A few years back some writers argued that a volcanic eruption on the island of Santorini (about 500 miles north of Egypt), c. 1450 B.C., could have produced a tidal wave that parted the Red Sea. There is no evidence for this view. Others have suggested that a volcanic explosion in the 13th century B.C. parted the Red Sea. Such would hardly have accommodated the Israelites, since the exodus under Moses occurred in the mid-15th century B.C.
