FYI... there's a live Volcano underneath.

I think a lot of people outside of America said, "It's finally started."

[reichjef]

I’d be so concerned about steam burns and latent gas. Afterwards folk are just milling around.

[groaningmole]

Wow, an explosion above a volcanic hot spot, who'd've thunk it.

[Barot]

The woman who keeps yelling run saved people from immediate injury.

[carolynbrubaker]

Yikes. I've lived most of my 70 years within a hundred fifty miles of the park. Never seen anything like this!

[johnnynbk]

"hey, you wanted to see the geyser right??"

[coleengoodell]

How terrifying! It's miraculous that there were not serious injuries or deaths. Thank God!

[djk]

There's an active supervolcano under there!

[bestill]

Random and without warning?! You gotta be kidding me 😂

[HilltopZombieShop]

"let's go to a supervolcano for a vacation."

[ryen]

Lots of people need to be reminded it's not Disneyland. First the bison, now this 😂

[maskedduelist]

Geyser: starts geysering*

Tourists: Surprised Pikachu face*

"Hydrothermal explosions are common in Yellowstone" Apparently the park service never got the memo when they built the walkway right next to the pool🤷🏽‍♂.

[Primo_extracts]

Wow, they were so fortunate to not be injured, give thanks🙏

[markwred]

I have a great Idea lets charge a fee to let people get close to volcanos

[Walter_Sobchak_]

Look how those falling rocks destroyed that wooden fence and bench. Imagine what they wouldve done to a skull. 😮

[ericscott]

People are freaking out way too much about this, this has been happening with geysers there for tens of thousands of years since it erupted 70, 000 years ago.

[kimbarleemoon]

How long have those walkways been there and never got destroyed before by a geyser, some people are acting like this is normal!

[Catlover-luwy]

Mother Nature reminding us all that she is still in charge.
