The reason for earthquakes

365. From him, from Salih, from one of his companions, from Abdul Samad Bin Basheer, who has reported the following: Abu Abdullah (asws) has said that: ‘The whale which is carrying the earth secretly said to itself that it is carrying the earth by its own strength. So Allah (azwj) the High Sent to it a fish smaller than a palm’s length, and larger than a finger. So it entered in its gills and shocked it. It remained like that for forty days. Then Allah (azwj) Raised it and was Merciful to it, and Took it out. So whenever Allah (azwj) Intends the earth to be in a quake, He (azwj) Sends that (small) fish to that (big) fish. So when it sees it, it becomes restless, so the earth gets engulfed by the earthquake’.
