Great Wave off Kanagawa by Katsushika Hokusai.
A Japanese boy lives with his grandfather. On a very hot day, a low rumble comes and makes the house shake.
After an earthquake, an old man and a boy look out over the bay – watching the sea mysteriously retreat.
The village people find all sorts of marvellous things uncovered on the beach.
But the old man lights a fire on the hill and all the villagers think he has gone crazy.
