Mysterious blood-red sky appears after Colombia earthquake
A mysterious red sky over Colombia has attracted widespread attention. Videos showing deep crimson clouds began circulating on social media. Local residents filmed the unusual scene near Galeras days after a powerful earthquake struck western parts of the country.
The timing led some people to connect the so-called “blood sky” with seismic activity. Images of the intense red clouds quickly spread online. Some users speculated that the strange color was linked to the recent earthquake.
The deep red and crimson colors are most likely caused by an atmospheric optical effect. Sunlight passes through moist air, clouds, dust, and other particles. Shorter blue wavelengths are scattered more strongly. Longer red and orange wavelengths can then dominate the light seen by an observer.
Dense cloud layers can make this effect even more dramatic. The position of the Sun also plays an important role. Under the right conditions, an ordinary sunset can temporarily produce an intense blood-red sky.
There is no established scientific evidence linking the red clouds directly to tectonic activity. The earthquake itself did not necessarily cause the unusual colors. Their appearance shortly after the disaster was most likely a coincidence.
The magnitude 7.4 Colombia earthquake occurred on August 10, 2026. Its epicenter was reported in the Chocó region of western Colombia. It was described as the strongest earthquake to affect the country in around a decade. The disaster caused widespread destruction.
The earthquake and the later appearance of the unusual red sky created a striking sequence of events. The footage may look ominous. However, atmospheric science offers a natural explanation for the extraordinary colors.
It was previously reported that scientists around the world had been unable to explain the mysterious blood waterfalls in Antarctica for over a century. Now, a group of researchers has presented the clearest explanation to date.
