A volcano gushing towering columns of ash closed the airport on the Indonesian tourist island of Bali for a second day, disrupting travel for tens of thousands, as authorities renewed their warnings for villagers to evacuate.

Mount Agung has been hurling clouds of white and dark gray ash about 4,000 meters (13,123 feet) high and lava is welling in the crater.

The local airport authority said closure for another 24 hours was required for safety reasons.

Volcanic ash poses a deadly threat to aircraft, and ash from Agung is moving south-southwest toward the airport.

Ash has reached a height of about 30,000 feet as it drifts across the island.

Volcano continues to spew ash

A long exposure photo taken from Amed in Karangasem captures Mount Agung spewing hot volcanic ash.

Is a larger explosion likely?

Experts said a larger, explosive eruption is possible or Agung could stay at its current level of activity for weeks.

"If it got much worse, it would be really hard to think of. You've got a huge population center, nearly a million people in Denpasar and surroundings, and it's very difficult to envision moving those people further away," said Richard Arculus, a volcano expert at Australian National University.

"There are many examples in history where you have this kind of seismic buildup - steam ejections of a little bit of ash, growing eruptions of ash to a full-scale stratosphere-reaching column of ash, which can presage a major volcanic event," he said.

On Monday, authorities said 100,000 residents living near the volcano had been ordered to get out of an 8-10 km (5-6 mile) exclusion zone.

Tthe population is estimated to be anywhere between 63,000 and 140,000 but just 29,000 people were registered at emergency centres, said Sutopo Purwo Nugroho, a spokesman for the Disaster Mitigation Agency.

"Not all people in the danger zone are prepared to take refuge," he said. "There are still a lot of residents staying in their homes."

The ash spewing out of the volcano is settling on nearby towns and farms.

This picture shows Nyoman, a farmer at Puragae village, checking his chilli plants thas are covered in a thick layer of grey debris.

The possible blast is no trivial matter - Agung's last major eruption in 1963 killed about 1,100 people.

But some of the images taken are spectacular - showing the peak bathed in pink sunlight as it expels the cloud of ash or glowing furiously red against the night's sky.

Tourists and locals have been waiting for updates on the volcano to see if they can travel or return to their homes.

The disaster agency in Bali shared a video ob Facebook of the evacuation and rescue of livestock from the disaster prone areas.

Why can't planes fly through ash clouds?

The ash and particles spouted into the sky can damage plane engines and even cause them to fail completely.

The heat from the engine melts the particles in the air and they are then cooled and solidify again, which can stop the airflow.

This can cause the engine to stall and cut out.

The clouds can also disrupt the sensors on the plane - meaning speed readings can be wrong- and affects visibility for pilots.

If pilots accidentally fly into an ash cloud, the best thing they can do is turn the plane around and seek out an alternative route.

Farmers have been moving their cattle away from the volcano after the area was deemed inhospitable for livestock.

Locals have said the ash is settling on the grass, making it impossible for animals to eat.

Bali volcano live: Latest Mount Agung eruption updates

Indonesian officials have shut the international airport in Bali for a second day, as Mount Agung spews volcanic ash into the atmosphere.

Massive plumes of dark ash were seen reaching as high as 3km (2 miles) above the summit of the rumbling volcano, which began erupting last week.

Officials raised the alert to the highest level on Monday, fearing an imminent major eruption.

Up to 100,000 people have been ordered to evacuate the vicinity.

Volcanic ash can damage aeroplane engines or even cause them to fail, and also clogs fuel and cooling systems. Pilot visibility can also be hampered.

The Transportation Ministry initially closed the Ngurah Rai (Denpasar) airport on Monday morning for 24 hours, cancelling more than 400 flights and stranding 59,000 travellers.

On Tuesday, they announced they would extend the closure to Wednesday 07:00 local time (00:00 GMT).

Sutopo Purwo Nugroho, spokesman for Indonesia's national disaster agency, said that the ash was being drawn southwest - towards Bali's main airport - by a tropical cyclone in the Indian Ocean.

The airport on neighbouring Lombok island however has been re-opened, he added. Authorities have also arranged for buses to take tourists to ferry terminals.

The volcano is about 70km from the popular tourist areas of Kuta and Seminyak.

The disaster agency said in a separate statement (in Indonesian) that as of Tuesday morning, the volcano was still emitting thick ash clouds and that "rays of flares from the glowing lava" were also observed overnight.

Besides ash, streams of rock mixed with water known as lahar have also been spotted flowing down from the mountain. Officials have warned people to stay away from them.

Officials have told everyone living in a 10km exclusion zone around the volcano to evacuate.

Mr Sutopo said that officials faced difficulties estimating the exact number of evacuees given varying population data, but they believe between 90,000 and 100,000 people needed to leave.

So far, only 29,000 people had moved to shelters, while others have fled to other places like Lombok, he said.

Still, there were "many people" who have remained, as some still feel safe while others are unwilling to leave their cattle and fields, he said.

Authorities have warned that they may forcibly evacuate people if they do not move to shelters soon.

Inside the exclusion zone
Rebecca Henschke, BBC News, Bali
A large banner reads: "You're entering active volcanic hazard zone." But looking around, you wouldn't know.

Just behind the sign Seriyani is selling flowers for offers to the Balinese Hindu gods. She says she is worried, but needs to stay here and work to feed the family.

"When it really erupts I will run," she says with a nervous laugh.

Further in the exclusion zone we find a school open. Here the teacher is showing the children how to put on simple surgical masks. To protect them from the ash, the headmaster tells me.

The volcano has been rumbling for weeks now he says so they don't want to move yet and be left in limbo.

Authorities say they will force people to evacuate. But those still on the mountain haven't heard that.

What are the environmental effects of a volcanic eruption

# data[].attributes.body
Volcanoes can impact climate but they also have other environmental impacts.

Use this article as a starting point, then think of at least 3 ways that a  volcanic eruption changes the environment

# data[].attributes.attachment_link.readable_text
When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they cause) reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect.

The cooling influence is particularly marked in the case of large eruptions able to blast sun-blocking particles all the way up to the stratosphere - such as Mount Pinatubo in 1991, which caused a significant dip in global temperatures in the following year or two. It's difficult to know for sure that the cooling observed after a particular eruption is definitely the result of that eruption, but examining the average global temperature change after multiple eruptions proves a strong link.

As for greenhouse gases, underwater and land-based volcanoes are estimated to release, in total, around 100-300 million tonnes of CO2 each year, according to the British Geological Survey and the US Geological Survey. That's a large quantity, but only around 1% of the amount that humans release from burning fossil fuel alone.

As a rule, the cooling influence of an individual volcano will dominate for the period immediately after the eruption but the warming impact will last much longer. So the significance of each depends on the timeframe being considered. A very large volcano in 2011 may significantly reduce temperatures in 2012 but slightly warm them in 2100.

It has sometimes been suggested by those who seek to disprove human impact on the climate that volcanoes release more CO2 than human activity. This is simply incorrect. As the British Geological Survey puts it:

"The contribution to the present day atmospheric CO2 loading from volcanic emissions is ... relatively insignificant."
