Here is the list of all supervolcano locations in the world. Supervolcano is a word that sounds pretty silly. It's not just a regular volcano or even the biggest volcano in the world, it's super. Just super! However, they can only be defined as 'super' if they have shown themselves capable of a VEI 8 eruption. That is most definitely not silly. A VEI 8 has the capability to create extinction level events.
A supervolcano can rain superheated rocks and debris down over great distances. An eruption of that magnitude would fill the atmosphere with ash, sulfuric acid, and sulfur dioxide, and could potentially cause (and actually has, in the ancient past) a new Ice Age. Volcanic eruptions are categorized by the VEI (Volcanic Explosivity Index) on a scale that goes from 0-8, with 0 being non-explosive and 8 being a supervolcanic eruption. In other words, as life-eliminating as you can get. You might think of these kinds of super volcanoes as existing only in prehistoric times, but you would be wrong.
On January 2017, scientists reported that Italy's Campi Flegri, a volcano in the metropolitan area of Naples, showed signs of waking up and approaching critical pressure. Also known as the Phlegraean Fields, the supervolcano region consists of 24 craters. The most recent eruption dates back to 1538, but hundreds of thousands of years ago, Campi Flegrei had a series of massive volcanic eruptions. Although many scientists and researchers doubt an eruption in our lifetimes, it's impossible to say for certain.
If you've ever asked yourself, "Are there any supervolcanoes that threaten life in modern times?" the answer would be six. There are six known, active super volcanoes in the world today.
