ALBAWABA - A beach in Iran's Hormuz Island recently turned red, and footage of the haunting visuals went viral on social media, capturing the rare incident. 

This came amid heavy rainfall across Iran on Dec. 10, after the country experienced one of its driest autumns in 50 years, which led to issues including drought. Videos of the incident flooded social media, sparking debate among users regarding the rare "blood red" color. 

Why did the beach turn 'blood red' in Iran's Hormuz Island?

While many wore their tinfoil hats, linking the incident to an early sign of the apocalypse by referencing the Book of Revelation, scientific evidence states that the vivid red color comes from the high amounts of iron oxide in the island's soil and rocks. 

According to Wion, the beach turned crimson red when rain came into contact with Hormuz's iron oxide-rich soil and rocks.

A social media user wrote on X (formerly Twitter), "It looks biblical. Is this common?" 

Another wrote, "Yes, Hormuz Island is indeed majestic (w/ red, silver & black coasts) But doesn't red rivers & Iran's current plight remind anyone of Exodus 7:17?"

They added, "...I will smite with the rod that is in mine hand upon the waters which are in the river, and they shall be turned to blood."
