Kilauea volcano (Hawai'i) activity update: Longest non-eruptive period since 1982; probable end of 1983-2018 eruption
Saturday Nov 10, 2018 18:31 PM | BY: MJFLEGEN
It has now been 66 days since lava was last at the surface at Kilauea. That is the longest gap since the start of the eruption in 1983- there were 65 days between Episode 2 and 3- and the longest since the 4 months between the two 1982 eruptions. And with no signs of imminent renewal, it seems very likely that the current gap will reach the 90 day mark on December 5- which means the eruptive period that started in 1983 has come to end. When eruptive activity does eventually return, it will be an entirely new eruption.

Pacific Vanuatu
Uncertainty for displaced Ambeans waiting to return home
4:55 pm on 12 November 2018
Vanuatu's National Disaster Management Office says it is unclear whether Ambae evacuees will be permitted to return to the island this month as planned.
The government ordered a compulsory evacuation of the 10,000 people on Ambae over two months ago, following the eruption of the Manaro Volcano.

Those displaced are anticipating returning to their homes when the government's state of emergency is lifted at the end of the month.

But a NDMO spokesperson Presley Tari said continued minor volcanic activity on the island means they could be at risk.

"It's still a risk for people to live there. We have some few ash coming down again - but the island is getting back green again. There have been a few times of eruptions, minor eruptions."

Presley Tari said the NDMO is awaiting a decision from the government as to when Ambaens can return to the island.


Bread-crust bubble
\Bred krəst ˈbəb(ə)l\ n.
Tiny, gas-filled beads of volcanic ash with a scaly surface.
Scientists have identified a new type of volcanic ash that erupted from a volcano in central Oregon roughly 7 million years ago. The particles are similar to larger bread-crust bombs, which form as gases trapped inside globs of lava expand, cracking the bombs’ tough exterior. Bread-crust bubbles, each no more than a millimeter wide, have a distinctly crackled surface that can reveal secrets about how volcanoes erupt, researchers reported November 4 at the Geological Society of America annual meeting in Indianapolis.

The researchers had been sifting through other types of volcanic ash in the lab when they spotted the strange ash formations. Viewing the bits of ash through a scanning electron microscope revealed their crusty texture, indicating the gas bubbles expanded rapidly on their way up to Earth’s surface, but did not pop. Analysis of the texture also indicated the bubbles’ depth when they first exploded in the foamy magma. In the case of the Oregon sample, says volcanologist Ben Andrews of the Smithsonian Institution in Washington D.C., the frothy ash formed roughly 500 to 2,000 meters deep — a short distance, geologically — and erupted from the volcano at a rate of about 30 to 80 meters per second.

Loafing around

Newfound volcanic ash is like a mini-me version of bread-crust bombs, which get their name from having a cracked surface that can resemble a loaf of bread. Bread-crust bombs form as gases trapped within a glob of hard-shelled lava expand. This one, about 15 centimeters in diameter, erupted from Mount St. Helens in Washington.

“Where magmas are sitting before they erupt and how fast they erupt — that gives us an idea how to forecast future eruptions,” says Andrews, who discovered the spherical ash particles along with volcanologist Steve Quane of Quest University in British Columbia. The team is now collaborating with another group of researchers to study bread-crust bubbles collected from Laguna del Maule volcano in Chile.

19/11/2018 - Volcano of Fire triggers new exodus just months after killimg Hundreds
Volcano of Fire triggers new exodus just months after killing hundreds

GUATEMALA CITY — Disaster coordination authorities have asked 10 communities in Guatemala to evacuate and go to safe areas after an increased eruption of the Volcano of Fire.

The 10 communities have at least 2,000 residents, but each community will decide if they evacuate or not. Antigua al Rescate, an organization that helped communities after a devastating eruption in June, and a newspaper in the capital reported at least three communities were doing so.

Images of the volcano after midnight showed glowing lava at the summit. The volcano is located among the departments of Escuintla, Chimaltenango and Sacatepéquez in the south-central part of the country.

David de León, spokesman for the National Coordinator for Disaster Reduction, told The Associated Press that at least eight communities should leave.

