At one time, volcanic eruptions were thought to be a punishment from the Gods.
Nowadays, we know volcanic eruptions are a result of glowing hot magma being forced up from the mantle through vents in the earth’s crust. Of course, that doesn’t make their explosive effects any less devastating.
Here is a list of volcanoes most likely to erupt and wreak tragedy on surrounding communities and the environment at large:
1. Yellowstone Caldera, United States of America
The bubbling sulfuric hot springs and erupting geysers of Yellowstone national park have long attracted tourists from far and wide. The park is breathtakingly beautiful and awe inspiring. But underneath the beauty of Yellowstone lies a super-volcano that has the potential to wipe out the Western United States and alter the course of human history.
As the name suggests, super volcanoes are volcanic eruptions that are, well, big. Really big. In fact, super volcanoes are a phenomenon that has never been observed by mankind. The last supervolcano explosion we know of occurred 640,000 years ago in Yellowstone. The first known super volcano explosion 2.1 million years ago was an incredible 25,000 times larger than the 1980 eruption of Mt. St. Helens which killed 57 people and hurled volcanic ash around the world.
Unlike traditional volcanoes, super volcanoes don’t have a cone shaped mountain, instead they form what are known as calderas – the sunken areas that are left over from previous super volcano eruptions. Essentially, all of Yellowstone is a giant caldera, ready to blow and devastate humanity. Experts estimate that a Yellowstone eruption would kill 87,000 people immediately, while the clouds of ash and gas would enter the jet stream and have untold effects on the world’s food supply.
2. Mt. Vesuvius, Italy
Mount Vesuvius in Campagnia, Italy has a history of activity that makes it one of the world’s most dangerous volcanoes. It last erupted in 1944, but it usually has an eruption cycle of just 20 years. Moreover, 3 million people live relatively close to the crater, as it sits just 5 miles east of Naples. This makes it the most densely populated volcanic region in the entire world.
Mt. Vesuvius is the only volcano to have erupted on the European mainland within the last hundred years, and is probably most famous for its massive eruption in 79 AD, when it buried the cities of Herculaneum and Pompeii.
3. Popocatépetl, Mexico
Popocatépetl is a large, glacier covered peak that lies around 35 miles from Mexico City. Around 9 million people live within Popocatépetl’s blast radius, and it has erupted more than 20 times since 1519.
It last erupted in 2000. Thank fully, preventative evacuations of 41,000 people from surrounding towns prevented a major catastrophe.

4. Sakurajima, Japan
This composite volcano in Japan was once its own island, but lava flows in its 1914 eruption caused it to connect to the mainland. Many experts refer to it as the “Vesuvius of the east”, due to its high level of volcanic activity.
Every year, thousands of small explosions come from Sakurajima’s peak, throwing up ash over the surrounding areas. However, a major eruption could have deadly consequences for the 700,000 residents of Kagoshima, who live just miles from the Volcano. The city even has special volcano shelters where people can go to take cover from falling debris.
5. Galeras, Columbia
Located in Southern Columbia near the border with Ecuador, Galeras has been active for at least 1 million years. It erupts frequently, with its first recorded eruption dating back to 1580. More alarming is the fact that a city of 450,000 residents – the city of Pasto – lies on its eastern slope.
While it went dormant in 1978, it went active again in 1988 after just 10 years. When scientists held a Decade Volcano conference in 1993 to address the dangers of Galeras, an unexpected eruption occurred, killing 6 scientists and 3 tourists. Since 2000, it has erupted almost every year, spouting out ash and lava and causing tremors in the region.
