"Unprecedented Survey Reveals Largest Volcano Eruption in 11,700 Years"

A recent survey of volcanic deposits off the coast of Japan has revealed that a volcanic eruption 7,300 years ago formed a large underwater caldera, making it the largest volcanic eruption in the past 11,700 years. The Kobe University research team used seismic imaging and sediment sampling to study the event, estimating the erupted volume to be between 133 and 183 cubic kilometers. The findings provide valuable insights into the dynamics of volcanic mega events and their impact on global climate and human history.

"Record-Breaking Ancient Volcanic Eruption Near Japan"

Scientists have confirmed the largest volcanic eruption in the Holocene, occurring around 7,300 years ago at the Kikai Caldera near Japan's Kyūshū island. By analyzing sediment samples and using seismic imaging, researchers estimated that the Kikai-Akahoya eruption covered an area of 4,500 square kilometers, making it the largest volcanic eruption of the Holocene. Understanding past super eruptions is crucial for predicting and preparing for future volcanic events, as they have significant global and historical impacts.