De León said monitoring of the volcano's activity during the day Sunday showed the intensity of the eruption was being maintained, so the evacuation was called for to protect people.

The 12,300-feet Volcano of Fire is one of the most active in Central America. An eruption in June killed 194 people and left at least 234 missing, although organizations supporting the communities have insisted there are thousands of missing persons. It spewed more ash and lava in October, prompting warnings for the nearby communities.

Ask medieval historian Michael McCormick what year was the worst to be alive, and he's got an answer: "536." Not 1349, when the Black Death wiped out half of Europe. Not 1918, when the flu killed 50 million to 100 million people, mostly young adults. But 536. In Europe, "It was the beginning of one of the worst periods to be alive, if not the worst year," says McCormick, a historian and archaeologist who chairs the Harvard University Initiative for the Science of the Human Past.

A mysterious fog plunged Europe, the Middle East, and parts of Asia into darkness, day and night—for 18 months. "For the sun gave forth its light without brightness, like the moon, during the whole year," wrote Byzantine historian Procopius. Temperatures in the summer of 536 fell 1.5°C to 2.5°C, initiating the coldest decade in the past 2300 years. Snow fell that summer in China; crops failed; people starved. The Irish chronicles record "a failure of bread from the years 536–539." Then, in 541, bubonic plague struck the Roman port of Pelusium, in Egypt. What came to be called the Plague of Justinian spread rapidly, wiping out one-third to one-half of the population of the eastern Roman Empire and hastening its collapse, McCormick says.

Historians have long known that the middle of the sixth century was a dark hour in what used to be called the Dark Ages, but the source of the mysterious clouds has long been a puzzle. Now, an ultraprecise analysis of ice from a Swiss glacier by a team led by McCormick and glaciologist Paul Mayewski at the Climate Change Institute of The University of Maine (UM) in Orono has fingered a culprit. At a workshop at Harvard this week, the team reported that a cataclysmic volcanic eruption in Iceland spewed ash across the Northern Hemisphere early in 536. Two other massive eruptions followed, in 540 and 547. The repeated blows, followed by plague, plunged Europe into economic stagnation that lasted until 640, when another signal in the ice—a spike in airborne lead—marks a resurgence of silver mining, as the team reports in Antiquity this week.

Maybe vulcanic lightening is a rare phenomenon, but hardly in this series of small spectacular bomb like eruptions of Anak Krakatau from 24-26 October 2018:
Especially the later eruption in this video. The vulcano is about 800 meters high (but the number depends on the source). This gives an idea of the force with which matter is sent to heaven. The mountain apparently grows in height at at rate of 5 miters per year.

Agency last updated the volcano threat rankings in 2005
Twelve volcanoes increased in threat risk while 20 decreased
A new U.S. Geological Survey national volcanic threat assessment identified 18 volcanoes as a "very high" risk. The threat assessment reviewed 161 active volcanoes in the U.S. and divides them into five threat categories. In addition to the 18 very high threat volcanoes, the rest of the total includes 39 high threat, 49 moderate threat, 34 low threat, and 21 very low threat volcanoes.

While the vast majority of the active volcanoes are in Alaska and Hawaii, more than half of the highest threat category volcanoes are in Washington, Oregon or California. These west coast volcanoes were deemed very high threat because "explosive and often snow- and ice-covered edifices can project hazards long distances to densely populated and highly developed areas," according to the report.

These west coast volcanoes were deemed very high threat because "explosive and often snow- and ice-covered edifices can project hazards long distances to densely populated and highly developed areas," according to the report.

High threat volcanoes are identified as such due to their proximity to population centers, busy air traffic routes, economic infrastructure or due to increasing activity within the volcanic structures.

The threat assessment index does not identify which volcanoes are likely to erupt soonest, but rather it identifies risk areas. The most dangerous volcano is Hawaii’s Kilauea, which erupted earlier this year.

On a global scale, no U.S. city ranks among the world’s most at risk cities using Swiss Reʼs proprietary global volcano model. The Swiss Re model ranks Managua, the capital of Nicaragua, as the city with the highest expected substantial loss to its country-wide economy from a volcanic eruption. Among the top 15 highest ranked cities, 12 are located along ’the ring of fire’ -- an area of high volcanic activity -- which follows the edges of the Pacific Ocean.




