  • A lattice-work ladder leading to a platform. Instruments and cables are placed on the lattice and platform. Caption: to study an earthquake at ground zero.

    Understanding what happens at the epicenter of an earthquake, as the tectonic plates beneath the earth shift and the earth shakes, could help better predict when and where the next big one will hit. For the past six years scientists from a number of institutions have joined in a project called San Andreas Fault Observatory at Depth, or SAFOD. They have drilled to the core of the San Andreas Fault, near Parkfield California, down to a specific area along the fault known to experience a number of small earthquakes every year. By retrieving and studying core rock samples from that site, geologists Chris Marone and Brett Carpenter and hydrogeologist Demian Saffer are getting a better understanding of the types of rocks involved in major quakes, versus the rocks present at more forgiving ones.

He decided to row as far as he could toward the horizon to catch the sun or reach the end of the earth! But night fell and Moko, in the middle of the ocean, began to get scared. Moko closed his eyes in fear and waited. After a while, he opened his eyes and looked around him. He had landed on a cape and felt hope that he finally knew what lay beyond the ocean.

In this episode, the snow's thaw is drawing to a close and the mountain is shedding its white robe. Alarick and Moko are fishing in one of the mountain's springs and are catching nothing. They ask an old wise man to tell them where there might be fish. He points them towards the road to the "Ancient Mountain." They follow the road the old man told them about and reach a green luxuriant hill covered with fruit trees and streams. They think that this hill--smaller than their mountain, richer and greener--younger and simply hasn't grown up yet. Moko and Alarick explore the natural process of erosion.

To prevent the volcano from erupting, Moko offers it a beautiful seashell, as Mei-Lei's ancestors did. The mountain's rumbling stops and Moko is proud to have learned its language.

Just beyond the village Moko sees a vast plain that has been flooded with water. He thinks this must have been the great wave, flooding the field with water so that the rice would grow. This is when Mei-Lei picks up a magnificent seashell and Moko believes that it must surely be a gift from the ocean. Moko and Mei-Lei make their way back home, carrying their gift and happy to have seen wonderful new places. They are certain that the ocean must know an underground passage in which it sends waves every now and then to feed the rivers and the fields.
