One is looking at the Volcanic explosivity index, which is [basically] how big of a bang the eruption made. The last supervolcano eruption took place 26,000 years ago at Lake Taupo in New Zealand. No volcano has come close. The power varies widley. Some burst to life in explosive eruptions, like the 1991 eruption of Mount Pinatubo, and others burp rivers of lava in what's known as an effusive eruption… But each volcano is different. The A.V. Some eruptions simply ooze small amounts of lava, while other eruptions can consist of a series of massive explosions that last for days. Ash, mudflows, and lava flows can devastate communities near volcanoes and cause havoc in areas far downwind, downstream, and downslope. Mt. The Pinatubo eruption is considered to be the most powerful volcanic eruption of the 20 th century. Novarupta Volcano Erupts! The total amount of energy released in Mt St Helens eruption was 24 megatons , 7 of which were a direct result of the blast. Located in Skamania County, Washington, the volcano is widely known for its deadly eruption in 1980, which is the deadliest and most economically destructive volcanic eruption in the history of the United States.

Novarupta spewed 13 cubic kilometers (3.1 cubic miles) of magma, which turned into 30 cubic kilometers (7.2 cu mi) of ash that blanketed the nearby area.

There are a couple of ways of looking at this question.

The usual figure supplied is that is was equal to a 24 megaton nuclear explosion. it ejected more than 100 cubic kilometers of tephra.

Supervolcano 100,000 Years Ago Cut Human Population to Just 11,000 According to scientists, the human population hit a “genetic bottleneck” about 100,000 years ago.

People in Juneau, Alaska, about 750 miles from the volcano, heard the sound of the blast – over one hour after it occurred. The Earth’s atmosphere rises about 300 miles, in six layers.

Pinatubo was VEI 6 and is usually rated around 70 megatons, or larger than any nuclear blast to date. That is a very very large nuclear blast, but the Tsar Bomba was larger at 50 megatons.
