Discover the incredible story of the Zavaritskii Caldera, the "lost" volcano that changed the climate. In 1831, a massive volcanic eruption dimmed sunlight, caused weather disruptions, and even triggered famines. For years, scientists were baffled by the mysterious sulfur spike in ice cores—until now. Learn how researchers traced this colossal eruption to the remote Kuril Islands, uncovering one of nature's hidden disasters. Could the next big eruption be hiding in plain sight? Find out in this fascinating exploration of Earth's volatile power.

00:00Imagine a massive volcanic eruption, so powerful it dimmed sunlight,
00:04caused blue hazes, and disrupted weather worldwide.
00:08Yet, no one knew where it happened until now.
00:11Scientists have long been puzzled by a mysterious sulfur spike in ice cores from 1831.
00:17It hinted at a colossal eruption, but the source was missing,
00:21until researchers uncovered the secret.
00:24Meet the Zaviritsky Caldera,
00:26a remote volcano in the Kuril Islands between Japan and Russia.
00:29With fewer than 120 people living within 100 kilometers today,
00:34it's easy to see how an eruption here in the 1800s went unnoticed,
00:38but the impact was anything but small.
00:41Using cutting-edge geochemical analyses,
00:44researchers matched sulfur isotopes from ice cores to ash from Zaviritsky.
00:48The verdict?
00:50This invisible eruption rivaled the 1991 Pinatubo eruption in scale,
00:55triggering global climate effects and even famines in Japan and India.
00:59Volcanic eruptions like this remind us of nature's hidden power.
01:03Many past disasters have come from volcanoes we thought were quiet.
01:07What other surprises could be lurking?
01:10Mapping and studying volcanoes like Zaviritsky is more critical than ever.
01:14After all, the next big eruption could be hiding in plain sight.
