When Krakatoa Exploded in 1883, It Turned Skies Blood Red Around the World and Convinced New Yorkers Their City Was on Fire

On August 27th in 1883, the island of Krakatoa in Indonesia tore itself apart in one of the most violent volcanic eruptions ever recorded, and what followed was so strange that people around the world genuinely believed something otherworldly was happening to the sky itself. The eruption produced what many scientists still consider the loudest sound in recorded history. The sonic boom was heard clearly nearly three thousand miles away in places like Australia and the island of Rodrigues near Mauritius. Barometers across the globe registered the pressure wave as it circled the entire planet multiple times, something instruments had never captured before or since with such clarity. But the truly unexplained part, at least to the people living through it, came in the weeks and months afterward. Massive amounts of volcanic ash and sulfur dioxide were blasted so high into the atmosphere that they created a phenomenon now called the Bishop's Ring, a hazy corona of light around the sun that puzzled observers everywhere. Sunsets turned brilliant shades of green, purple, and blood red across Europe, the Americas, and beyond, colors so vivid and unnatural that they inspired panic in several cities. In New York City, the sky glowed such an intense red one evening that fire departments received a flood of emergency calls from citizens convinced that Manhattan itself was ablaze. Firemen rushed out with equipment only to find no fire at all, just an eerie crimson sky stretching endlessly overhead with no visible source. Similar reports came in from Poughkeepsie, New Haven, and towns across the northeastern United States, all completely unaware that the cause was volcanic debris drifting from a mountain on the other side of the world. Some art historians have even speculated that Edvard Munch's famous painting The Scream, with its swirling blood orange sky, may have been inspired by these very sunsets, which persisted for nearly three years after the eruption due to aerosols lingering in the stratosphere. Munch himself wrote about walking along a road at sunset when the sky suddenly turned to blood, describing a sensation of nature letting out an infinite scream. Whether or not that moment was directly tied to Krakatoa's ash cloud remains debated, but the timeline lines up unnervingly well. Global temperatures actually dropped in the following year as the ash layer reflected sunlight back into space, contributing to unusually cool and strange weather patterns that farmers and scientists struggled to explain at the time, since the concept of a volcano on one side of the earth affecting climate on the other side was not yet widely understood. There were also countless anecdotal reports of unusual animal behavior in the days leading up to the eruption, with sailors near the Sunda Strait describing eerie silences on the water and strange luminous clouds forming in patterns some described as unnatural or deliberate, though these accounts remain firmly in the realm of folklore rather than verified science. So on this date, if you happen to catch an oddly vivid sunset painted in shades that seem almost too intense to be real, you might just be witnessing an echo of that same atmospheric mystery that gripped the world back in 1883, when a mountain exploded with such force that it turned sunsets into something people genuinely feared, and left scientists puzzling for years over how one eruption could rewrite the color of skies on the opposite side of the globe.
