Did you know a mystery volcanic eruption in 1831 caused global temperatures to plummet, triggering devastating famines and crop failures worldwide? For nearly 200 years, scientists couldn’t pinpoint the culprit—until now. Researchers from the University of St Andrews have identified the source: Zavaritskii Volcano on Simushir Island, part of the disputed Kuril chain. Using tiny ash shards preserved in ice cores, they unlocked the secrets of this catastrophic event.
This discovery is a chilling reminder of nature’s power and the hidden dangers of dormant volcanoes. Are we prepared for the next big eruption? Learn more about this groundbreaking research and the lessons it holds for the future.

00:00Did you know a single volcanic eruption almost wiped out the world 200 years ago?
00:05Scientists have finally cracked the mystery
00:07behind Earth's most recent mystery eruption from 1831.
00:11In the spring of 1831,
00:13a massive volcanic explosion caused global temperatures to plummet by 1°C.
00:19This led to devastating famines and crop failures across the planet.
00:23But the question remained.
00:25Which volcano was responsible?
00:28After years of research,
00:29a team from the University of St. Andrews,
00:32led by Dr. Will Hutcheson,
00:34matched microscopic ash shards found in ice cores to a remote volcano,
00:38Zavoritsky on Simishir Island in the Kuril Chain,
00:42a region disputed between Russia and Japan.
00:45These ash shards are tinier than a human hair,
00:48but their chemical fingerprint told the story.
00:50It was a eureka moment in the lab
00:52when the volcanic ash matched perfectly with the ice core data.
00:56Today, Simishir Island is controlled by Russia
01:00and used as a military outpost.
01:02But this discovery reminds us of nature's power
01:05and the importance of preparing for future eruptions.
01:08Scientists warn that many hidden volcanoes still pose a threat.
01:12Will we be ready when the next big one hits?
