Aira Caldera, Supervolcano in Kagoshima Prefecture, Japan
The Aira Caldera extends 23 kilometers in length and 17 kilometers in width, forming a substantial depression in the southern region of Kyushu Island.
The formation of Aira Caldera occurred 22,000 years ago through an immense volcanic eruption that dispersed tephra and ignimbrite across the surrounding territories.
The residents of Kagoshima have developed specific protective measures, including mandatory hard helmets for students to guard against volcanic debris.
The Sakurajima Volcano Research Centre maintains continuous monitoring systems to assess volcanic activity and provide safety information to local communities.
The caldera contains an underground magmatic chamber connected to the Kirishima system, which supplies magma to Sakurajima volcano, causing gradual expansion.
