How a single supervolcano eruption could trigger a global volcanic winter
In short: This video explores the catastrophic scale of VEI-8 eruptions. It explains how specific geological giants could release enough ash and gas to collapse civilizations and potentially initiate a new ice age.
The Volcanic Explosivity Index (VEI) categorizes eruptions from quiet lava flows like Mauna Loa to mega blasts. While smaller events are localized, VEI-7 and VEI-8 eruptions—such as the devastating Toba event that nearly wiped out humanity—can unleash ash clouds and toxic gases on a global scale.
The video examines high-risk sites including Yellowstone in the USA and Campi Flegrei in Italy. These supervolcanoes possess the potential to cause mass famine and disrupt climate systems by creating a 'volcanic winter,' where massive pyroclastic flows and atmospheric debris block out sunlight.
