Is the number of volcanic eruptions worldwide increasing?
Yes, answers Michael Snyder in this startling article.
During the 20th century, there were a total of 3,542 volcanic eruptions globally. That works out to approximately 35 eruptions per year. That may sound like a lot, but according to Volcano Discovery there are 36 volcanoes erupting around the world right now. In other words, the number of volcanoes erupting as you read this article is greater than the 20th centurys yearly average.
And all of this is part of a larger trend. In 2013, we witnessed the most volcanic eruptions worldwide that we had ever seen in a single year, and 2015 is already threatening to be another one for the record books. All over the planet, volcanoes that have long been dormant are beginning to wake up, and this is greatly puzzling many scientists.
Snyder goes on to discuss the consequences of a VEI 7 or VEI 8 eruption, wherein he envisages the Earth being flung back into a pre-civilisation state.
The truth is that volcanoes are far, far, far more of a threat to our climate than human activity is, says Snyder. All throughout history, volcanic eruptions have instantly changed the climate in a dramatic way.And that would profoundly affect agriculture.
Global food production is just barely keeping up with global food demand, Snyder points out. In fact, in some years the world actually eats more food than it produces. Global food reserves are at perilously low levels, and so a (volcanic) year without summer would be absolutely cataclysmic.
Doesn't matter. They are counting current eruptions, not year to date ones. Comparing current eruptions against a yearly average is a meaningless comparison. It doesn't take into account how long eruptions last. It's bad math.

This COULD happen in our lifetimes. Odds are, it won't. Volcanos range from the "safe" Hawaii types of volcanos to Yellowstone and Toba (VEI-8).
We've had a handful of major volcanic eruptions in our lifetimes. If you take away the "locally" major eruptions that cause casualties due to proxcimity (like Mt Pelee), then it's even rarer.
Large volcanic eruptions the size of a Mt St Helens (1980) are rare. Mt. St Helens was VEI-5. There were 12 VEI-5 or larger eruptions in the 20th century, 1 VEI-5 or larger in the 21st century, and 8 or 9 VEI-5 or larger eruptions in the 19th Century. Usually it will take a VEI-6 to significantly affect climate.
In my lifetime, there was one VEI-6. Mt Pinatubo. Mt Hudson was VEI-5 around the same time as Pinatubo possibly causing amplified effects. The other 20th century VEI-6 were in the early 1900's. I'm not sure about climate effect.
In the 1800's the known VEI-6 was Krakatoa and the known VEI-7 was Tambora (Year without a summer).
There is believed to be maybe six VEI-7 eruptions during "semi-modern civilization" going back to Santorini (Mionans). That goes back 3700 years.
If we get another Tambora or Santorini, we're in trouble. If Yellowstone or Toba sized eruption happens (last one 70000+ years ago), we're screwed. Is it likely to happen in our lifetime? No.
“Volcanos happen. Numbers?? There is no standard predictor. Happens when it wants to. Man has zip to do with it.”

You forgot to include the Cascadia fault that runs along the coast of n. CA up to WA!
Based on the evidence in the rocks!
Given the political venom the D.C. elite throw at Americans in the breadbasket is it reasonable to think they would act like the English did in Ireland during the potato famine? Can you imagine Americans starving to death while the parasites in Washington ship grains and produce to the highest foreign bidder? Sadly, I can.
That’s pretty awesome.
Snyder's right...
“We need to plug them up with used tires and junk cars and Muslims.”
Or at least use the tires for volcano pranks on the public!
One of the greatest April fool’s pranks EVER, orchestrated by Porky Bickar
http://www.sitka.com/Porky/porky.htm
From the Top 100 April Fool’s Day Hoaxes of All Time in which Porky’s prank was #16:
1974: Residents of Sitka, Alaska were alarmed when the long-dormant volcano neighboring them, Mount Edgecumbe, suddenly began to belch out billows of black smoke. People spilled out of their homes onto the streets to gaze up at the volcano, terrified that it was active again and might soon erupt. Luckily it turned out that man, not nature, was responsible for the smoke. A local practical joker named Porky Bickar had flown hundreds of old tires into the volcano’s crater and then lit them on fire, all in a (successful) attempt to fool the city dwellers into believing that the volcano was stirring to life. According to local legend, when Mount St. Helens erupted six years later, a Sitka resident wrote to Bickar to tell him, “This time you’ve gone too far!”

I agree, ‘cause we’re all gonna DIE!
Time. Could be today, could be 100 years from now, could be 1000 years from now. That mean old time.
Once again, just because things have always been a certain way does not mean that they will always be that way.
You think? I was once young, now I'm old. A lot of things changed, darn it.
Whatever happens, we are powerless so why worry about it? There's all this fear stoked by liberals because of nature doing its thing. Knowledge of the why and how, is a good thing. Fear of nature is a bad thing. I'm in awe of the power of nature and God's creations. I fear the doings of liberals more than of nature. If it all blows up, then we'll deal with the aftermath. In the meantime let's take one day at a time and live our lives. And put a stop to liberals and their attempts to manipulate nature without understanding why it does what it does.
Wow, that is one hell of a story.
They’d lock him up for life if he did that today.
There just is not a sense of humor left in todays world.
Now just a bleepin second.
and that's not the worst part...we're all gonna die.....AGAIN!
That too, you are correct.
Considering that the average inter-glacial is about 11,500 years and we’ve been in one for some 11,800 I think the signs of us going back into the two million year deep freeze are there based on volcanic and seismic data, the decreasing strength of the Earth’s magnetic field, the increase in the movement of the Earth’s north pole from five miles per year around 1850 to 35-40 miles per year currently, and other factors.

The highest I have climbed was the summit of Cerro Aconcagua in the Argentina Andes. Climbed by the difficult Polish Glacier Route. The summit is just under 23,000 ft. From start to finish this climb took 21 days.
