Harry Turtledove - Supervolcano :Eruption

She’d never been on a private jet. Having enough room to stretch out in her seat made her want to abandon Southwest, American, and United forever. “I could get used to this,” she said as the plane taxied toward takeoff.

“In that case, what are you doing studying geology?” asked her chairman, who had the window seat beside hers. Geoff Rheinburg was gray-haired and pudgy, but more than plenty sharp. “You should have gone into programming and turned into an Internet billionaire. Then you’d have a jet for every day of the week-two for Saturday, if you wanted.”

“I spend more time doing geology than flying,” Kelly answered after a little thought. “And I can use computers, but I’m not much for making them sit up and beg. This is more fun.”

“Then you may possibly be in the right place after all,” Rheinburg allowed. Was he old enough to have started out on a slide rule, back in the days before pocket calculators? If he wasn’t, he came close.

The plane shot down the runway and zoomed into the sky. Air traffic here and most places in the USA was still screwed up, with flights way, way off their usual level. Maybe that tough black gal had checked out the bagels for no better reason than that she was bored stiff.

“This is the pilot speaking.” The Learjet’s intercom had better sound quality than a commercial airliner’s. The man’s voice didn’t sound as if it were coming through a tin-can telephone. He went on, “I am going to give you the usual advice-keep your seat belts fastened at all times. I mean it more than usual, though. We will be flying over the crater at forty thousand feet. Look for turbulence all the same. That sucker is enormous, and it is hot. Hot air rises-why do you think old politicians float away and never get seen again?”

That won him a few startled laughs. Kelly wondered if he’d ever flown for Southwest. She hated the seating stampede, but enjoyed the way the crew sometimes spoofed the usual instructions about seat belts and exit rows and oxygen masks.

“My brother-in-law told me I needed my head examined when he found out I was making this flight,” the pilot went on. “I told him I needed some help with the down payment on a house I want to buy… That doesn’t necessarily make him wrong, you understand. What’s your excuse, folks?”

“He ought to be doing stand-up,” Kelly said.

“We can’t throw things at him when he’s behind that locked door,” Professor Rheinburg said. “Too bad, isn’t it?”

They flew on. The engines… sounded like engines. Kelly approved. There was still a lot of dust and ash in the air, and the supervolcano’s afterbelches-major eruptions on any normal scale, but the scales weren’t normal now, and wouldn’t be for a long time-kept adding more. The planes that were flying needed much more frequent engine overhauls than anyone had dreamt they would.

From Oakland to Yellowstone was about an hour and a half. No, not to Yellowstone: to the supervolcano crater. Yellowstone was gone, dead, off the map in the most literal meaning of the words. Yellowstone had either fallen half a mile toward the center of the earth or was buried deep in lava or pyroclastic flows or volcanic ash. Yellowstone was screwed, blued, and tattooed, not to put too fine a point on it.

People worked on laptops or fiddled with the sensors and other instruments that were the real reason for the flight. The pilot didn’t make the usual announcement about electronic devices. The geologists might have lynched him if he had. Without electronic devices, they fell all the way back to the start of the twentieth century, or maybe even to the nineteenth.

After a while, the pilot did come on to say, “Folks, we are getting close. I’m going to do what I’m supposed to do when turbulence is likely. I’m going to tell you to make sure you’re in your seats with your belts securely fastened. Don’t be dumb, now. If there isn’t turbulence flying over this critter, then there’s no such animal. We don’t want to have to scrape you off the ceiling-or off your neighbor’s lap.”

Geoff Rheinburg gave Kelly a wry grin as he checked his belt. “No offense, but the only gal I want on my lap is my wife,” he said.

“Okay by me,” she answered, tightening her own a little. She knew he was happily married. Nice that somebody was. She figured Colin would get up the nerve to propose one of these days before too long. She also figured she would get up the nerve to say yes when he did. What happened after that was a crapshoot-as far as she could see, just like every other marriage since the beginning of time.

“Three minutes till we reach the edge of the crater,” the pilot said. “Welcome to the biggest goddamn roller coaster in the world.”

Kelly peered out. Unlike a commercial airliner’s, the Learjet’s windows were big enough to give even somebody in an aisle seat a good view of the wider world. She’d looked down into active volcanoes before. She’d gone to the Big Island of Hawaii: yeah, work as a geologist could be rough. But the volcanoes there, which went off pretty much all the time, were as different as you could get from the Yellowstone supervolcano. The supervolcano was like the little girl saving up more spit. It saved and it saved and it saved till its igneous cheeks couldn’t hold any more. Then-

Then it went and trashed half the continent. And that was only the first act. The follow-up, which did a number on the whole planet, was just getting started.

Even in the wide-windowed Learjet, she leaned toward happly married Professor Rheinburg to see better. He didn’t wince, so she hadn’t forgotten her deodorant even though she’d crawled out of bed at some heathen hour. Lots of gray and brown down below. Nothing green, not any more. Life would be trying to reboot down there. It had likely already succeeded in a few tiny spots, but not in a way you could see from eight miles high.

Or eight and a half… The edge of the world fell away, down below. As soon as it did, the plane started bouncing in the air. Yes, the crater was heating things up, wasn’t it? Oh, just a little.

Here and there, the floor had already crusted over and looked like, well, bare rock. One of these days, one of these centuries, it would form the bottom of the new caldera that would take the place of the one at the heart of Yellowstone. They’d need to give it a new name. Kelly wondered whether they’d still speak English when they got around to it.

Lava still boiled and bubbled in between the congealed places. It wasn’t as impressive as the stuff in The Return of the King. For one thing, that lava was CG. For another, you were looking at it up close and personal, not from forty-odd-thousand feet. Kelly, who’d first read The Lord of the Rings when she was nine, wondered what would happen if you dropped Sauron’s dread creation right into the middle of this. She expected it’d be gone for good. Hell, if Mount Doom happened to sit on top of a supervolcano hot spot, one of these days it would have been gone for good. That was why there was a big stretch of the Rocky Mountains without any mountains.

“Some of those patches of molten rock are miles wide,” Rheinburg murmured, most likely to himself.

Even if he wasn’t talking to her, it was a useful reminder. The scale of this thing was… ridiculous was one of the words that occurred to her. Then the Learjet did some up-and-downs she devoutly hoped it was designed for. As urgently, she hoped the bagels of mass destruction would stay put.

“For anyone who needs the reminder, you have airsick bags in the pockets of the seats in front of you,” the pilot said. “If you need them, I do hope you’ll use them. We don’t want the next batch of passengers to think we were playing Vomit Comet, now do we?”
