Unexpected surprise

The Yellowstone National Park attracts millions of visitors each year but recently tourists were surprised by some unexpected excitement during their visit.

A sudden explosion

On July 23 a sudden hydrothermal explosion scared visitors in the Biscuit Basin, a popular Yellowstone National Park area (pictured).

Scared visitors

One of the witnesses, Vlada March, caught the event on camera. The exposition happened as visitors strolled through a boardwalk.

"It became dark"

Ms. March told the newspaper that the giant ash cloud covered the sun, turning everything dark. She added that her 70-year-old mother was covered in ashes after getting caught in the explosion.

Areal View

The National Park Service later shared this areal view of the explosion in social media. The light gray area, they explained, shows how far fragments of rock and mud were tossed.

Hot steam

Michael Poland, the scientist in charge at the Yellowstone Volcano Observatory, told the NY Times that these explosions happen when water becomes steam in the park's underground water system.

Closed temporarily

After the explosion, the NPS clarified on social media that no injuries were reported, and the extent of damage is still unknown. Still, they closed the area to the public.

Assesment

The NPS also said, "Park staff and staff from USGS (United States Geological Survey) will monitor conditions and reopen the area once deemed safe."

Other basins

According to The NY Times, similar explosions occurred earlier this year in the Norris Geyser Basin, another Yellowstone area.

A very active park

According to the NPS, over half of the world's active geysers are in Yellowstone National Park. Their website says around 500 to 700 geysers are active yearly.
