They looked across to the opposite side of the bay. Someone was waving to them.
"It's Sanjong," Kenner said. "Son of a bitch." He grinned. "I hope he's smart enough to stay where he is. It'll take him a couple of hours to get across the debris. Let's go see if our helicopter is still there or if the wave took it. Then we'll go pick him up."
PACIFIC BASIN
FRIDAY, OCTOBER 15
5:04 P. M.
Eight thousand miles to the east, it was the middle of the night in Golden, Colorado, when the computers of the National Earthquake Information Center registered an atypical seismic disturbance originating from the Pacific basin, just north of the Solomon Islands, and measuring 6.3 Richter. That was a strong quake, but not unusually strong. The peculiar characteristics of the disturbance led the computer to categorize it as an "anomalous event," a fairly common designation for seismic events in that part of the world, where three tectonic plates met in strange overlapping patterns.
The NEIC computers assessed the earthquake as lacking the relatively slow movement associated with tsunamis, and thus did not classify it as a "tsunami-generating event." However, in the South Pacific, this designation was being reexamined, following the devastating New Guinea earthquake of 1998--the single most destructive tsunami of the century--which also did not have the classic slow tsunami profile. Thus, as a precaution, the computers flagged the earthquake to the sensors of the MORN, the Mid-Ocean Relay Network, operating out of Hilo, Hawaii.
Six hours later, mid-ocean buoys detected a nine-inch rise in the ocean level consistent with a tsunami wave train. Because of the great depth of the mid-ocean, tsunamis often raised the sea level only a few inches. On this particular evening, ships in the area felt nothing at all as the big wave front passed beneath them. Nevertheless, the buoys felt it, and triggered an alarm.
It was the middle of the night in Hawaii when the computers pinged and the screens came up. The network manager, Joe Ohiri, had been dozing. He got up, poured himself a cup of coffee and inspected the data. It was clearly a tsunami profile, though one that appeared to be losing force in its ocean passage. Hawaii was of course in its path, but this wave would strike the south shore of the islands, a relative rarity. Ohiri made a quick wave-force calculation, was unimpressed with the results, and so sent a routine notification to civil defense units on all the inhabited islands. It began "This is an information message..." and finished with the usual boilerplate about the alert being based on preliminary information. Ohiri knew that nobody would pay much attention to it. Ohiri also notified the West Coast and Alaska Warning Centers, because the wave train was due to strike the coast in early mid-morning of the following day.
Five hours later, the DART buoys off the coast of California and Alaska detected the passage of a tsunami train, now further weakened. Computers calculated the velocity and wave force and recommended no action. This meant that the message went out to the local stations as a tsunami information bulletin, not an alert:
BASED ON LOCATION AND MAGNITUDE THE EARTHQUAKE WAS NOT SUFFICIENT TO GENERATE A TSUNAMI DAMAGING TO CALIFORNIA-OREGON-WASHINGTON-BRITISH COLUMBIA OR ALASKA. SOME AREAS OREGON-WASHINGTON-BRITISH COLUMBIA OR ALASKA. SOME AREAS MAY EXPERIENCE SMALL SEA LEVEL CHANGES.
Kenner, who was monitoring the messages on his computer, shook his head when he saw this. "Nick Drake is not going to be a happy man today." It was Kenner's hypothesis that they had needed the cavitation generators to extend the effect of the underwater detonations, and to create the relatively long-lasting landslide that would have produced a truly powerful ocean-crossing tsunami. That had been thwarted.
Ninety minutes later, the much-weakened tsunami train struck the beaches of California. It consisted of a set of five waves averaging six feet in height that excited surfers briefly, but passed unnoticed by everyone else.
Belatedly, Kenner was notified that the FBI had been attempting to reach him for the past twelve hours. It turned out that V. Allen Willy had vacated his beach house at twoA. M . local time. This was less than an hour after the events in Resolution Bay had taken place, and more than ten hours prior to the tsunami notification.
