot after three large volcanoes began erupting with fears of a fourth in the offing.

Volcano experts from the US, UK, Costa Rica and local geologists are observing activity at four active peaks in Nicaragua after the flurry of explosions.

The biggest, and most active, is the enormous 1,297-metre Momotombo stratovolcano, near the city of León.

Momotombo, on the north of Lake Managua 25 miles from Nicaragua's capital Managua, blew for the first time in 110 years in December, and has been active ever since.

In a post about the situation Costa Rican English-speaking news site The Tico Times wrote it had sent "geologists and local townspeople into a tizzy" It added: "In fact, there's been so much volcanic and seismic activity in Nicaragua lately that experts from the United States, the United Kingdom, Nicaragua and Costa Rica are carefully studying and observing the situation."

Geologists from the US Geological Survey announced last week they are studying and assessing risks from Momotombo and the other active volcanoes in the country.

Both Télica and Masaya began erupting at the same time as Momotombo, and continue to do so.

Meanwhile, Cerro Negro, which has so far not erupted, recorded bursts of seismic activity last week. - Express.

PLANETARY TREMORS: 2.9 Magnitude Earthquake Recorded Near Mount St. Helens, Washington - USGS!

February 9, 2016 - WASHINGTON STATE, UNITED STATES - A 2.9-magnitude earthquake hit just south of Mount St. Helens Monday morning, according to the U.S. Geological Survey.

The quake was recorded at 8:50 a.m.

The earthquake, according to the USGS, wasn't very strong. Only three people reported feeling it, as of 10:30 a.m.

It's the strongest earthquake in Washington in February. A 2.6-magnitude quake was reported Feb. 5 near Tacoma. - MyNorthwest.

GLOBAL VOLCANISM: Seismologists Watching Glacier Peak In Washington - After 4 Earthquakes In Just Under 4 Hours!

November 27, 2015 - SEATTLE, UNITED STATES - Four earthquakes struck within hours of each other Wednesday afternoon near Glacier Peak in Washington.

The first two earthquakes registered at magnitudes 3.1 and 3.5. The first earthquake occurred at 12:11 p.m. The second registered roughly an hour later at 1:20 p.m. Then a third earthquake — a magnitude 1.6 — occurred at 2:33 p.m. And finally a fourth earthquake — a magnitude 1.4 — was registered at 3:44 p.m. All the quakes were recorded roughly 19-21 miles east-southeast of the town of Darrington.

Seth Moran, geophysicist at the University of Washington, tells KIRO Radio they're keeping a close eye on the area and continue to watch the seismic records. "Magnitude 3 earthquakes happen in Washington and Oregon a number of times per year," Moran said. "The one thing that makes these potentially interesting in a different way is they're somewhat close to Glacier Peak."

The quakes, about three miles from Glacier Peak, occurred where there haven't been a lot of magnitude 3 earthquakes in the past, according to Moran. "The last time there was a magnitude 3 in the vicinity was in 1991," Moran said.

However, there isn't a great network of seismic instruments in the area. There have been no reports of damage or injuries.


WATCH: Mount Rainier is considered the world's most dangerous volcano because of its size and how close it is to population centers, but there's another mountain you've probably never seen that's finally getting attention for the risks it poses.

According to the USGS, the last time Glacier Peak erupted was 1,100 years ago. Mount St. Helens and Glacier Peak are the only volcanoes in Washington state that have been explosive in the past 15,000 years. - My Northwest.

November 21, 2015 - ICELAND - Eyes are back on Iceland's Bárðarbunga volcano following a magnitude 3.2 earthquake that hit the caldera of the volcano yesterday.

Monitoring by the Icelandic Met Office has recently revealed significantly greater seismic activity than any time since the 2014-15 eruption in the adjacent Holuhraun lava field.

Bárðarbunga is one of Iceland's most powerful volcanoes and is located under the country's famous Vatnajökull glacier.

The Met Office's Einar Hjörleifssonhas indicated that the situation is being monitored closely.  - Iceland Monitor.

 

GLOBAL VOLCANISM: Could Mount St. Helens Erupt Again - Volcanic Tremors Hint Of Magma Being Injected?!

Earthquakes that occurred before the May 1980 eruption of Mount. St. Helens may have been caused by magma being injected from one chamber to another.

November 10, 2015 - PACIFIC NORTHWEST, UNITED STATES - The eruption of Mount St. Helens on May 18, 1980 has claimed 57 lives and caused serious damage to homes and infrastructure.

