Japan - Mt Aso eruption

[Bob]

Mount Aso is the largest active volcano in Japan has erupted, and is among the largest in the world.

It stands in Aso Kujū National Park in Kumamoto Prefecture, on the island of Kyushu.

Its peak is 1592 m above sea level.

thick black smoke and ash more than a mile into the air and disrupting flights, authorities said.

About 100 tourists and other visitors were in the vicinity of Aso, a popular hiking destination, at the time of the eruption, but they were quickly whisked away to safety, Japan's NHK news agency reported.

A ropeway transit station more than a half-mile away was covered in volcanic ash. Aso police station told NBC News that about 20 people who were inside the station at the time of the eruption were safely evacuated.

Aso erupted without warning about 9:43 a.m. (8:43 p.m. Sunday ET) in one of the Nakadake craters at Mount Aso, on the southwestern island of Kyushu, the Japan Meteorological Agency said. The agency issued a level 3 alert, warning people to stay away from the area.

Sadayuki Kitagawa, the agency's senior coordinator for volcanic affairs, warned that a second eruption was possible "with possibility of volcanic rocks landing in an area over a 1-kilometer radius," or about six-tenths of a mile. He urged people to be vigilant for flying rocks and ash within a 2-kilometer radius.

Aso last erupted in April, sending smoke almost 5,000 feet into the sky. No one was injured at that time.

I wonder if this has to do with the waves of energy some are predicting? The Ruiner said in July that there was a wave of organic energy coming from somewhere out there that had already changed other planets. Lily Earthling Kolosova states that the source of the energy is from the Earth itself and that is intended as nurturing waves and that these waves have been happening for quite some time. I follow Dutchsinse on facebook and he had been tracking an "uptick" in the frequency and severity of earthquakes in recent years. He has been doing a great job of exposing weather phenomena in the past. https://www.youtube.com/user/dutchsinse

He also tracks microwave pulses that may be manmade as well as the frequency of earthquakes worldwide. He also talks about fracking as a cause of earthquakes. https://www.youtube.com/watch?v=isAYbGyTCqM isAYbGyTCqM

one also has to wonder if there is any kind of warfare going on, but there does seem to be increases activity going on worldwide.

Background:

The "volcano" is made up of surrounding cones -


http://volcano.si.edu/volcanoes/region08/kyushu/aso/4002aso34f.jpg

The volcano consists of 12 calderas. Asosan, the largest and most active, has had many small eruptions in the past few thousand years, including many witnessed eruptions.

Asosan is located on the S of the main island of Japan (Honshu) on the island of Kyushu.

The Aso caldera, 25 km north-south and 18 km east-west in diameter, was formed by four gigantic pyroclastic-flow eruptions from approximately 270,000 to 90,000 years ago.

Post-caldera central cones were initiated soon after the last caldera-forming eruption, producing not only local lava flows but also voluminous tephra layers which fell far beyond the caldera.

Nakadake Volcano, which is the only active central cone of basaltic andesite to basalt composition, is one of the most active volcanoes in Japan.

Does this eruption signify anything in particular? Are global volcanic events on the increase? Let's look at it scientifically, and get to the root of "reporting" of activity increasing.. Think MEDIA, think ability to quickly report, and log those reports.. Statistics increase in frequency when the ability to get the data out increases.. REPORTS increased but not ACTIVITY overall..

Are volcanic eruptions on the rise?

Not according to Lee Siebert, director of the Smithsonian Global Volcanism Program (GVP). Charged with documenting, analyzing and disseminating information about Earth's active volcanoes, the GVP boasts 40 years of data to indicate it's business as usual under the crust.

"If you plot data from the last 200 years, there's a clear increase in the number of eruptions over time," Siebert said, "but that's not a function of the actual number of eruptions but rather due to reporting effects."

Specifically, the GVP found that the increase in volcanic eruptions paralleled the rise in global population. It paralleled human encroachment of volcanic areas and improvements in communication technologies. Think of it as the "if a tree falls in the forest" effect. With more people around, and better technology, it became harder for a volcanic eruption to go unnoticed.

"If you plot the data over time, you do see peaks and valleys with an overall upward trend," Siebert said, "but a lot of those specific peaks or troughs can be attributed to individual reporting events. For example, there are prominent troughs that correspond to World War I and World War II, times when people's attention was focused on other issues."

During those periods of global strife, Siebert said, we simply didn't record eruptions with the same regularity. Conversely, reporting jumped following the dramatic eruptions of Krakatoa in 1883 and Mount Pelée in 1902. Sensitized by such intimidating examples of volcanism, the world took greater notice of smaller occurrences, at least for a time.

Observation bias aside, global volcanism has remained steady throughout recorded history. You have to view the planet from a geologic perspective, spanning millions and billions of years, to glimpse any major changes — or pinpoint an eruption higher than a seven on the Volcanic Explosivity Index (VEI).

"Those are the Yellowstone-type eruptions, sometimes referred to as 'supervolcanoes,'" Siebert said. "None of those have occurred in historical time."

Fire and Ice
So what typically causes global volcanism to increase? Nothing short of titanic movements in the planet's crust, according to Jacob B. Lowenstern of the United States Geological Survey.

The theory of plate tectonics divides the surface of the Earth (or lithosphere) into an interconnected puzzle of gigantic sections, or plates. Sometimes these plates rub against each other at transform boundaries. Other times, however, subduction occurs, a process that pushes one plate under another and, consequently, raises mountains, stirs earthquakes and generates volcanic activity.

