Scientists say one of Japan’s most active volcanoes is due for a major eruption within the next 30 years, who have studied a build-up of magma there.
The Sakurajima volcano on Japan’s Kyushu island poses a “growing threat”, researchers at the University of Bristol say.
The volcano, located 49 km (30 miles) from the Sendai nuclear plant, is also close to Kagoshima, a city of 600,000.
Sakurajima’s last deadly eruption was in 1914, when 58 people died.
The Japanese archipelago, which sits on the Pacific “Ring of fire”, has more than 100 volcanoes. Sakurajima regularly spews ash and there are many small explosions there each year, with the latest eruption being in February.
