Perhaps only days or months

26 July 2016 – Super volcanoes can eject thousands of cubic kilometers of magma and ash into the atmosphere in a matter of days or few months. That much ash could devastate the entire planet, blocking out light and heat from the sun for years or even decades.
Unfortunately, super volcanoes give very little notice before they blow their tops, a new study in PLOS ONE has found.
H/t reader squodgy:
“We mustn’t forget that the three concentrin rings showing the last three ‘supervolcano’ incidents at Yellowstone, have been on a reducing scale in that the last one was comparatively less in area than the second and so on, indicating that logically, should number four be triggered, whilst it will be a big issue, it SHOULD be of a much lower output than previously.”
SCIENTISTS have warned that if a super-volcano were to erupt, we would not have enough time to save the planet and humanity.
Experts state that we would only have about one year warning if a mega volcano were to erupt catastrophically, putting all life on Earth at risk.
A HUGE volcano in the US is on the brink of erupting, scientists have warned.
The violent Pavlof volcano, located in Alaska, erupted earlier this year, ploughing ash 37,000 feet into the air.
It is once again showing signs of activity, according to the Alaska Volcano Observatory (AVO), who said that the volcano is unpredictable and won’t give much warning if it is about to blow.
AVO research geologist Robert McGimsey said: “Pavlof is one of those volcanoes that can erupt without very much in the way of precursory activities.”
The AVO has increased the volcano warning code from green to yellow.

Long thought to be extinct, the Colli Albani Volcanic District, located just 19 miles (30 km) from downtown Rome, is waking up.
Using ground-based observations of rising land, earthquake swarms and steam vents along with satellite data to track Colli Albani’s activity, a team of researchers says the complex is overdue for an eruption.
The activity includes a four-year earthquake swarm that began in 1991, and more recently, a volcanic vent that opened near Rome’s Leonardo da Vinci-Fiumicino Airport in 2013,
A geophysics professor from the University of Iceland has warned people not to travel up Hekla volcano in South Iceland as it could erupt at any moment.
As reported by Icelandic news website visir.is (link in Icelandic), Hekla erupted regularly ever ten years or so from 1970 to 2000 – but has now been silent for sixteen years.
Have you noticed that our planet has begun to shake, rattle and roll? Over the past few days we have seen major volcanic eruptions in Costa Rica and Indonesia, and according to Volcano Discovery 40 volcanoes around the planet are erupting right now as you read this article. Meanwhile, earthquakes continue to shake the globe with alarming regularity. Just last week, Ecuador was hit by a magnitude 6.7 earthquake and a magnitude 6.8 earthquake in rapid succession. Overall, there have been more than 3,000 earthquakes of magnitude 1.5 or greater within the past month globally. So yes, I write constantly about the rapidly accelerating deterioration of our financial system, but the coming “collapse” is not just about money. I am convinced that we are entering a “perfect storm” in which a confluence of factors will absolutely cripple society and bring about changes that most of us would not even dare to imagine right now.

