Videos from Hormuz Island in Iran have gone viral after heavy rains turned the coastal waters of the Persian Gulf a striking blood red, evoking biblical imagery and sparking apocalyptic fears. The phenomenon, reminiscent of scenes from the Book of Exodus and Revelation, was attributed to iron-oxide-rich soil on the island, which washes into the sea during storms and tints the water crimson. Hormuz Island, known as 'Rainbow Island' for its colorful mineral deposits, regularly experiences this effect when rain interacts with its unique geology. Similar events have occurred elsewhere in the region, including the Sea of Galilee in Israel, where a recent red transformation was caused by harmless algae blooms.
