Diana, Sue and Nancy are having a great time at Yellowstone National Park. They are going to talk about the supervolcano as a matter of fact. They have been studied about the supervolcano of course. The girls are spending the night in Wyoming. They are going back to Yellowstone to see that supervolcano. Let's hope that Diana and her friends will look at the supervolcano.
"We are back now, girls" said Diana. "Back at Yellowstone"
"It is nice to come back to Yellowstone" said Sue. "Where did we spend the night at?"
"We stayed at Cody, Wyoming, Sue" said Diana. "In fact, it's nice to visit to Yellowstone"
"Why don't we go look around" said Nancy.
"Let's go, girls" said Diana.
They went to look at the geyser for a bit.
"Look, water is coming out" said Sue.
"I can see that, Sue" said Diana. "Look at the lava"
"It is a supervolcano, Di" said Sue. "We could see smoke coming out"
"Same here" said Diana. "We would get killed if the supervolcano was erupted"
"I hope that won't happen, Di" said Sue.
"Me either, Sue" said Diana. "We better not like it happen"
"I agree with you, Di" said Nancy. "We have seen a supervolcano once"
"What is a supervolcano, Di?" Sue asked.
"A supervolcano is a large volcano that had an eruption of magnitude 8, which is the largest value on the Volcanic Explosivity Index" said Diana. "The means the volume of deposits for that eruption is greater than 1,000 cubic kilometers"
"I know Yellowstone is one" said Sue. "Let's go ahead and look at the Yellowstone Caldera"
They went there and looks at it.
"That is a nice place to see the Caldera" said Diana. "We can see the Yellowstone River"
"It is flowing through Hayden Valley" said Nancy. "Nice river to see"
"I could visit to Yellowstone again" said Sue. "It is a good place"
"We could a take a picture of them" said Diana.
She took a picture of Yellowstone National Park as well as the supervolcano. See what happens in the next chapter of this long story.
