Dragon - Cussler Clive. Страница 114

Because water is incompressible, it forms an almost perfect medium for transmitting shock waves. Traveling at almost two kilometers a second, the shock front caught and overtook Big Ben as the vehicle forged across the trench slope only eight kilometers distant, a good four kilometers short due to the vehicle’s agonizingly slow passage through the mud. The pressure wave pounded the huge DSMV like a sledgehammer against a steel drum, but it took the blow with the unyielding toughness of an offensive lineman for the Los Angeles Rams blocking a tackler.

Even then, as the energy shock and raging wall of swirling silt washed over the DSMV, shuttering all visibility, Pitt felt only jubilation. Any fear of failure was swept aside with the explosion. Relying blindly on the sonar probes, he drove through the maelstrom of sediment on a juggernauting course into the unknown. He was running on a long ledge that ran midway down the long slope, but his progress was only a few kilometers faster than it had been on the steeper grades. Adhesion between the tractor belts and the mud was only marginally improved. Any attempt to drive the great mechanical monster in a straight line became impossible. It skidded all over the slope like a truck on an icy road.

Pitt fully realized his life hung by an unraveling thread, and that he was in a losing race to escape the path of the coming landslide. The chance of his being overtaken was a bet no self-respecting bookmaker would turn down. All fear was detached, there was only his stubborn determination to survive.

On the surface, unseen in the darkness, the plume of spray rose to 200 meters and fell back. But deep in the fault zone below the bottom of the trench, the shock waves forced a vertical slippage of the earth’s crust. Shock followed shock as the crustal fracture rose and fell and widened, creating a high-magnitude earthquake.

The many layers of sediment laid down for millions of years shifted back and forth, pulling the heavy lava of Soseki Island downward as though it was a rock in quicksand. Cushioned by the soft, yielding sediment, the great mass of the island seemed to be immune to the initial shock waves during the first minutes of the quake. But then it began to sink into the sea, the water rising up the palisade walls.

Soseki Island continued to fall until the underlying layers of silt compressed, and the floating rock mass slowed its descent and gradually settled on a new level. Now the waves no longer crashed against the base of the cliffs, but broke over the jagged edges and lapped into the trees beyond.

Seconds after the explosion and the ensuing seismic blows, an enormous section of the eastern trench wall shuddered and bulged menacingly. Then with a great thundering roar, hundreds of millions of tons of mud slid away and plunged to the bottom of the trench. An incredible pressure wave of energy was generated that rushed toward the surface, forming a mountainous wall of water below the surface.

The indestructible tsunami was born.

Only a meter in height on the open surface of the sea, it quickly accelerated to a speed of 500 kilometers an hour and rolled westward. Irresistible, terrifying in its destructive power—there is no more destructive force on earth. And only twenty kilometers away, the sinking Soseki Island stood directly in its path.

The stage was set for disaster.

The death of the Dragon Center was imminent.

Tsuboi, Yoshishu, and their people were still in the defense control room tracking the southerly course of the crippled C-5 Galaxy.

“Two missile strikes, and it’s still flying,” Yoshishu said in wonder.

“It may crash yet—” Tsuboi suddenly broke off as he sensed rather than heard the distant rumble as Mother’s Breath exploded. “Do you hear that?” he asked.

“Yes, very faintly, like the faraway sound of thunder,” said Koyama without turning from the radar display. “Probably from a lightning storm echoing down the ventilators.”

“You feel it too?”

“I feel a slight vibration,” replied Yoshishu.

Kurojima shrugged indifferently. The Japanese are no strangers to earth movement. Every year more than a thousand seismic quakes are recorded on the main islands, and a week never passes when Japan’s citizens do not notice the ground tremble. “An earth tremor. We sit near a seismic fault. We get them all the time. Nothing to worry about. The island is solid rock, and the Dragon Center was engineered to be earthquake resistant.”

The loose objects in the room rattled faintly as the bomb’s dying energy passed through the center. Then the shock wave from the shift in the suboceanic fault slammed into the island like a gigantic battering ram. The entire Dragon Center seemed to shake and sway in all directions. Everyone’s face registered surprise, then the surprise gave way to anxiety, then the anxiety to fear.

“This is a bad one,” Tsuboi said nervously.

“We’ve never felt one this intense,” Kurojima uttered in shock as he pushed his back and outstretched arms against a wall for support.

Yoshishu was standing quite still as if angered by what was happening. “You must get me out of here,” he demanded.

“We are safer here than in the tunnel,” Koyama shouted above the growing tumult.

Those who were not holding on to something were thrown to the floor as the shock wave tore beneath the lava rock, undulating the deep sediment below. The control center was jolted more savagely now as the island shifted back and forth during its descent into the mud. Equipment that wasn’t bolted down began to topple over.

Tsuboi pushed himself into a corner and stared numbly at Kurojima. “It feels like we’re falling.”

“The island must be settling,” Kurojima cried in fright.

What the horrified men in the Dragon Center did not know, could not have known, was that the titanic bulk of the tsunami was only two minutes behind the shock waves.

With Pitt on manual drive, Big Ben slugged tortuously through the mud, sliding ever closer toward the floor of the trench. The tractor belts constantly lost their hold, sending the DSMV sideways down the grade until their leading edges piled up the silt, dug in, and regained their grip.

Pitt felt like a blind man driving the tractor in a blind world, with only a few dials and gauges and a screen with little colored words to guide him. He weighed his chances, sizing up the outside situation as it was revealed by the sonar-laser scanner, and came to the conclusion that so long as he was still mired in sediment his only escape was by a miracle. According to the calculations by the geophysicists, he had not traveled nearly far enough to escape the predicted reaches of the landslide.

Everything depended on finding firm ground or rock structure that was stable and would resist tearing away from the wall of the trench. Even then, his toughest hurdle was the trench itself. He was on the wrong side. To reach the safety of the Japanese shore, he would have to drive the great vehicle down into the bottom and up the opposite slope.

He did not see, his scanner could not tell him, that there was no hard ground or shallow slopes for the DSMV to claw its way up to flat terrain. If anything, the great fracture in the seabed deepened and curved southeast, offering no chance of escape for over eight hundred kilometers. And too late, his scanner revealed the mighty seismic landslide flaring out across the eastern bank of the trench, much as sand spreads when falling through an hourglass, and closing on him at an incredible rate of speed.

Big Ben was still battling through the soft ooze when the avalanche caught up to it. Pitt felt the ground slipping away under the vehicle and knew he’d lost the race. The sound of it came like the roar of a cataract in a tiled room. He saw death’s finger reaching out to touch him. He just had time to tense his body before a great wall of mud engulfed the DSMV and swept it end over end into the black void far below, concealing it under a burial shroud of featureless ooze.
