Watch the world's top ten biggest volcanic eruptions

New Delhi: Our earth is full of Nature's wonders. From dense forests to deserts, from oceans to the mountains, nature has splendid mysteries for us. One of such mysteries is the volcanic eruption. It is said that a volcano erupts due to excessive heat within the earth's mantle. This heat slowly melts rocks to create magma. Magma is lighter than the solid rock around it. Magma rises and collects in magma chambers. It is a natural way by which the internal heat and pressure of the planet is released. Although there are numerous volcanoes around the world, but many of them are either extinct or are in a dormant state. There are around 1500 volcanoes across the world.Volcanic eruptions have a great impact on life and property.Here we present a list of 10 biggest volcanic eruptions:Mount Unzen Located in Nagasaki, Mount Unzen is a group of several overlapping stratovolcanoes.

Mount Vesuvius A stratovolcano in the Gulf of Naples, Mount Vesuvius is termed as one of the most dangerous volcanoes in the world. It is popular for its eruptions in AD 79 when its eruption vented a cloud of stones and ash upto the height of 33km. This eruption released a hundred thousand times the thermal energy quite equivalent to the energy released at the time time of Hiroshima bombing. Approximately 16,000 people were killed in this eruption.Nevado Del Ruiz Nevado Del Ruiz is a volcano located at the border of the Caldas and Tolima in Colombia and is held responsible for Armero tragedy.

The lava, during the explosion, were estimated to reach a height of 1400 meters with 120 million tonnes of toxic sulfur dioxide. Lake Toba Known as a supervolcano, Lake Toba is located in the middle of the northern part of the Indonesian island of Sumatra. Lake Toba's massive supervolcanic eruption estimated to have occurred around 69,000 to 77,000 years ago, is considered as the largest known explosive eruption on Earth in the last 25 million years. The eruption of Toba led to a volcanic winter with a worldwide decrease in temperature between 3 to 5 °C , and up to 15 °C in higher latitudes.
