Volcano ash-hit Bali airport reopens, flights resume

Thousands of foreign tourists were expected to leave Bali by plane on Thursday, following a nearly three-day airport shutdown sparked by a rumbling volcano on the Indonesian holiday island.

The alert level on Mount Agung remains at the maximum, but a change in wind direction blew towering columns of ash and smoke away from the airport, prompting authorities to re-open the island’s main international gateway on Wednesday afternoon.

The move raised hopes for some of the 120,000 tourists stranded after the surge in volcanic activity grounded hundreds of flights since Monday, sparking travel chaos and forcing the evacuation of villagers living in its shadow.

Ash is dangerous for planes as it makes runways slippery and can be sucked into their engines.

“Since the airport reopened (Wednesday), some flights have resumed operation and things are gradually getting back to normal,” said airport spokesman Israwadi, who like many Indonesians goes by one name.

More than 4,500 people have now flown out of the airport, authorities said.

On Wednesday evening, domestic carrier Garuda said it would start flights to several cities across the vast archipelago nation, while AirAsia flew to the Malaysian capital Kuala Lumpur.

However, the airport on nearby Lombok Island – also a popular tourist destination – closed again on Thursday after ash and smoke drifted in its direction.

Millions of tourists visit the palm-fringed island hotspot annually. The majority are Chinese, followed by Australians, Indians, Britons, and Japanese, according to the immigration office, which added that nearly 25,000 foreigners live on the small Hindu-dominated island.

Tens of thousands of Balinese have already fled their homes around the volcano – which last erupted in 1963, killing around 1,600 people – but as many as 100,000 will likely be forced to leave in case of a full eruption, disaster agency officials have said.

High alert

Experts said Mount Agung’s recent activity matches the build-up to the earlier disaster, which ejected enough debris – about a billion tons – to lower global average temperatures by around 0.3 degrees Celsius for roughly a year.

While the volcano appeared to be belching less ash and smoke on Thursday, experts urged caution and have warned a major eruption could happen at any moment. It has already experienced a series of mini eruptions.

“The potential for an eruption is still there, but we cannot predict how big the eruption is going to be,” said Devy Kamil, a senior volcanologist from the Indonesian volcanology agency.

“The volcano is still on the highest alert level,” the expert noted.

Mount 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 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.

So-called cold lava flows have also appeared, similar to mud flows and often a prelude to the blazing orange lava of popular imagination.

Indonesia, the world’s most active volcanic region, lies on the Pacific “Ring of Fire” where tectonic plates collide, causing frequent volcanic and seismic activities.

In 2016, seven people were killed after Mount Sinabung on the western island of Sumatra erupted. A 2014 eruption at Sinabung killed 16 people.      /kga
