Experts say a massive volcanic eruption could cause immediate destruction, change the global climate and leave millions of people homeless. Is humanity prepared to face this threat?
What would it be like to wake up one day and discover that the world is facing a volcanic eruption that could change the course of history? This is a real concern for scientists. A massive volcanic eruption, like the one at Mount Tambora in 1815, would not only devastate entire cities but also cause lasting global impacts. The warning is clear: it’s a question of “when,” not “if.”
Over the centuries, volcanoes have shaped the Earth, creating stunning landscapes and sometimes, scenarios of destruction. But what if we are on the eve of a catastrophic event? Understand why this threat is so serious.
Why is volcanic eruption so destructive?
In 1815, the eruption of Mount Tambora in Indonesia was a landmark event in history. This super-eruption released tons of ash and gases into the atmosphere, reducing global temperatures by 1 degree Celsius. The result? A “year without a summer,” with destroyed crops, widespread famine and cultural impacts, including the creation of the classic “Frankenstein.”

Events of this magnitude are not common, but they are not rare either. Scientists say that supereruptions can occur every 600 years. What makes them so feared is the scope of their effects: from climate change to the destabilization of entire economies.
How could a massive eruption impact the modern world?
Imagine entire cities being buried by ash, lava waves and pyroclastic flows. The interruption of production chains could cause trillions of dollars in economic losses in a matter of months.
Volcanic ash not only darkens the sky, it also cools the planet. This means failed harvests in major agricultural powers like the U.S. and China, leading to famine and global instability.
Why would the impact be more severe today?
The planet is now hotter and more unstable. Aerosols released by volcanoes could be dispersed more quickly, intensifying global cooling. Warmer oceans could worsen climate impacts.
With more than 800 million people living near active volcanoes, the number of people displaced would be staggering. Global interconnectedness also means that the economic and social impact would be felt by everyone, regardless of distance.
Potential volcanoes
Scientists have not pinpointed a specific volcano that is about to erupt, but they are closely monitoring supervolcanoes known for their destructive potential. Volcanoes that could cause a massive eruption include:
Yellowstone (USA) – Located in Yellowstone National Park, it is one of the most monitored supervolcanoes in the world. Its last major eruption occurred about 640 years ago.
Phlegraean Fields (Italy) – Near Naples, this supervolcano has shown signs of increasing activity in recent years. Its eruption could affect millions of people in Europe.
Toba (Indonesia) – Responsible for the largest eruption in the last 100 years, Toba is believed to have almost wiped out prehistoric humanity.
Taupo (New Zealand) – It had its last supereruption 26.500 years ago and remains one of the most dangerous active volcanoes on the planet.
Aira Caldera (Japan) – A constantly active volcano, with the potential for a supereruption that would affect much of Asia.
These volcanoes have the characteristics necessary to generate an eruption capable of causing local destruction and global climate impacts. The scientific warning is based on data that indicates that we are within the expected time range for an event of this magnitude, although it is not known for sure which volcano will be responsible.
How can we prepare for the inevitable?
Today, we have enough technology to monitor signs of volcanic activity. Sensors and satellites can provide early warnings, but are we ready to act quickly?
Preparedness includes evacuation plans, strategic food stockpiles, and international coordination. After all, in an interconnected world, the response needs to be global.
The power of a massive volcanic eruption reminds us that, despite all our technology, we are still small in the face of the power of nature. History has given us clear signs, but have we learned from them?
Human activities; with nuclear tests underground or at sea; among other things; can cause seismic activity which could accelerate volcanic activity; an earthquake; a tsunami and other natural activities; but not natural.
The forces of nature can be provoked; but they would be difficult to control…
Humanity’s self-destruction events…
