Yellowstone is known as a site that sits on top of a dormant volcano, which experts believe to be a supervolcano that is waiting to erupt. Located northwest of the state of Wyoming in the western United States, the Yellowstone National Park is also home to many geysers and hot springs than any other place on Earth, according to national park officials. US seismic authorities estimate that Yellowstone's most recent volcanic activity was approximately 70,000 years ago.

Since its discovery more than a century ago, the Yellowstone supervolcano has been a subject of both 'fictional and scientific inquiry' regarding a future post-apocalyptic world should the said dormant volcano erupt. However, this scenario inclines more on the side of reality since there is strong evidence that the Yellowstone volcano can reportedly cause immediate fatalities in its surrounding areas, as well as global ramifications.

Available data shows that the 70,000-year-old most recent volcanic activity from the Yellowstone supervolcano consisted of rhyolitic lava flows, according to the USGS. Meanwhile, Yellowstone's last official volcanic eruption occurred approximately 640,000 years ago.

Beyond the said timeline, scientists also estimate that the Yellowstone volcano erupted 1.3 million and 2.1 million years ago. This means that there is no one alive today who witnessed Yellowstone and other supervolcanoes in the world erupt. The previous eruptions at Yellowstone also do not clearly indicate that its dormant supervolcano erupts every 600,000 years.

Described by many as the "sleeping giant," scientists predict that the most likely activities that will occur at Yellowstone include volcanic earthquakes, lava flows, or hydrothermal explosions, with a major volcanic eruption to be unlikely, according to the YVO.
