It's been a busy day at the Yellowstone National Park. The Yellowstone Caldera will be erupted soon as a matter of fact. Everyone will be leaving the park of course. It is not safe to be at the park. They will try to evacuate from the national park when it erupts. Let's hope that everyone will be leaving the Yellowstone National Park.

"A lot of people are having a great day at the Yellowstone National Park" said the security guard.

"Yes, they have" said the other security guard. "In fact, it is a good weather for us today"

"That is true" said the security guard. "Hopefully that the Yellowstone Caldera won't be erupted"

"Is that the one with the supervolcano?" The other security guard asked.

Later, everyone saw the Yellowstone Caldera started to be erupted.

"Look, sir" said the other security guard. "The Yellowstone Caldera is starting to erupt"

"It is a super eruption" said the security guard.

"That can't be good, sir" said the other security guard.

"It won't be" said the security guard. "We better warn everyone"

"Good idea, sir" said the other security guard.

They warn everyone about the Yellowstone Caldera.

"Everyone, please leave the park immediately" said the security guard.

They saw them leaving the Yellowstone National Park.

"Ladies and gentlemen, due to the Yellowstone Caldera erupted, the Yellowstone National Park is closed until further notice" said the announcer.

"We should go as well" said the other security guard.

"That is true" said the security guard. "It's not safe for us to stay at the park"

They left the Yellowstone National Park and got home.

"We are home now" said the security guard.

"What's happening, honey?" His wife asked.

"The Yellowstone Caldera was erupting" said the security guard. "Thankfully, we just got home safe"

"That's good, honey" said his wife. "I am sure that the supervolcano would end its eruption soon"

"I hope so too" said the security guard. "Yellowstone Caldera is a supervolcano by the way"

The security guards just got home from the national park. See what happens in the next chapter of this long story.
