Supervolcano could kill 100 million people
A supervolcano beneath Japan is beginning to wake from a 7000-year slumber and researchers say it could kill some 100 million people.
Located 50km south of Japan's most southern main island Kyushu, the volcano named Kikai is showing signiifcant signs of activity with the seabed being forced upwards 610 metres by more than 31 cubic kilometres of lava.
There is ample evidence according to Japanese volcanologists that Kikai erupted some 7000 years ago, releasing 500 cubic kilometres of magma. Other evidence also suggests super-eruptions occured 95,000 years ago and 140,000 years ago.
There is about a 1 per cent chance of a "catastrophic" eruption in the next 100 years according to volcanologist Yoshiyuku Tatsumi.
