General Volcanic Activity Thread!

[Methuselah]

can't see how a slowdown in solar activity would effect volcanism on earth without some increase in gravitational forces from the sun ??.

And that would need the Sun to abruptly lose an unusually large amount of mass. A CME the mass of Mercury ought to do it!

and would we be in position to care with such an ejection ..

We'd be able to see an Aurora. But we mustn't allow such far-fetched notions to reach the citizens of Shirley!

Shirley Massachusetts , they might be shaken !!.

Etna went boom yesterday not from the se crater but from vogerine good pic here http://www.theguardian.com/world/2015/dec/03/sicily-mount-etna-voragine-crater-erupts-lightning

Meanwhile Nicaragua’s Momoto erupted for the first time since 1905.

Another stunning shot of Etna volcano eruption last night. WOW notice the lightning inside the eruption column, spreading into an anvil cloud!

Amazing glad it was quiet when I was up there !!

Another amazing image of the eruption of Etna.

Volcanic tremor graphs (taken from the Osservatorio Etneo web site http://www.ct.ingv.it/en/tremore-vulcanico.html )  may be indicating that it's about to blow again?

Any vague glimmer of hope Etna going boom was big enough to encourage cold weather?

Nope it was just a little sneeze.

Damn and blast it! Guess I'll just have to carry on dreaming then, hey ho.

Went again yesterday 3rd eruption from same crater

[The PIT]

Looks like it's erupting again right now.

[The PIT]

ERupting again can't see which vent maybe one low on the new se crater

[Snipper]

So what sort of eruption would make the Paris agreement somewhat redundant, apart from the world needs better housekeeping anyway?

What in the past?  Santorini?

Krakatoa ,toba ,pinatubo ,mammoth lakes and   popocatepetl are just a few to screw up their hubris...

Out of that list Toba and Mammoth lakes only had a more prolonged climate change.

The eruption of Laki in Iceland brought a brief change of climate to Europe and parts of the states.

[Michele Grilli]

Stars form due to the weaker force but more widespread in the universe: the
severity.
The universe is dotted with huge piles of dust and gas, called "nebulae"; in
Following their spontaneous movements sometimes they begin to rally around nuclei
heavy, inevitably, begin to exert a gravitational pull on
rest of the dust and gas surrounding, attracting just as the Earth exerts
a gravitational pull on the apple falling from the tree or on us that
we remain with our feet on the floor instead of getting lost in space. Here it is
then triggered the mechanism that can lead to the birth of a star.
The gravitational pull exerted by these gas concentrations, mainly
hydrogen (the element by far the most abundant in the universe), with the passing of
hundreds of thousands of years and then become so strong as to attract a lot of material;
so much matter means so much weight, so much compression, then an increase
soaring temperatures (a gas is compressed more it is hot, due to friction
stronger which is exercised between the molecules that compose it. It is the same mechanism
which raises the temperature of the air in conditions of Foehn, ie wind
descendant that compresses air masses falling down the mountain slopes!
While the mechanism contrary, the rarefaction of the gas-air with a relative decrease
Thermal, is that which, through different processes, leads to the condensation of the clouds
or to the phenomenon that in proportion ago on average colder than the ground!).
When the temperature of the proto-star has reached a particularly
high, here they are enough to trigger the so-called mergers thermo-nuclear:
"Thermo" because it depends on the heat reached, "nuclear" because affecting the nuclei
of hydrogen atoms that, being the most massive of the atoms, they begin to
scindersi then transformed into helium, gas slightly heavier.

Mt Helens showing signs of restless as a new earthquake swarm starts. https://volcanoes.usgs.gov/observatories/cvo/cvo_news_archive.html

The depth plots are the most interesting. Before the last eruption there wasn't any clear injection of magma from depth. So something in the next few years???

The sooner the better because I am bored.

Been fairly quiet lately.

Ruapehu in new Zealand showing signs of unrest with the alert level raised to 2 after continuing swarms and the crater lake continued heating.

MT cleveland is orange alert after a some explosions during the last week. https://www.avo.alaska.edu/

That could mess up the ski season for Whakapapa and Turoa! (Due to open in about 7 weeks) http://www.mtruapehu.com/

Both are on Ruapehu and offer some very good skiing.....though don't expect lava would do much for the pistes. When I've skied there I've always been conscious of the volcanic alarm tests though never been wholly convinced by the advice...... "move to higher ground and out of the valleys"
