Along with Zavaritskii, three other volcanoes blew their tops between 1808 and 1835. They marked the waning of the Little Ice Age, a climate anomaly that lasted from the early 1400s to around 1850.

Now, a new study from scientists at the University of St. Andrews in the U.K. says they’ve solved the mystery: Zavaritskii volcano in the Kuril islands northwest of Japan is to blame.

Zavaritskii volcano in the Kuril Islands was responsible for the mysterious 1831 volcanic eruption that cooled the climate and turned the sun different colors, a new study finds.

The eruption at Zavaritskii volcano created a nearly two-mile-wide caldera with layers of red, black and white from previous eruptive deposits. Oleg Dirksen In the summer of 1831, an enormous ...

The team used evidence from well-dated ice cores and other geological records to pinpoint the Zavaritskii caldera— an "extremely remote" volcano situated on the uninhabited island of Simushir in ...

The team discovered it was the Zavaritskii volcano on the remote, uninhabited island of Simushir, which is part of the Kuril Islands – a disputed territory between Russia and Japan.
