World's Largest and Deadliest Volcanic Eruptions in History

There are hundreds of volcanoes in the world. Some are active and some are dormant. Most active volcanoes are located in a region called “Pacific Ring of Fire”.

There are hundreds of volcanoes in the world. Some are active and some are dormant. Most active volcanoes are located in a region called “Pacific Ring of Fire”. Volcanic eruptions are naturally occurring phenomena which can either be beneficial or devastating to human beings. Beneficial because they cool down the Earth and make the land fertile. Destructive because they claim lives and destroy properties.

Mount Mazama’s eruption is estimated to have been as much as 42 times more powerful than Mount St. Helens eruption in 1980. If this volcano will erupt once more with the same power, it will surely be a very devastating one.
