The biggest concern with an eruption the size of Yellowstone is ashfall.
The force would shoot ash into the atmosphere up to 30 kilometres high where the easterly jetstream would carry it as far away as Europe within three days.
The volcano would also eject sulphuric acid into the air forming an aerosol that remains in the atmosphere for years, screening out sunlight, causing global temperatures to drop and killing crops for years afterward.
Even 1 millimeter of ash will close airports, cause damage to vehicles and houses, andcontaminate water supplies.
SCIENTISTS have warned the world is in “volcano season” and there is up to a 10% chance of an eruption soon killing millions of people and devastating the planet.
Over the past week, our planet has been hit by large earthquake after large earthquake, and according to Volcano Discovery there are 38 volcanoes around the world that are erupting right now.
We have seen a dramatic spike in global seismic activity that is unlike anything that we have seen in ages, and that is why what is going on at Yellowstone is so incredibly alarming.
Geologists tell us that a full-blown eruption of the Yellowstone supervolcano would have up to 2,000 times the power of the Mount St. Helens volcanic eruption of 1980, and approximately two-thirds of the country would immediately become uninhabitable.
As you will see below, there are signs that something big is getting ready to happen at Yellowstone, and if it does erupt all of our lives will be permanently changed forever.
I want to share with you some footage from Yellowstone that was recorded on Thursday night. In this video, it appears to be as bright as day even though it is the middle of the night, you can see a whole host of geysers steaming violently, and Old Faithful just keeps going off over and over…
This stunning footage was posted by a YouTube user known as Kat Martin , and the following is what she had to say about the video that you just saw…
There are places steaming I have never seen steam before….and also note that the bright ground is back. There are no shadows, so it is not from above! As you know the cameras were froze up last night, so we could not see what was going ….or so we thought LOL…I found a way.
Somehow (don’t ask me how), the Geyser Observation Study site was able to capture the ENTIRE night with NO freeze ups and cutting in and out….how is THAT? Anyway, I got it and slowed it down so you can see better. Old Faithful had weird seismos last night, and was going off constantly.
But it wasn’t just that one night.
So what does this mean?
I don’t know, but watching that footage definitely got my attention.
And it is interesting to note that just a few weeks ago the Shoshone River changed color and started boiling without any warning whatsoever…
The Shoshone River, near Yellowstone National Park, suddenly and without warning started boiling, changed color and began to emit a sulfuric odor on March 25. Nearby witnesses wondered if they were “all going to die.”
The current consensus among geologists and other experts is that a portion of the Shoshone River began to boil, located near Cody, Wyoming, and a new Yellowstone vent has opened up.
As Mysterious Universe reports, the boiling river near Yellowstone runs just east of Yellowstone National Park. It is close enough to the park and super volcano to be a “canary in a coal mine” as it relates to unusual geothermic events.
The event was initially recorded by Dewey Vanderhoff, a photographer who spotted the Shoshone River near Yellowstone boiling and noted other bizarre features in the river.
When a river located above a supervolcano that could wipe out most of the country starts boiling, you would think that would make headline news all over the nation.
But it didn’t.
It would be exceedingly difficult to overstate the potential danger that Yellowstone poses to the United States. Other than an extremely large asteroid or meteor, it is hard to imagine any natural disaster that would pose a greater threat. The following comes from an excellent article by Steve Elwart…
The Yellowstone Caldera, or cauldron, sits on top of North America’s largest volcanic field. Four hundred miles under the Earth’s surface is a magma ‘hotspot’ that reaches up to just 30 miles below ground level before spreading out over an area of 300 miles across three states.

Over all this sits the volcano.
While most scientists believe the probability of a major eruption is very small, there are signs that have some analysts worried, and most agree the volcano holds catastrophic potential.
It could blast 240 cubic miles of ash, rocks and lava into the atmosphere, rendering about two-thirds of the nation immediately uninhabitable, according to some estimates, and plunge the world into a “nuclear winter.”
That certainly does not sound good.
