The eruption of Anak Krakatau has been confirmed.
One of Volcano Discovery readers spent a night on February 20, 2017, at Anak Krakatau and saw intense strombolian-vulcanian type activity from the summit.
First sign of volcanic activity of Anak Krakatau (Child of Krakatau) were observed via satellite imagery on February 17, 2017, where a strong thermal anomaly was discovered over the summit of the active volcanic peak.
Was Anak Krakatau entering a new eruptive phase?
The new suspected eruption was confirmed on February 20, 2017 by one of the reader of Volcano Discovery who says: ‘I spent last night on the Anak Krakatau and I just saw your post on a new activity, I can confirm that there was a lot of activity yesterday afternoon / night.‘
The above picture, supposed to have been taken on February 17th by Anugera Simanjuntak, shows a very clear plume rising from Krakatau’s crater.
A strong degassing plume is present. Recent eruptive materials have also been found on the flanks of the colossus, probably from the explosions of 17-18.
And the eruption could look like this:
PVMBG reported that seismicity at Anak Krakatau increased on 17 February. The first earthquakes indicating emissions were followed by continuous tremor. Harmonic tremor were first recorded February 19 at 18:10. Strombolian explosions ejected incandescent material 200 m high at 19:04.
