The article features the Yellowstone supervolcano located in Wyoming underneath the Yellowstone National Park. Topics mentioned include the record of seismometers on the number of earthquakes in a year indicating that the volcano is active, the caldera which is created by the ancient eruptions, and the illustration that the crust of the North American tectonic plate are moveable.

The article reports that Derek Schutt and Ken Dueker estimated the temperature of the plume of the supervolcano beneath Yellowstone National Park in Wyoming with the use of seismic waves. The supervolcano exploded 642,000 years ago, covering half of what is now the U.S. in ash. The source of its eruption is not certain, yet suspicion focuses on a large plume of hot mantle. The temperature of the plume is around 1450 degree Celsius which suggests an end to the sequence of mega-eruptions.

The article offers information on the supervolcano called the Yellowstone Caldera in Yellowstone National Park in Wyoming. It states that a supervolcano is larger than a normal volcano and forms when magma rises from the Earth's mantle, creating a reservoir in the Earth's crust. The impacts if Yellowstone erupts are described. According to the article, it is important to monitor Yellowstone's activity so that inhabitants can be forewarned and prepared.
