What volcano could destroy the world?
The Yellowstone supervolcano
is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it. This Yellowstone Volcano has been dated to be as old as 2,100,000 years old, and throughout that lifetime has erupted on average every 600,000-700,000 years.

has long been designated the world's largest volcano, rising more than 30,000 feet (9,170 meters) above the seafloor of the Pacific Ocean and encompassing more than 19,200 cubic-miles (80,000 cubic-kilometers) in volume.
Can a volcano erupt without warning?
In this case, magma is shallow, and the heat and gases affect surface and ground water to form vigorous hydrothermal systems. … The resulting steam-driven eruption, also called a hydrothermal or
phreatic
eruption, can happen suddenly and with little to no warning.
