People say that long long ago there was a big elephant under the earth.
When that elephant shakes his ears, an earthquake comes up, is the story our ancestors told.
What was said was that whenever the elephant shakes his ears, the earth shakes.
Therefore they call an earthquake a hwa:ti (sounds like hadi), they say.
When he shakes one side of his ears, the earth shakes.
And he continues to put up the earth on his shoulder.
After he gets tired, he shifts.
When he tries to put up (the earth) on the other shoulder, at that time the earth turns over (collapses), it was said, and if the earth turned over, then all things, the earth stopped being.
Then later there was another earth, is the story I have heard, but it's only a story.
