The History Channel once aired a documentary claiming a scientific explanation for the Ten Plagues wrought on the Egyptians in Biblical times. In this show, Exodus Decoded, the presenter suggests that a volcanic eruption in southern Europe set forth a chain of events that poisoned and colored the Nile, killing off all river life except for those animals that could leap ashore (frogs); that these frogs could not reenter the Nile, so they died on the land, becoming breeding grounds for vermin, etc.
In Israel too there are volcanos.
Volcanoes appearing in literary contexts may appear with richer description, as in the Biblical:
The One who glances at the earth and it shakes; who touches the mountains and they let out smoke. (Psalms 104)
