Three volcanoes simmering in Indonesia

Scientists in Indonesia closely monitored three simmering volcanoes across the disaster-prone nation Friday, including the offspring of infamous Krakatau off Sumatra island.

Ash has been spewing some 200 metres (yards) into the air since Tuesday at Anak Krakatau, or Child of Krakatau, the volcano left behind after Krakatau blew in 1883 and killed some 36,000 people, scientist Agus Budianto told AFP.

"We will issue a recommendation for visitors not to come close to Anak Krakatau, (to maintain) at least a three-kilometre (two-mile) distance," said Budianto, Indonesia's Volcanology and Geology Disaster Mitigation Centre.