"The tectonic plates are driving volcanism for the most part," Lowenstern said. "And over geologic time, those processes are turning on and off. Subduction zones begin and end. Hot spots are generated and thrive for millions of years and then just stop. So as a result of those effects, you get increased volcanism or decreased volcanism in certain areas and even globally."

The formation and melting of glacier ice can also theoretically affect volcanism. But to find a possible example of this, Siebert said, you'll have to look back to the beginning of the Holocene epoch 10,000 years ago.

"There were depressions in the Earth's crust due to glacial ice during the ice ages," Siebert said. "That ice melted back, resulting in a rebound effect that has been related by some to an increase in volcanic eruptions during that time."

Still, Siebert and Lowenstern stress that the relationship between melting glacier ice and increased volcanism is far from cut-and-dry.

"It's a lot more complicated because ice is melting in one place, and the water is going somewhere else," Lowenstern said, "So you might have a decrease in pressure in the northern latitudes as a result of ice melting, but you also might have an increase in the ocean depths in the south that might keep magma from erupting. And even then, it's not a simple relationship between increased pressure and decreased volcanism."

Several other factors also influence the planet's volcanism, some of which scientists don't fully understand. So while a few studies predict future climate change may generate a rebound effect, climate typically plays an indirect role.

"Volcanism typically influences climate," Lowenstern said, "not the other way around."

The trend over the full period is basically flat, and while there was a slight increase on average from about 1997 to 2008, this is balanced by a decline in recent years.

[..] reasonably comprehensive reporting of global volcanism began in the 1960s. Note that the number of confirmed erupting volcanoes has leveled off between 50 and 70 per year through the past four decades, and a linear regression line through the data indicates that volcanism has been virtually constant.

Has solar x-ray output (from flares) contributed to the eruption? Not apparently:

Current x-ray flare activity - NIL, hardly any measurable spiking output; if anything EXTREMELY non-event-like. NADA/ZIP.


http://chanlo.com/images/14sept2015.jpg

What about particle stream energy from solar coronal holes? Over the last two weeks particle activity has been lighting up the Auroras over the North and South Poles. The CotoPaxi volcano in Ecuador has been progressively DIMINISHING in overall output. (threads about the Solar Coronal Holes, and CotoPaxi volcano exist by this author in the Forum - see the appropriate subforums)


http://chanlo.com/images/13sept2015wind.jpg

The solar wind has been increasing and decreasing, oscillating, primarily from the solar coronal hole particle emission - this has been bouncing the geomagnetic fields up and down - has this been any trigger to the Japan Aso volcano eruption? Although this bouncing has been happening, apparently it has not changed (if anything decrease in activity has been noted) the emission of the CotoPaxi Volcano in Ecuador.

Great thread Bob, well thought out presentation, lots of good information from reputable sources.

I disagree with the tenet that there is no increase in volcanism world wide. The arguments presented are fickle, reality says differently.

Where is the consideration of the Earths magnetic fields in respect to the activities of global High Energy Physics, Tokamak reactors and indeed CERN. Where is the reference to the "hot" anomalies of the Pacific, el Nino and off the coast of California. Why are these excluded from the experts consideration.

Providing the reader with professional looking graphs with "experts" backing them is the same method Al Gore used to promote the Climate Scam and the aberration of science presented as fact by the Oxford meteorological Centre.

I believe there is an increase in technological interference by man in these events and based on evidences already available, I expect to see a greater increase in these massive geological and meteorological disasters especially around the Pacific rim. I am genuinely concerned for the western seaboard of North America.

Nevertheless, this is a superbly presented suite of information specific to Mount Aso and has been most interesting by its focus.

No more so then those of us living here! :P

This is roughly the distance I see Mt. Rainier/ Mount Tahoma from.

Dutchsinse's research video (above) coincides with a small 3.2 quake centered directly under White Island (active volcano, approx 30-50 miles East of Tauranga/Whakatane coastline in the Bay of Plenty). As a kid, I remember it erupting badly back in the late 60's; it caused a Tsunami significant enough to damage Beach front properties and batches right across the Waihi Beach area. If it really blew, then we would be looking at something fairly major across the East Coast.

On a slightly different note, TWO volcanos began erupting in Mexico over the last week. The one to watch for is Mt Popocatepetl which is North America's 2nd largest volcano - and it sits right on top of the San Andreas faultline.

Colima Volcano, located in southwest Mexico, is spewing fresh smoke and ash in a series of small eruptions, according to reports Saturday. And, about 310 miles away, another volcano, Popocatepetl, has also erupted.

The Colima volcano has been rumbling since July 10, when its last major eruption occurred. Also known as the Fire Volcano, Colima shot ash over 2,000 meters into the air and cloaked local villages with dust, RT.com reported. Local authorities are monitoring the volcano’s activity and have reportedly put an emergency plan into action.

Though Colima has been touted as the most active volcano in Mexico and in North America, it has only erupted about 40 times since the 16th century.

Meanwhile, the Popocatepetl Volcano -- located in southern states of Puebla and Morelos -- has recorded 12 exhalations, mostly of gas and vapor, according to Sky News. Nicknamed El Popo, Popocatepetl came back to life in 1994 after about 50 years of inactivity. Since then, the volcano has erupted at irregular intervals.