Now, scientists have revealed that the volcano could possibly erupt again in the future based on findings of a pioneering $3 million study of the volcano's plumbing system.

Geologists who studied the volcano have found a second enormous chamber lying between seven to 23 miles beneath the surface.

This massive pool of molten rock was found connected to a smaller chamber lying directly beneath the volcano.

How these two chambers are connected is helping scientists understand the sequence of events prior to the 1980 eruption, whose strength of explosion destroyed the topmost peaks of the mountain.

Matching the newly discovered magma reservoirs with earthquake data also sheds light on how the deadliest eruption in U.S. history occurred.

The researchers said that the series of tremors that occurred in the months leading to the 1980 eruption may have been caused by magma pumping from the lower to the upper chamber of the volcano, which caused the pressure inside the upper chamber to dramatically increase resulting in the deadly explosion.

"We can only now understand that those earthquakes are connecting those magma reservoirs," said Rice University seismologist Eric Kiser. "They could be an indication that you have migration of fluid between the two bodies."

Reporting the findings of their study at the annual meeting of the Geological Society of America in Baltimore, Maryland on Nov. 3, the researchers said that more tremors have been observed in the area suggesting that more magma is being injected.

"A cluster of low frequency events, typically associated with injection of magma, occurs at the northwestern boundary of this low Vp column," the researchers reported. "Much of the recorded seismicity between the shallow high Vp/Vs body and deep low Vp column took place in the months preceding and hours following the May 18, 1980 eruption. This may indicate a transient migration of magma between these two reservoirs associated with this eruption."

After the 1980 eruption, the volcano started to erupt again in 2004 but it fell silent in July 2008. Nonetheless, Mount St. Helens is still considered a high risk volcano and is closely monitored by the U.S. Geological Survey. The researchers said that their findings could offer a crucial early warning system of a potential eruption. - Tech Times.

GLOBAL VOLCANISM: Geologists - Hidden Cascades Volcano May Pose A Threat!

Glacier Peak (Photo: KING)

May 20, 2015 - SEATTLE, UNITED STATES - Monday marks the 35th anniversary of the eruption of Mount St. Helens that killed 57 people.

Mount Rainier is considered the world's most dangerous volcano because of its size and how close it is to the population centers of Tacoma and Seattle.

But there's another mountain you've probably never seen that's getting attention for the risks it poses to the Seattle area.

Unlike most of the volcanoes in the Cascade Mountains that are viewable from Interstate 5 or even Seattle, few people notice Glacier Peak. It lurks within in the northern Cascades in Snohomish County and has a record of violent, even extreme eruptions.

Jim Vallance a geologist at the Cascades Volcano Observatory, was a young field assistant on Mount St. Helens in the wake of the 1980 eruption. He remembers doing field work on St. Helens in 1979."It was quiet. You may remember if you were an old timer in the Northwest, that Spirit Lake was a blue body of water with cabins all around," said Vallance. "That all changed dramatically in 1980."

"As impressive as it was, Mount St. Helens was actually hundreds of feet shorter than Glacier Peak," Vallance points out. "The summit is right here."

Now his role at the observatory is dedicated to understanding Glacier Peak.

Every year's brief field season is on foot or with the help of pack mules to bring out more samples that lead to more understanding.

"I'm working on a giant four-dimensional puzzle. I'm trying to work out what happened in the past, when did it happen and how often," said Vallance.

When a volcano's glaciers melt during an eruption, it picks up massive amounts of fine dirt and debris. It becomes what's called a lahar.


WATCH: Mount Rainier is considered the world's most dangerous volcano because of its size and how close it is to population centers, but there's another mountain you've probably never seen that's finally getting attention for the risks it poses.

In the case of Glacier Peak, the geological record shows lahars reaching as far away as Mount Vernon, Burlington, Stanwood and Puget Sound by following the Skagit and Stillaguamish rivers.

But while some mountains, including St. Helens and Rainier, are heavily wired with sensors, there is but one lone seismometer on the west flank of Glacier Peak. That's about to change.

Next year, four boxes, each packed with a sensitive seismometer, global positioning antennas and other sensors, will be installed on Glacier Peak. The seismometers can tip off scientists to the first faint signals that magma is on the move.

"Most typical quakes around volcanoes are very small, very low magnitude," said Ben Pauk, a geophysicist who works with sensing technologies.

