May 31, 2014 - INDONESIA - Flights across northern Australia could be affected for days as a vast ash cloud spews from an Indonesian volcano, Australian Deputy Prime Minister Warren Truss says. Sangeang Api, a volcano off the Indonesian island of Sumbawa, has erupted at least three times since Friday afternoon.Flights to and from Darwin International Airport have been cancelled on Saturday as the ash cloud spreads across the Top End and towards Alice Springs.
This is the incredible moment when a huge volcano erupted in Indonesia sending ash spewing an estimated 12 miles into the sky.The powerful explosion took place at Mount Sangeang Api in the Lesser Sunda Islands - an area that plays host to 129 active volcanoes - and sent a distinctive spaceship-shaped ring of pyroclastic smoke high into the air.
The photographs were taken by professional photographer Sofyan Efendi during a commercial flight from Bali to the fishing town of Labuan Bajo in West Nusa Tenggara province.
Scores of farmers who work but do not live on the island were ordered to leave and not return until the volcano has finished erupting, said Muhammad Hendrasto, head of Indonesia's National Volcanology Agency. There are not believed to have been any deaths or injuries as a result of the eruption.
Authorities have had Mount Sangiang Api - which means 'Mountain of Spirits' in Balinese - on high alert for almost a year, he told China's Xinhua news agency. The volcano sits in Indonesia's notorious 'Ring of Fire' - an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. It has 452 volcanoes - 75 per cent of the world's total.Since Sangiang Api's first recorded eruption in 1512, it is believed to have erupted a total of 20 times.
Mr Truss says the ash cloud sits between 6km and 13km in the atmosphere and is sweeping southwest over northern Australia."Depending on wind and other weather conditions, the ash has the potential to affect flights to and from other airports, including Brisbane, during coming days. This is currently being fully assessed," he said.
Air services Australia, the nation's air navigation authority, the Civil Aviation Safety Authority and the Bureau of Meteorology are all investigating the cloud, Mr Truss said."Depending on wind and other weather conditions, the ash has the potential to affect flights to and from other airports, including Brisbane, during coming days. This is currently being fully assessed," he said.
"Passengers are advised to check with their airlines for further information."
Airservices Australia has begun diverting international flights around the ash cloud.

The Civil Aviation Safety Authority says volcanic ash can affect all aircraft with piston or jet engines at all flight levels.
Fine particles of pulverised rock consisting mainly of silica contained in volcanic ash clouds can be highly abrasive and damage aircraft engines, structures and windows.
"Commercial air operators and private pilots planning to fly in this area should conduct a safety risk assessment before any flights," a spokesman said.
"CASA recommends flights are not conducted into areas with visible volcanic ash clouds.
"Flights into areas with low levels of ash contamination should only be conducted after a safety risk assessment has been carried out."
The manager of the Volcanic Ash Advisory Centre at the Bureau of Meteorology in Darwin, Emile Jansons, said the cloud is dispersing as it spreads south but the situation could change at any time.
"It is continuing to disperse but it is moving very rapidly - at 70 to 80 knots (130 to 150km/h) towards Alice Springs," Mr Jansons told AAP.
"There is a very strong jet stream so the boundary (of the cloud) may come further south."
He said no impact is expected on Brisbane but this could change.
Mr Jansons said volcanic ash can be hazardous to aircraft but the decision whether or not to fly is a safety and economic decision that rests with individual airlines.
AEROMEDICAL service CareFlight has scaled its flights from Darwin airport until the volcano dust settles.CareFlight Director Ian Badham said it's being monitored on a minute by minute basis."To mitigate risk, we're responding to really urgent cases," Mr Badham said. "All but urgent emergency flights have been temporarily suspended. We're monitoring it like all other aviation operators. We're looking to life restrictions as soon as it's safe to do so." Careflight has six planes and a helicopter based at its Darwn hanger.
Duty Superintendent Geoff Barnhert said the police plane was still flying because the ash affected only high-level aviation.
The Darwin Volcanic Ash Advisory Centre said most of the Territory is covered by an ash cloud, but it is unlikely to reach Australia's east coast. Flights in and out of Darwin have been cancelled after volcanic ash from Mount Sangeang Api moved across to Australia.
The volcano, which erupted on Friday, is 1373km northwest of Darwin on the Indonesian island of Sumbawa. It is roughly halfway between Bali and Timor.
DVAAC manager Emile Jansons told the NT News it was a "fairly sizeable eruption" but that the cloud over the Territory would be invisible to the naked eye.
"The volcano has been erupting to 15km in the air," he said. "It has moved across the Kimberley and western Top End. It's high in the atmosphere so there won't be any ashfall different to normal bushfire ashfall."
He said there should be negligible impact on the air quality compared to usual Top End dry season weather, and said adverse health effects were unlikely.
There is no official announcement yet, but word on the ground at Darwin Airport is most flights will be cancelled until Monday.
Asked to look into his crystal ball to get an end date, Mr Jansons said: "It continues to erupt - it's still going up right now - but how long it'll go I don't know. They tend to stop after a day or two so it's unlikely to reach the east coast. It's almost reached Tennant Creek in the south. It won't get to Brisbane or Sydney."
He said his office monitors cloud images and distributes information to aviators to make decisions. The ash can harm aircraft engines and structures, depending on the concentration of ash in the air. "It's a hazard in the atmosphere," he said. It's a situation for airlines to balance the safety costs or the damage costs."
Darwin International Airport's website shows all incoming and outgoing flights have been cancelled.
