A newly openedvolcanic vent has been discovered in Yellowstone National Park, emitting thick plumes of steam and prompting scientists to investigate a potential link to the supervolcano’s complex hydrothermal system.

It may be famous for its reliable 'Old Faithful' geyser, but one should never forget that Yellowstone National Park sits on top of a rumbling, dynamic, active supervolcano.

Today, Yellowstone remains a place of low volcanic risk. Sure, there are sometimes small explosions stoked by hot water and steam. But it's mostly thermal pools and awesome geysers, reminding us of what could potentially awake, one distant day.