Then, as seen in the buildup to a 2004 eruption on Mount St. Helens, the quakes are constant.

"It's going to generate what's called volcanic tremor. So the ground is just constantly shaking," said Pauk. "And that gives us a really good indication of what type of eruption is going to occur."

Global positioning antennas measure when the mountain is actually starting to swell.

When could an eruption on Glacier Peak occur? There's no telling, said Vance, remembering that summer of 1979, when Mount St. Helens seemed so quiet.

"It could be this year or a thousand years," he said. - KSDK.

GLOBAL VOLCANISM: Eruption Like Mount St. Helens - "It Will Happen Again In Cascades"!

May 16, 2015 - U.S. PACIFIC NORTHWEST - Mount St. Helens caught science a little by surprise.

A volcano hadn't erupted on the United State mainland outside Alaska and Hawaii since California's Lassen Peak in early 20th Century.

And modern science had yet to witness an eruption quite like St. Helens.

"I think this was a turning point in the way people approached these kinds of potentially active, explosive volcanoes," said Mike Dungan, a volcanologist with an office at the University of Oregon.

St. Helens didn't just erupt: it blew up.

The force of the May 18, 1980, eruption wasn't just vertical; it was lateral, sending a side of the mountain rocketing down slope as a wall of boiling mud and rock.

The eruption killed 57 people - and put scientists and policy makers on notice.

"It's only a matter of a short time - decades or something - before another one of these things occurs," Dungan said. "A sector collapse eruption like Mount St. Helens - it will happen again in Cascades."

Research at the University of Oregon is shedding new light on the cause of the explosion.

Geologists like PhD student Kristina Walowski are conducting research into how ocean water seeps into offshore plates as they plunge deep into the earth.

"What's really interesting is that water is really important because it lowers the melting temperature of a rock and when that happens you can create magma," she said.

Mount St. Helens viewed aerially from the northeast before the 1980 eruptive activity. Dashed line marks boundary of area removed by the May 18 blast.

"The water is really the key thing that causes the expansion, just like when champagne comes jetting out of a bottle," said Paul Wallace, professor geological science at UO. "It's a foamy material because of the gas present in gas bubbles."

The May edition of Nature Geoscience published the findings by the Oregon team, funded by a National Science Foundation Grant.

"Ultimately the water that makes them so explosive is coming out of the ocean," Wallace said. "And eventually as the plate moves like a conveyor belt, it gets returned back down into the inside of the earth.."


WATCH: Eruption like Mount St. Helens - 'It will happen again in Cascades'.

"It's not like you're pouring cups of water into the interior of the earth, right?" Walowski said. "There's a complicated set of reactions and breakdowns where these rocks are changing shape, and releasing water little by little by little."

So which of the Cascade volcanoes is next in line to erupt?

It's difficult to predict, but geologists are watching.

"We're really in the midst of a technology explosion when it comes to monitoring volcanoes, using all kinds of things using remote sensing instruments on satellites," Wallace said.

"Mount St. Helens is still the most frequent in the Cascades," Walowski said, "and based on that, it may be the most likely to go again." - KVAL.

GLOBAL VOLCANISM: All The World's Volcano Webcams - Never In The History Of Volcanology Have So Many Volcanoes Been Monitored! [LIST]

Explosive eruption at Mexico's Colima, capture on the Webcams de Mexico camera on April 2, 2015. Webcams de Mexico (captured by Erik Klemetti)

April 5, 2015 - EARTH - Never in the history of volcanology have so many volcanoes been monitored. We have the ability to sit and watch hundreds of volcanoes as they sleep, rumble or erupt — all from the comfort of our homes or offices. This instant connectivity to volcanoes in some of the most remote parts of the world is what gives us the impression that there are more volcanic eruptions today than in the past. There really aren’t more, but rather we hear about or see the eruptions much faster. With the network of webcams and the peering eyes of satellites, almost no volcano can erupt on the planet and we not notice. So, fear not, volcanism isn’t on the rise but our ability to see the action live is.

Check out the list below of volcano webcams, sorted by geographic location. I can’t guarantee that they all work — webcams are tricky to keep operational even in ideal conditions — but even clicking through a few shows just how restless many volcanoes around the globe are. If you find a broken link or discover a new webcam not on the list, let me know in the comments. Be sure to bookmark this page so you can find it when some volcano does start acting up around the world!