Small magnitude earthquake rates have been steadily increasing since March, reaching nearly 40 per week.
5 May 2016 – (Excerpts from USGS website) – Over the last 8 weeks, there have been over 130 earthquakes formally located by the Pacific Northwest Seismic Network and many more earthquakes too small to be located. The earthquakes have low magnitudes of 0.5 or less; the largest a magnitude 1.3. These earthquakes are too small to be felt at the surface.
“Is “The Big One” imminent?”
And it is quite interesting to note that in 1906 there were major earthquakes in Ecuador and Japan that preceded the historic San Francisco earthquake.
Of course most Americans have already heard about the magnitude 7.8 earthquake that hit San Francisco on April 18th of that year, but most people don’t understand that it came in the context of these other major quakes.
More than 25 million people live in the vicinity of Mt. Popocatepetl, including Mexico City’s 18 million residents. At 2:32 local time on Tuesday morning, the most dangerous volcano in Mexico roared to life in spectacular fashion, and this has many experts extremely concerned about what is coming next. Popocatepetl is an Aztec word that means “smoking mountain”, and historians tell us that once upon a time entire Aztec cities were buried in super-heated mud from this volcano. In fact, the super-heated mud flows were so deep that they buried entire Aztec pyramids. A full-blown eruption of Mt. Popocatepetl would be a catastrophe unlike anything that modern Mexico has ever experienced before, and considering what has been happening in Ecuador, Japan and at Yellowstone over the past week, I believe that there is great reason for concern.
The eruption of Mt. Popocatepetl very early this morning took residents of the area very much by surprise. The following is how one Mexican news course reported the news…
The public seismographs which monitor earthquakes in and around the Yellowstone super-volcano are presently OFFLINE, and the public is not presently able to see seismic activity there.
Being able to see what is taking place in and around Yellowstone is of great interest to many people because if there is a sudden flurry of earthquake activity, it COULD — but not necessarily — signal a pending eruption.
Since Yellowstone is the only “super volcano” on the North American continent, and is VERY geologically active, if an eruption were to actually take place, the western two-thirds of the United States would POTENTIALLY be hit with volcanic ash and a severe disruption of life.
So why are the public seismographs from the US Geological Survey (USGS) OFFLINE (to the public) today? No one is providing any answers.
Even more peculiar, the privately-funded seismographs from the University of Utah . . . are also OFFLINE (to the public) right now. No one is providing any explanation for this either.
After poking around to various folks involved in the University of Utah Seismic Center, one person at that facility “quietly” e-mailed us a single graphic image which gave us pause:

“Looks like something could be de-stabilising the crust.”
Two volcanoes are erupting on the Pacific “Ring of Fire” indicating a massive build-up of tectonic stress on the west coast of North America. It began at 4:18 PM Alaska time (8:19 PM Eastern Time) when the Pavlov volcano on Alaska’s Aleutian Island Chain, blew ash, stone, dirt, smoke some four MILES into the air before lava began seeping out.
The US Geological Survey mentioned that the Pavlov Volcano, around 600 miles southwest of Anchorage, has erupted at 4.18pm local time.
The agency affirmed that the eruption led to tremors on the ground. It has raised the volcano alert level to ‘warning’ and the aviation warning to ‘red’. The USGS said that the Pavlov Volcano has 40 known eruptions.
Last time, it erupted in 2013 and at that time, the plumes rose 27,000 feet. Considered to be one of the most consistently active volcanoes in the Aleutian arc, other eruption on the Pavlov volcano has generated plumes as high as 49,000 feet.
The Alaska Volcano Observatory said, “As of 4:18 pm AKDT … ash was reportedly moving northward from the volcano. Seismicity began to increase from background levels at about 3:53 pm … with quick onset of continuous tremor, which remains at high levels”.
The volcano is around 7km in diameter and has active vents on the north and east sides close to the summit. Eruptive activity is characterized by sporadic Strombolian lava fountaining that continues to take place many months.
A report published in the ADN News said, “A volcano on the Alaska Peninsula has stirred with new activity this weekend, with volcanologists reporting an eruption Sunday afternoon that sent ash 20,000 feet into the air. The Alaska Volcano Observatory said on its website that the alert level had risen to warning and the aviation color code to red for the Pavlof Volcano, on the Alaska Peninsula about 30 miles northeast of the community of King Cove, and 36 miles from Cold Bay. The fresh eruptions, reported Sunday afternoon, raised the alert level from normal and the color code from green.
In a report published by the KTUU News, The Aviation Color Code has been raised to red and the Volcano alert has been raised to Warning.
Pavlof Volcano is located on the Alaska Peninsula about 37 miles away from Cold Bay and almost 600 miles away from Anchorage. “With over 40 historic eruptions, it is one of the most consistently active volcanoes in the Aleutian arc,” officials wrote. “Eruptive activity is generally characterized by sporadic Strombolian lava fountaining continuing for a several-month period.”
As per the research paper published by the study team, The USGS has raised the volcano alert level to “Warning” and the aviation warning to “Red.” The agency says the volcano, which is about 4.4 miles in diameter, has had 40 known eruptions and “is one of the most consistently active volcanoes in the Aleutian arc.” The USGS says that during a previous eruption in 2013, ash plumes rose 27,000 feet. Other eruptions have generated ash plumes as high as 49,000 feet.
Volcano-alert notifications are produced by Volcano Observatory scientists and are based on analysis of data from monitoring networks, direct observations, and satellite sensors. They are issued for both increasing and decreasing volcanic activity and include text about the nature of the unrest or eruption and about potential or current hazards and likely outcomes. Scientists describe a volcano’s status using the alert levels and color codes and issue different types of notifications to address specific information needs. All notifications are publicly available.
Volcano Activity Notice (VAN)-Announces alert-level changes or significant volcanic activity within an alert level; covers all volcanic hazards-lahars (volcanic mudflows), lava flows, ashfall, airborne ash, pyroclastic flows.
Hours later, the he Popocatepetl volcano which is located 70 kilometers from Mexico City, showed signs of life. That became clear when an ash cloud of up to two kilometers was put away the air. People who live nearby, are advised to cover their mouth and nose with a damp towel. In addition, no one within twelve kilometers arrive at the volcano for safety reasons. Some sixteen years ago, the Popocatepetl erupted for the last time out, requiring as many as 40,000 to be evacuated. Mexico has 3,000 volcanoes, of which 14 are active.
The occurrence of these two volcanic eruptions signals the Pacific Tectonic Plate, which basically “floats” is now pressing heavily against its northern and southeastern boundaries. That’s causing pressure to be released from the two volcanoes. It also means there must necessarily be tremendous pressure along the eastern boundary, pressing-up against California. The potential for this to trigger a large earthquake along the US west coast is therefore greater.