And as I mentioned above, volcanic activity all over the planet is rising. 38 volcanoes are erupting at the moment, and it seems like we hear about another new eruption almost every day now.
But let us hope that Yellowstone does not erupt any time soon.
There are approximately 3,000 earthquakes in the area around Yellowstone every single year, so it is a very seismically active region. In the event of a full-scale eruption of Yellowstone, virtually the entire northwest United States will be completely destroyed.
Basically everything within a 100 mile radius would be immediately killed, Salt Lake City would literally be toast, and almost everyone and everything in Denver would be dead in short order.
Further away, volcanic ash would rain down continually for weeks. Those foolish enough to step outside would quickly discover that the ash turns into a substance similar to cement in the lungs, and many would die from suffocation.
The amount of volcanic ash released by Yellowstone would be almost unimaginable. In fact, it has been estimated that a full-blown eruption would dump a layer of volcanic ash that is at least 10 feet deep up to 1,000 miles away.
Food production in America would be almost totally wiped out, and the “volcanic winter” that would result from a Yellowstone eruption would dramatically cool the planet. Some have projected that global temperatures would decline by up to 20 degrees.
In the end, the death, famine and destruction that we would experience would be vastly greater than anything that we have ever seen in the history of western civilization.
So yes, there is reason to be concerned that weird stuff is going on at Yellowstone right now.
The world’s most dangerous active volcanoes include Yellowstone, Mount Vesuvius in Campagnia, Italy, and Popocatépetl i near Mexico City.
If any of them or other massive volcanic peaks suffered a major eruption the team said millions of people would die and earth’s atmosphere would be poisoned with ash and other toxins “beyond the imagination of anything man’s activity and global warming could do over 1,000 years.
The chance of such as eruption happening at one of the major volcanoes within 80 years is put at five to ten per cent by the experts.
There are already fears that Yellowstone could blow any time within the next years on a scale that would wiped out the western USA and affect the course of global history.
The report – “Extreme Geo-hazards: Reducing the Disaster Risk and Increasing Resilience,” warns global government’s preparations for such happenings are virtually non-existent.
It said: “Although in the last few decades earthquakes have been the main cause of fatalities and damage, the main global risk is large volcanic eruptions that are less frequent but far more impactfull than the largest earthquakes.
“Due to their far-reaching effects on climate, food security, transportation, and supply chains, these events have the potential to trigger global disaster and catastrophe.
“The cost of response and the ability to respond to these events is beyond the financial and political capabilities of any individual country.”
Hence extreme volcanic eruptions pose a higher associated risk than all other natural hazards with similar recurrence periods, including asteroid impacts.
The report looked at other major geo-hazards facing the globe, including earthquakes, drought, asteroids floods, tsunamis, hurricanes, avalanches and wildfires.
Large earthquakes and tsunamis have happened more in the last 2,000 years, meaning there was better preparedness.
The report concluded: “Volcanic eruptions can have more severe impacts through atmospheric and climate effects and can lead to drastic problems in food and water security, as emphasized by the widespread famine and diseases that were rampant after the Laki 1783 and Tambora 1815 eruptions.
“Hence extreme volcanic eruptions pose a higher associated risk than all other natural hazards with similar recurrence periods, including asteroid impacts.”
The eruption of Tambora on Sumbawa, Indonesia killed about 100,000 people, but ash clouds meant there was no summer the following year and it was “one of the most important climatic and socially repercussive events of the last millennium,” the report said.
The earlier Icelandic event killed close to 10,000 instantly, but the long-term, effects wiped out 25% of the population and were felt across the planet.
A famine in Egypt reduced the population by one sixth, 25,000 died in the UK from breathing problems and there was worldwide extreme weather.
Similar scale events today would be much more catastrophic, the team warned, due to
much bigger populations, global travel and food chains and reliance on technology.
Worryingly, scientists say research over the last 300 years of volcanic activity shows we are currently in a “volcano season” meaning increased activity.
Volcanoes are also more likely from November to April in the northern hemisphere when ice, rain and snowfall can compress the bedrock.
