Rainfall this week briefly transformed the coastline of Iran's Hormuz Island, as runoff washed iron-rich soil into the sea, turning the water shades of deep red. The island's Red Beach is known for its vivid sand and cliffs, created by high concentrations of iron oxide. When rain falls, streams of red soil flow towards the shore, creating a striking contrast with the blue waters of the Persian Gulf. The rare phenomenon regularly draws tourists, photographers and social media attention to the island.
