What does Jiya do when he sees the devastation of the big wave?

As the earth yields to the internal fire, a big wave rises higher and higher. Jiya yearns to warn his father, but Kino's father will not let him leave because it is too late. The wave encompasses the village, reaching the terrace wall where they stand before receding to sea. The village is gone as if no humans ever lived there. Jiya lets out a cry and slips to the ground unconscious because, "What he knew, he could not bear. His family and his home was gone" (page 22).
