Indonesia volcano Mount Sinabung erupts with clouds of ash

A volcanic eruption in Indonesia has sent colossal clouds of ash shooting five kilometres into the sky, and forced airlines to issue a 'red notice' as thousands of locals flee from searing gas.

Mount Sinabung on the island of Sumatra spewed huge plums of smoke after it erupted on Wednesday afternoon. Locals could only watch on as the smoke engulfed the sky. 

Airlines have been issued a 'red notice', barring them from flying over parts of Indonesia because of the eruption.

A red notice is issued when ash is in the atmosphere, and aircraft are not permitted to be in the airspace.

A Jetstar spokesman told Daily Mail Australia the eruption has not affected any of their flights. A Qantas spokeswoman said none of their flights had been affected either.

National disaster management agency spokesman Sutopo Nugroho said a plume of thick ash was sent five kilometres into the sky.

He said there were no casualties as a result of the eruption.

 Incredible video footage showed the North Sumatra volcano erupting which caused dangerous ash rain to fall. 

Indonesian officials said there are no casualties yet but residents nearby should watch out for lava.

 The mountain which usually stands against a picturesque scene, has been at its highest alert level after its first eruption four years ago. 

The suffocating ash travelled three miles from the volcano causing thousands to flee to avoid the dangerous ash rain

The Indonesian National Disaster Mitigation Agency have warned against locals getting near the danger zone which is within three to seven-kilometres around Mount Sinabung's crater.  

Authorities feared lava flows could cascade down the mountain and destroy homes, as has happened several times.

The volcano explodes so frequently, warning signs are permanently stationed around it warning against going near it.

Earlier this year, another eruption rocked the area, blasting ash 4.2km into the air and causing pyroclastic flows many kilometres across surrounding countryside.

Ten people were killed in another eruption this year, with its death toll sitting at 20 in the past decade, including four high school students and their teacher on a school excursion. 

Sinabung is located on the 'Ring of Fire', a volatile zone of seismic activity with hundreds of active volcanoes and 90 per cent of the world's earthquakes.
