Rogue Wave

Chapter 9

As the Japanese students filed out to their van, Kai followed Reggie back into the warning center's telemetry room. Reggie's calm was now replaced by an edginess Kai had only seen a few times.

"Kind of an odd fluke," Reggie said. "Don't you think?"

"What's happening?" said Brad, entering the room. He saw the tension, and his eyes lit up. "Is it a tsunami?"

"Look, Brad," Kai said. "I don't mind if you want to hang around. But we could get very busy. If you're going to get in the way, you'll have to leave."

Brad put up his hands in a gesture of appeasement. "No problem. I just want to watch. This is fun. Usually, your job is so dull." He retreated to the other side of the room and took a seat.

Kai leaned over Reggie as he typed into his computer.

"You think the busted tide gauge is too coincidental?" Kai asked.

"I don't know," Reggie said. "We detect a seismic disturbance in the general vicinity, and that's the exact time for the tide gauge to go on the fritz?"

"It hasn't failed since I've been here, but you said it has in the past?"

"Well, it has broken down two times in the past three years. Once from a short circuit and once from a storm that knocked over the satellite uplink antenna."

"Is there a storm in the area?"

"I just checked. There is one, but the storm is centered 500 miles northwest of Christmas Island. Shouldn't be affecting it."

"How big would the tsunami have to be to take out that tide gauge? Is it a mark seven?"

"Yeah. The wave would have to be at least eight meters high to take out a mark seven gauge."

Over twenty feet high. High enough to cover the entire island.

"Who's our contact on Christmas Island? His name is Steve something, isn't it?" Even after nine months, Kai was still learning who worked with them. He was terrible with names.

"Steve Bryant. He does a little maintenance on the gauge from time to time. No answer, either at his home or his office. In fact, I can't even get his voice mail. It won't ring through. All I get is a fast busy signal."

"Let's try again. The phones down there aren't very reliable. You keep trying to get Steve, and I'll call the operator."

The operator didn't have any better luck getting through, so Kai had her attempt several different numbers they had in the Rolodex for Christmas Island. None of them went through.

"Can you get the main island operator for me?" Kai said.

She tried without success. Just that fast busy signal again.

"All I'm getting is an out-of-order tone, sir," she said.

"Is that unusual?"

"The power goes out down there on a regular basis. It always shuts everything down, including communications. Comms also failed once when there was a fire at the switching station on the island, but we haven't had any problems lately. It's probably just a power outage. Would you like me to continue trying?"

"Yes, please." Kai told her who he was and asked her to call him back when she got through. Their inability to get through to anyone was troubling, and Kai couldn't help feel like there was pattern to all of this that he was missing. Still, he didn't have the hard data to show that it was anything other than a coincidence.

Reggie didn't have any more luck contacting someone than Kai did.

"Any signal from the tide gauge?" Kai asked, hopeful that it was just a temporary glitch.

"Not a blip," Reggie said.

Kai told Reggie the operator's theory about a power outage.

"That's a fine idea," Reggie said, "except for one thing. The tide gauge has a battery backup."

Kai had forgotten about that. Equipment upkeep was not his strength. "It has enough juice for 24 hours, right?"

"Up to 24 hours at full capacity. Of course, that's if the battery is charged. Steve has been known to put off tide gauge maintenance in the past. It's possible the battery is dead. Then a power outage would definitely take the gauge offline."

"So we were expecting a wave to reach Christmas Island at 9:25 AM," Kai said, summing up the series of coincidences. "The tide gauge was supposed to send a signal at 9:30 AM. But there was a power outage on the island that started sometime between when we received the last tide gauge reading at 8:30 AM and we were supposed to receive the 9:30 signal. And because the battery backup was not charged, the power outage knocked out the comm equipment on the tide gauge." Despite the skepticism in his voice, the scenario was possible. Kai would have felt better if the 8:30 signal had also failed to come in, but there it was on the log sheet, right on time.

Reggie opened his mouth to speak, then hesitated.

"What?" Kai said.

"Well, I just thought I should bring it up. Do you want me to send out a warning?"

"A warning?" Brad said. "Oh, this'll be good."

"Brad, please," Kai said, putting up his hand to show that he wasn't in the mood for Brad's giddy enthusiasm. He needed to concentrate.

Sending out a tsunami warning would be a bold step. The situation didn't fit any established scenarios. Kai would simply be going on gut.

Issuing a tsunami warning was not a responsibility that he took lightly, particularly because he had been on the job for less than a year. Doing so would cause a massive disruption to businesses and tourists in Hawaii, not to mention the enormous cost associated with an evacuation.

In 1994 a huge earthquake near the Kurile Islands in Russia measuring a magnitude of 8.1 prompted the PTWC to issue a tsunami warning for the Pacific region. Despite getting some tide measurements at Midway and Wake Islands that indicated a surge could be expected in Hawaii, there was no way to tell whether that wave would be as big as the 1946 tsunami. In fact, a tsunami did arrive, but it never rose above three feet. The tsunami warning had cost the state an estimated $30 million in lost productivity and other associated costs. Because no destructive tsunami occurred, the PTWC got a black eye from the public.

More recently, only two months after Kai arrived at the PTWC, he had issued his first warning based on a magnitude 7.6 quake off the coast of Alaska, but when tide data showed no destructive waves were expected, he called it off 45 minutes later. The financial cost had been minimal, but it didn't help the public trust the system. Many news programs had repeatedly shown videos of frightened residents evacuating the city, even after the warning had been rescinded. The false alarm was implicated as just another failure of federal disaster readiness, even though they had followed procedure to the letter.

A repeat of the full 1994 warning would be even more expensive than it had been then, at least $50 million. And issuing two false alarms in his first year on the job might not kill Kai's career, but it certainly wouldn't help.

"So you think we should issue the warning?" he asked Reggie.

"No, not at all. In fact, I don't think we should. I just wanted to throw it out there. But you're the one who gets the big bucks to make the call."

Kai paused. The signal loss was a strange coincidence, yes, and he couldn't help thinking that there was some small nugget of information that he wasn't seeing that would offer an explanation for what was happening. But the raw data didn't justify a tsunami warning. Historically, the earthquake just wasn't strong enough. Even with a stronger earthquake, a tsunami was unlikely. With the previous tsunami warning Kai had issued, the one that resulted in the false alarm, the earthquake magnitude was over the threshold of 7.5, so he was able to defend his call because he had done everything according to procedure.

But in this situation, for such a small earthquake, they would generally wait until they got a tide reading showing that an actual tsunami was coming before they would issue a warning. If Kai issued a warning based on just his hunch and it turned out to be another false alarm, there would be no defense. Not only would he be criticized by everyone from the governor to the NOAA administrator, but the public would get so frustrated by the repeated false alarms that they might start to ignore subsequent warnings.

"Kai?" Reggie said. "What should we do?"

Kai sighed. Despite his misgivings, he just couldn't issue a warning. Not yet. Not without knowing more.

"We're going to wait," Kai said. "Let's hope the power comes back on soon and we can get on with our day."

Reggie nodded and got back on the phone to keep attempting to reach Christmas Island, while Kai tried to ignore the nagging little voice in his head that said he was making the wrong decision.
