Ash fall out to distances of hundreds of kilometers can be many inches thick, according to simulations carried out by USGS scientists. Besides these local implications, volcanic eruptions that expel massive amounts of ash and gas into the atmosphere can have global impacts.
These aerosols reflect the heat of the sun back out into space, which can cause cooling of up to several degrees worldwide if the eruption is large enough. In Europe and North America, 1816 was known as the “year without a summer” because of global cooling caused by the 1815 eruption of Tamara, in Indonesia.
We can be confident of this because there have been two massive explosions while humans were present on Earth, and both of these were actually larger than Yellowstone's most recent cataclysmic eruption. The geologic record doesn't contain any information about the New Zealand eruption and its impact on humanity, although climate must certainly have been affected.
Evidence from archeology, however, suggests that humanity did not suffer greatly from the effects of the Toby eruption. For example, studies from hominid (but not necessarily Homo sapiens) sites in India show that there was little change in activities before and after the eruption, which is preserved by a widespread ash layer in southern Asia.
Farther away, lake cores in East Africa suggest that the environmental impact of the eruption was not catastrophic. Global climate was undoubtedly affected, and the ash deposits in some areas demonstrate that the direct impact was widespread.
Such eruptions will cause major changes to the environment and will require humans to cope with extreme conditions. Our dependency on global trade, electricity, and other aspects of modern life will be impacted and create challenges that our stone-age ancestors did not have to deal with, but we are an adaptable species.
Events larger than Yellowstone's most recent big explosion have already happened while humans have been on the planet. If there weren't enough cataclysms to worry about, a recently published book brought another terrible possibility back into the public spotlight.
Among other calamities, Bryan Walsh's “End Times” highlights the eruption of the Yellowstone super volcano in the United States as an event that could wipe out much of human life on this planet. When it does happen, the eruption would propel something like 240 cubic miles of rock, dust and ash into the sky, like it did during the last major explosion.
Dr. Jerry Zara, a geologist from the University of Silesia in Katowice, Poland, was even more specific, saying in an interview that in his estimate, around 5 billion people would die from hunger “due to the effects of climate change.” Bryan Walsh calls this scenario, without much exaggeration, an “existential risk” not just to the U.S., but the world at large.
Currently, the FAA spends about $7 billion every year on aviation safety while volcano programs, which can potentially cause much more massive casualties, get a paltry $22 million in study expenditures. Yellowstone National Park is a pristine wilderness, full of scenic landscape and iconic hot-pools and geysers that attract tens of thousands of visitors every year.
The ongoing rumbles caused by earthquakes in and around Yellowstone National Park provided the means by which the full extent of the magma chamber was revealed. “The waves travel slower through hot and partially molten material … with this, we can measure what’s beneath.” Dr. Jamie Farrell, from the University of Utah, said.
Super-eruptions on this scale are incredibly chaotic, immediately destroying their surrounding areas with hot flows of molten rock, landslides and ash. The ash spewed by the volcano can fly for hundreds of miles and coat the ground in layers many inches thick.
Simulations run by the US Geological Survey (USGS) show emissions of gas and ash into the atmosphere can have a wider impact on the whole planet. Writing for the weekly USGS Caldera Chronicles, Dr Poland said: “We can be confident of this because there have been two massive explosions while humans were present on Earth, and both of these were actually larger than Yellowstone's most recent cataclysmic eruption.
“The geologic record doesn’t contain any information abut about the New Zealand eruption and its impact on humanity, although climate must certainly have been affected.” According to Dr Poland, the eruption of Toby was considered for many years to have nearly wiped out the fledgling human species.
But the archaeological evidence found from this period suggests early hominids thrived despite the climactic effects of the super-eruption. The historic evidence suggests modern human civilization is prepared to weather the storm of another Yellowstone eruption.
Dr Poland said: “This is not meant to make light of the impacts of future large explosive eruptions. “Our dependency on global trade, electricity, and other aspects of modern life will be impacted and create challenges that our stone-age ancestors did not have to deal with, but we are an adaptable species.
Yellowstone National Park has caught much attention due to its active volcanic eruption, causing catastrophic events in the future. The volcano called Yellowstone Caldera holds power to obliterate the whole U.S. Interestingly, many people believe the government knows about this inevitable eruption, which can happen anytime.
On March 1, 1872, President U.S. Ulysses S. Grant signed the document sanctioning it as the first national park of America. Credits: National GeographicThink of Yellowstone Park as a pressure cooker with the boiling rage to erupt.
The volcano beneath the Yellowstone is a hundred meters deep and can cause violent eruptions with such great power that no one could ever have imagined. Credits: Daily Expressive Yellowstone Caldera Volcano is one of the most dangerous threats that have been weighing heavy on the U.S. government.

Our free booklet, “The Theory of Evolution,” explains that in the past, historic natural catastrophes, including volcanic eruptions, have destroyed large parts of the earth, and the Bible warns that similar events will happen in the near future.
The area is home to literally thousands of different varieties of animals, insects, fish and birds and is one of the main tourist attractions in the US state of Wyoming. Mount Pinatubo in 1981 and the infamous Krakatoa volcano in 1883 caused widespread disruption, death and affected the local climate for some considerable amount of time but with 25 km3 of dense rock thrown out during explosions even they only touched level 6 on the scale.
However, the Montserrat explosion is minuscule in comparison to the potential damage which the Yellowstone National Park super volcano could inflict upon not only America but the worldwide climate. All towns, cities and rural settlements in the local area would literally be wiped out in a split-second as the 500 °C rolling mass of lava and deadly ash destroys everything in its path.
When we talk of natural disasters we often assume that once the pivotal moment has passed, such as the explosion of a super volcano, life and society will get back to normal in the short term. If the Yellowstone National Park super volcano erupted it would literally pump poisonous gases and ash up to 25 km into the air.
The ash is effectively very small particles of razor sharp rock which have been obliterated during the lava flows and explosion and will literally hang in the air for weeks and months. There is evidence of substantial change in the local landscape and the onslaught of a mini ice age over the years, which at one point was thought to have pushed the human race to near extinction.
While literally thousands of the US population would be wiped out in the immediate aftermath of the super volcanic eruption at Yellowstone Park, this figure would be minuscule compared to the damage around the world from both weather change and famine as discussed above. Scientists have been able to examine the fallout from earlier volcanic eruptions and found that this ash is in effect very small particles of razor-sharp rock which can be inhaled and cause severe damage to the lungs.
Vast areas of America would be wiped out by the eruption of the Yellowstone National Park super volcano and the effect on the world would be felt for decades to come. Climate change, imminent deaths and long lingering fatal medical conditions would dominate the earth with many scientists suggesting this is what may well have wiped out the dinosaurs millions of years ago.
