Social Media Claims of Colombia Blood Rain Debunked
Fact-checkers identified viral videos as mislabeled footage from Iran and India.
Updated on Sept. 19, 2026 in Natural Disasters
Viral social media posts claiming that blood rain occurred in La Sierra Choco, Colombia, were proven false after verification. The footage actually originated from separate natural phenomena in Hormuz Island, Iran, and Kerala, India.
Why it matters
Disinformation often misattributes natural phenomena to unrelated locations to trigger alarm. Identifying the source of such misleading content prevents the spread of baseless fears regarding local environmental safety.
Laboratory testing of the 2001 Kerala, India, event confirmed red particles contained no DNA or blood cells. Similarly, the red soil on Hormuz Island is composed of volcanic soil with high concentrations of iron oxide.
The players
Facebook is a global social media platform where the false claims regarding the Colombia weather event first began circulating in August 2026.
Instagram is a photo and video sharing platform that hosted the original 2025 footage of the red soil cliffs on Hormuz Island.
The details
Verification teams used reverse image searches to trace the clips, revealing that footage of red-soil cliffs originated from Hormuz Island, Iran, while the red rainfall footage dated back to a 2001 event in Kerala, India. The Indian phenomenon, previously analyzed via EDAX and DNA testing, was confirmed to be free of biological material.
Timeline
July 2001: Red rain event occurred in Kerala, India.
October 22, 2025: Footage from Hormuz Island was posted to Instagram.
August 18, 2026: False claims began circulating on Facebook.
Seasonal Patterns
This incident follows a pattern established by the 2001 Kerala red rain event, where natural meteorological or geological anomalies are frequently misinterpreted or weaponized online. By confirming these events are purely natural, scientists continue to refine the public record regarding such geological phenomena.
Readers should exercise caution when viewing sensationalist meteorological content on social media by utilizing reverse image search tools. Verifying the geographic and temporal origins of viral clips helps maintain a factual understanding of global events.
The takeaway
Misinformation often gains traction by stripping context from real, explainable natural events to create a false sense of urgency. Developing a habit of checking the original source of viral videos is the most effective way to identify and stop the spread of digital misinformation.