Abstract
The caldera collapse of Deception Island Volcano, Antarctica, was comparable in scale to some of the largest eruptions on Earth over the last several millennia. Despite its magnitude and potential for far-reaching environmental effects, the age of this event has never been established, with estimates ranging from the late Pleistocene to 3370 years before present. Here we analyse nearby lake sediments in which we identify a singular event produced by Deception Island’s caldera collapse that occurred 3980 ± 125 calibrated years before present. The erupted tephra record the distinct geochemical composition of ejecta from the caldera-forming eruption, whilst an extreme seismic episode is recorded by lake sediments immediately overlying the collapse tephra. The newly constrained caldera collapse is now the largest volcanic eruption confirmed in Antarctica during the Holocene. An examination of palaeorecords reveals evidence in marine and lacustrine sediments for contemporaneous seismicity around the Antarctic Peninsula; synchronous glaciochemical volcanic signatures also record the eruption in ice cores spread around Antarctica, reaching >4600 km from source. The widespread footprint suggests that this eruption would have had significant climatic and ecological effects across a vast area of the south polar region.

Eruptive activity at the New Southeast Crater of Etna, 4-6 December 2018

https://youtu.be/lOxMPiyvxhA

This video shows short scenes of the current eruptive activity at the eastern mouth (locally known also as "puttusiddu") of the New Southeast Crater, at the top of Mount Etna. Strombolian explosions are noticed, often in short sequences of 5-10 events, and the emission of small lava flows from an effusive mouth distinct from the explosive one.

The shots were taken on the following dates and from the following locations:
00:00 - 00:32 on the evening of December 4, 2018 from Fornazzo (eastern side of Etna)
00:32 - 00:55 the afternoon of December 5, 2018 from Fornazzo
00:55 - 02:36 on the evening of 5 December 2018 from Santa Venerina (east-southeast side of Etna)

Note the rolling of numerous incandescent blocks with an effusive mouth, which in this perspective is slightly to the right of the explosive mouth. 02:36 - 03:32 on the morning of December 6th from Milo (eastern side of Etna)

... there was another event today although, the only video I found, comes with a ... flying object, they love to be around volcanoes ...

Abstract
Using volcanic sulfur dioxide emissions in an aerosol‐climate model, we derive a time series of global‐mean volcanic effective radiative forcing (ERF) from 1979 to 2015. For 2005–2015, we calculate a global multiannual mean volcanic ERF of −0.08 W/m2 relative to the volcanically quiescent 1999–2002 period, due to a high frequency of small‐to‐moderate‐magnitude explosive eruptions after 2004. For eruptions of large magnitude such as 1991 Mt. Pinatubo, our model‐simulated volcanic ERF, which accounts for rapid adjustments including aerosol perturbations of clouds, is less negative than that reported in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) that only accounted for stratospheric temperature adjustments. We find that, when rapid adjustments are considered, the relation between volcanic forcing and volcanic stratospheric optical depth (SAOD) is 13–21% weaker than reported in IPCC AR5 for large‐magnitude eruptions. Further, our analysis of the recurrence frequency of eruptions reveals that sulfur‐rich small‐to‐moderate‐magnitude eruptions with column heights ≥10 km occur frequently, with periods of volcanic quiescence being statistically rare. Small‐to‐moderate‐magnitude eruptions should therefore be included in climate model simulations, given the >50% chance of one or two eruptions to occur in any given year. Not all of these eruptions affect the stratospheric aerosol budget, but those that do increase the nonvolcanic background SAOD by ~0.004 on average, contributing ~50% to the total SAOD in the absence of large‐magnitude eruptions. This equates to a volcanic ERF of about −0.10 W/m2, which is about two thirds of the ERF from ozone changes induced by ozone‐depleting substances.
 
