Bali volcano: Mount Agung sparked fears after sending a thick black plume into the sky
1pm: Magma Indonesia said that the eruption began at 5.05pm local time and grey plume has been seen rising as high as 700m above the peak.
An update issued today said: “The blasting ash is blowing weakly towards the east-southeast. The eruption is still ongoing.”
12.55pm: The aviation colour code from the Agung Volcano Observatory has updated to orange.
12.45pm: The National Disaster Management Agency has described the eruption as “phreatic”.
The USGS said: “Phreatic eruptions are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits (for example, tephra and pyroclastic-flow deposits).
“The intense heat of such material (as high as 1,170 ° C for basaltic lava) may cause water to boil and flash to steam, thereby generating an explosion of steam, water, ash, blocks, and bombs.”
Bali volcano is erupting after long period of seismic activity

The alert level at the popular tourist destination remains at Level 3 after it was downgraded from Level 4 on October 29.
Authorities are however monitoring the situation and any seismic activity in advance of a full-blown eruption.
