Summary
Ice cores from Greenland and Antarctica show a 1452/1453 eruption blasted about 11 megatons of sulfur into the stratosphere, enough to cool climate worldwide even though the volcano remains unidentified.
No diagnostic ash has been found to trace the source, but historical and natural records point to broad fallout: tree rings in Europe and North America show frost damage and stunted growth.
Chinese chronicles describe the human toll in 1453 and 1454, with several feet of snow in six provinces, tens of thousands freezing to death, and 40 days of snow south of the Yangtze.
The eruption also may explain reports during Constantinople's fall in May 1453, when a red glow over Hagia Sophia was likely sunlight reflecting off high volcanic ash clouds.
Could a mysterious volcanic eruption have sealed the fate of the Byzantine Empire in 1453?
How can modern science find a lost volcano that triggered a global winter nearly 600 years ago?
The 1452/1453 Volcanic Winter: Tracing the Source and Impact of a Forgotten Global Catastrophe
Overview
The 1452/1453 volcanic eruption stands as a major geological mystery that continues to puzzle scientists even in 2026. Although overwhelming evidence from ice cores, tree rings, and historical records confirms a powerful global climatic event, the exact volcano responsible remains unidentified. This enigma highlights the challenges of reconstructing past events, especially with scarce or ambiguous historical accounts. As a result, multidisciplinary scientific investigations are ongoing, using advanced techniques to analyze geological and environmental clues. The search for the eruption’s source underscores both the complexity of Earth’s processes and the persistent efforts of modern science.
