Hydrothermal explosion rocks Yellowstone causing onlookers to run in panic

Yellowstone National Park sits atop the largest super volcano on the continent, and while it is considered to be a dormant volcano it still causes geological events across the park, such as hydrothermal geysers.

Yellowstone is home to more than half of the world's geysers and contains the tallest active geyser, the Steamboat Geyser, which erupts every 90 minutes. Geyser explosions are commonplace in Yellowstone, but not every day is there a significant explosion caught on video. The large explosion took place in the Biscuit Basin, and reports indicate it was a hydrothermal explosion and (luckily) wasn't a catalyst to awaken the dormant super volcano.

A hydrothermal explosion is a rapid ejection of boiling water, steam, mud, and rock fragments. The event occurs when pockets of fluids rapidly transition to steam, and since vapor particles are much larger than water particles, extreme pressure is placed on the surrounding rocks. Pressure reaching a proverbial "boiling point" and boom. Mud, boiling water, and steam are all launched outwards. The above video shot by visitors at the park shows them running in fear as the explosion is taking place.

No injuries were reported after the event, and the super volcano beneath Yellowstone hasn't exhibited increased activity.
