A recent bout of earthquakes has sparked fears the supervolcano under Yellowstone could erupt. A NASA scientist has revealed the space agency's risky plan to prevent the Yellowstone super volcano erupting. Brian Wilcox has shared a report on the natural hazard that was previously unseen outside the space agency.

He also revealed that the methods the agency is considering to prevent one could also cause the volcano to go off by accident. One of the "risky" plans includes drilling to the bottom of the the volcano and using high pressure water to release heat from the magma chamber.

"I came to the conclusion during that study that the supervolcano threat is substantially greater than the asteroid or
