Seven million people buried by lava and molten rock in just two hours.
A colossal eruption on the southernmost main island of Kyushu, which has been struck by seven massive eruptions over the past 120,000 years, would see an area with seven million people buried by lava and molten rock in just two hours, said a Kobe University study released on Wednesday.
Volcanic ash would also be carried by westerly winds toward the main island of Honshu, making almost all of the country “unliveable” as it shut down transportation and other key infrastructure, disrupting the lives of nearly 120 million people, or almost everyone in Japan, they said.
study . The caldera was created 28,000 years ago and has a diameter of 20 kilometers.
A large amount of ash would be carried across the country, .
“We should be aware,” the researchers warn in their report. “It wouldn’t be a surprise if such gigantic eruption were to take place at any moment.”
It would be “hopeless” trying to save about 120 million living in major cities and towns across Honshu, said the study, conducted by Kobe University earth sciences professor Yoshiyuki Tatsumi and associate professor Keiko Suzuki.
Their prediction was based on geological findings from the eruption about 28,000 years ago of the giant Aira Caldera, 23 kilometres (14 miles) across, near what is now the city of Kagoshima on southern Kyushu island.
“It is not an overstatement to say that a colossal volcanic eruption would leave Japan extinct as a country,” the researchers said.
