Which is the most dangerous volcano in the world?

Scattered throughout our planet are gigantic volcanos with fiery peaks and molten rock. Dispersed along our coasts, islands, and inland areas, these volcanos are a natural vent to the planet’s crust. Transferring scorching hot lava from the depth of the Earth’s core to the surface through explosive eruptions. Volcanos have been around long before humans arrived, existing for thousands of years. Nowadays, there are an assortment of volcanos still remaining, ranging from frequently active, dormant, or even extinct that are merely mountains now. Here is our list of the deadliest volcanos to humans on earth.

Mount Vesuvius

Mount Vesuvius is famously known as the volcano that destroyed Pompeii. Leaving behind a buried city that was burned alive in 79 A.D. A good deal of people may believe that a volcano’s devastation is due to the hot lava that flows from its top, but it is much more complex than that. With waves of different events that aid in a city’s destruction. For the Pompeii people, their tragic end was meet by the large pyroclastic waves of gas, ash, and debris that hurtled down towards the city at speeds of 700km per hour. Hitting the people that burnt them alive with temperatures up to 700 degrees Celsius. Mount Vesuvius is said to be due for another eruption, which could cause catastrophic damage for around 3 million locals and tourists surrounding the volcano. The magma lying underneath the volcano in wait is said to be one of the largest volumes of magma on record.

Mount Rainier

What makes this volcano on the top deadliest is its high elevation, chemical composition, and its distance from residences. A neighbour to Washington’s Seattle and Tacoma suburbs, the area is covered in tall pines and pure white snow. However, once Rainier erupts, the heat would melt the snow on top the mountain, causing a devastating wave of mud and debris, named lahar, to sweep to the nearby towns. If this happened, it would affect around two million people, with only 10 to 15 minutes to escape.

Novarupta Volcano

The volcano has gone down in history with the most powerful eruption of the 20th century. It is located in the Katmai National Park within Alaska. Although the surrounding area to Novarupta in inhabited, past eruptions have seen its ash cloud reach across southern Alaska and parts of Canada.


Michoacan-Guanajuato is quite unique, instead of a large mountain, it is in fact a large volcanic field that takes the form of a large cinder cone. Its impending danger for the nearby Mexico’s citizens makes it one of the riskiest volcanos around. With over 6 million people dwelling within 5 kilometres of this volcanic field, a current eruption could cause catastrophic harm.