The guy in the video commented that he is noticing that there are a lot of people having the flu and, I have been noticing that as well, I wonder ... well, no .. I do not wonder that much, after reading a lot of eruptions and dust in the atmosphere, more like it, is as expected the increasing of flu around the globe, I would say and, is noticeable of what is mentioned above from c.a. post ...

Note that: Yellowstone's Steamboat Geyser erupts for 20th time this year -- Sott.net

https://youtu.be/1XYBg72LQNY
Hey guys. This is just a short video about the recent Steamboat eruption.
At 8:07UTC December 8, 2018 (1:07am MST December 8, 2018) Steamboat broke the all time record of 29 eruptions in one year, which occurred in 1964. Well let’s forget about 1964! The current all time record is now 30 eruptions in one year which occurred in 2018. It may erupt 2 more times before the year is over but the eruptions are getting smaller. Is it ending or is it saving the best for last?

Yellowstone Geyser: "Off the charts" with steam eruptions

Park officials have stated that Yellowstone volcano’s Steamboat Geyser is erupting at unprecedented rates, matching decades-old records for the amount of scolding water spewed from the ground. The Steamboat Geyser continues to be an enigma, one in which sparks fears of a massive supervolcano eruption.

The iconic Yellowstone volcano landmark is the world’s tallest and most active geyser but recent activity has gone off the charts. Yellowstone Volcano Observatory (YVO) geologists monitoring the supervolcano complex have noted almost weekly water eruptions from the geyser this year. The Steamboat geyser has been erupting every 7-10 day for the past six weeks.

According to the Express, during an eruption, it can spew near-boiling jets of water between 10 feet and 300 feet (3 meters to 91.4 meters) high. Eruptions typically last between one and four minutes and can come with intervals of two to five minutes at a time. Steamboat has so far erupted a total of 29 times in 2018, matching the record for most eruptions in one year from 1964. If the ongoing rate of eruptions continues, officials believe Steamboat will break the record in just days from now.

As of right now, the Norris Geyser Basin, where the Steamboat geyser is located, is closed to the public. However, after December 15 when the winter season begins in Yellowstone, you will be able to visit the geyser. According to KPAX 8, in order to get there, you’ll have to take either a snowcoach or snowmobile tour to Norris and then walk down snow-covered trails and boardwalks to see it.

In the meantime, Yellowstone National Park Spokesperson Morgan Warthin says the geyser’s eruptions are a pretty big deal for scientists. “You know, for scientists, they’re excited. I think everyone’s excited but in particular, the scientists because Steamboat is doing something that it hasn’t done for quite some time. So, for scientists it’s an opportunity to learn more about this really unique, and what was random, geyser that has now become not so random,” said Warthin.

Along with Steamboats eruptions, geologists have also been recording an increase in seismic activity. A total of 126 earthquakes rocket the park in November. “The largest event was a minor earthquake of magnitude 2.4 located 15 miles north of West Yellowstone, MT, on November 4, at 10:11 AM MST,” said YVO in a statement. Park officials say that this level of seismic activity is “common” and that there’s no need to be worried the supervolcano will erupt anytime soon.

Ovsicori warns that emanations will persist

Edgar Fonseca, editor / Edith Tropper / Ovsicori Photo

The Turrialba volcano awoke Wednesday with a constant eruption of ash that reached the vicinity of the Santamaría airport and delayed the departure of five flights, confirmed the authorities.

The flights affected this morning were: two from American Airlines, to Florida, two from Copa to Panama and one from Avianca to San Salvador.

Sporadic ash eruptions have remained in the volcano for several days and today is no exception, a report by Ovsicori confirmed.

The wind transported the ash northward during the early hours of the morning and then changed direction to take it to the southwest, he added.

The Central Valley will continue to receive ash fall. In a video they showed the images from 6:53 am to 9:15 am.

The eruption this morning had a column that rose to 500 meters above the height of the crater and 3840 meters above sea level, Ovsicori reported.

The fall of ash was reported in: Guadalupe. Sulfur odor is not reported, according to the report.

The emission of ash continues continuously and passively from at least yesterday to the end of the afternoon, with pulses sometimes denser. Because of the direction of the wind, it affects the Central Valley, said Geoffroy Avard of Ovsicori.
