In the summer of 1831, an enormous volcanic eruption spewed sulfur gas into Earth’s atmosphere. The particles scattered sunlight, making our star appear green, purple and blue. Its rays struggled to reach the planet’s surface,

The location of a giant volcanic eruption in 1831 has eluded scientists for nearly 200 years, but now they have solved the mystery.

Scientists have identified the “mystery volcano” that erupted in 1831 and cooled Earth’s climate. They have linked it to an island volcano in the northwest Pacific Ocean.

In 1831, the Earth shuddered. A massive volcano erupted with such ferocity that it dimmed the skies and cooled the planet. Crops failed, famine spread, and the Northern Hemisphere entered a climate-altered reality.

While scientists have known that the major climate event reported during this period was caused by volcanic activity, the exact identity and location of the volcano remained a mystery – until now. A new study published in the journal PNAS found the Zavaritskii volcano on the remote,
