Crater Incandescence was observed at night.
Incandescence from the crater was detected at night.
Crater Incandescence was visible the morning of 27 March
and at night during 30 March-1 April.
The Incandescence(glow) is due to the high temperature volcanic gas emissions,
which become'visible' like this at night.
When a material is heated to Incandescence it emits light that is characteristic of the atomic makeup of the material.
The image(below)
taken yesterday around 10.00 p.m. local time shows the Incandescence(glow) that is visible from the current summit dome at night.
Based on BNPB and PVMBG reports, the eruption at Agung continued during 6-12 December,
with high seismicity and nighttime crater Incandescence often visible.
Observations on 24 May indicated flowing lava was mostly confined to tubes,
though a small area of Incandescence was visible at the main crater.
At 2200(~16.5 hours after the increased activity began), the eruption waned, with activity characterized by weak-to-moderate explosions,
crater Incandescence, and ash plumes that rose almost 800 m.
All other fissures are inactive, although observers on the late afternoon overflight noted abundant gas
emission from Fissures 9 & 10 and Incandescence without fountaining at fissures 16 & 18.
Harmonic tremor emerged on 27 June, and at 2221 an event generated an ash plume that rose 2 km above the crater rim and drifted W. Gas-and-ash emissions were continuous during 28-29 June,
rising around 2 km and drifting W and SW, and Incandescence was reflected in the plume;
