The 1831 eruption occurred at Zavaritskii volcano on Simushir Island. The explosion generated a 1.87-mile-wide caldera, revealing red, black and white layers made up of past eruptive deposits.

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 researchers conclude that the 1831 Zavaritskii eruption had a magnitude of 5 to 6, similar in power to the 1991 eruption of Mt. Pinatubo in the Philippines, one of the largest volcanic ...

Though the Zavaritskii volcano is remote, its eruption still had a significant global impact on climate with severe consequences for human populations, scientists noted.

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.

As detailed in a new study published in the journal Proceedings of the National Academy of Sciences, scientists say they've determined the culprit to be the Zavaritskii volcano on the extremely ...

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 ...