The activity of the lava lakes in Masaya’s Santiago crater is increasing. According to INETER, volcanic tremor remained high and Real-time Seismic Amplitude Measurement (RSAM) values were at high to very high levels during February 20 – March 1, 2016.
On February 23, small explosions ejected spatter onto the crater floor. Volcanologists observed active lava lakes in all three vents on the crater floor, and noted that the inner walls of the crater were being eroded due to the lava lake and a new vent was forming on the SE part of the crater floor.
Last August, in a hilarious example of bad timing, Japan restarted its first nuclear reactor since the Chernobyl redux at Fukushima just as a nearby volcano was set to erupt.
Sakurajima, one of the country’s most active volcanos, erupts almost constantly, but experts warned the next eruption could be “the big one”, so to speak.
The Popocatépetl volcano, just 35 miles from Mexico City and only 20 miles from nearby city Peubla sent a mile high plume of ash into the air, putting thousands of people living within 10 miles of it on a yellow alert to be ready to evacuate should activity increase.
The Mexican capital is the world’s fourth most populated city and home to 20 million people, while Peubla has more than 6 million people living there, and all could be at risk in both cites in the event of a catastrophic eruption.
The volcano alert follows fears earlier this month that a second large volcano in Mexico – the 3,850 metres-high Colima in western Mexico – could be about to face a large scale eruption for the first time in 100 years.
Popocatépetl last saw a major eruption in 2000, but early warnings saw 41,000 people evacuated in advance, averting a major disaster.
Powerful deep Arctic Ocean geological heat flow forces are melting the ice, says geologist James Edward Kamis.In an article entitled “Heat From Deep Ocean Fault Punches Hole in Arctic Ice Sheet,” Kamis punches his own holes in the “humans-are-melting-the-ice”chorus.
“A very interesting high temperature and low salinity hole has just been punched in the sea ice … directly above the deep ocean Gakkel Ridge Rift / Fault System,” wrote Kamis in early November. (The event Kamis is referring to took place on October 12, 2015.)
Massive amounts of heat pulsing from the earth
The Gakkel ridge is a gigantic chain of underwater volcanoes snaking 1,800 kilometers (1,100 miles) beneath the Arctic Ocean from the northern tip of Greenland to Siberia.
