When is Yellowstone volcano going to explode?

The Yellowstone volcano is not just a volcano - it is a supervolcano. Geologists maintain there have been no eruptions for tens of thousands of years. It is constantly releasing pressure, although it appears the ground levels due to the movement of magma have risen several centimetres in the last century. However, despite scientists believing that a major eruption is well overdue, it currently shows no signs of an imminent major eruption.
