Alert level up
Karangasem, Indonesia – A rumbling volcano on the resort island of Bali could erupt at any moment, authorities warned Monday as they raised alert levels to maximum, accelerated a mass evacuation and closed the main airport, leaving tourists stranded.
Massive columns of thick grey smoke that have been belching from Mount Agung since last week have now begun shooting more than three kilometers into the sky, forcing flights to be grounded.
Some 40,000 frightened people have fled their homes around the volcano but as many as 100,000 will likely be forced to leave, disaster agency officials said after raising the alert to its highest level.
The exclusion zone around Agung, which is 75 kilometers from the beachside tourist hub of Kuta, has also been widened to 10 kilometres.
“Continuous ash puffs are sometimes accompanied by explosive eruptions and a weak booming sound,” the National Board for Disaster Management said.
“The rays of fire are increasingly observed at night. This indicates the potential for a larger eruption is imminent.”
Agung rumbled back to life in September, forcing the evacuation of 140,000 people living nearby. Its activity decreased in late October and many returned to their homes.
However, on Saturday the mountain sent smoke up into the air for the second time in a week in what volcanologists call a phreatic eruption – caused by the heating and expansion of groundwater.
On Monday so-called cold lava flows appeared – similar to mud flows and often a prelude to the blazing orange lava seen in many volcanic eruptions.
“I’m very concerned because I left my house behind and I’m also worried about my family,” said 36-year-old farmer Putu Suyasa, who fled with some of his relatives from a village eight kilometres away from the volcano.
“The mountain is spewing thicker smoke than before.”
Mt. Agung last erupted in 1963, killing about 1600 people in one of the deadliest eruptions in a country with nearly 130 active volcanoes.
The airport in Bali’s capital Denpasar, a top holiday destination that attracts millions of foreign tourists every year, has been closed, a move expected to affect tens of thousands of passengers.
“I have to make sure that the runway has no ash,” said Bali airport’s general manager Yanus Suorayogi.
While there was dismay from some tourists who were unable to return to their homes and jobs, others took events in their stride.
“What can I say? We have to cooperate because this is a natural disaster,” said Indian visitor Krisna Mustafa.
Many were told that even in the best scenario it would take several days before they could leave.
