An active lava dome is growing inside the summit crater of Krakatau volcano. Our tour expedition leader Andi just returned from a visit and reports that the dome is now about 100 m wide, and has 2 main active vents that eject jets of incandescent gas.
Seismic signals recorded on 26 March
At night, the glow from the dome is clearly visible from Rakata and Sertung islands, and a continuous intense solfatara plume is rising about 500 m above the summit. Andi and our group observed also that there are now more and larger fumarole fields on the southern part of the cone. According to our observations and the opinion of local scientists, this area is inflated due to the pushing of the lava dome.
The seismic recordings from the observatory of Krakatau also show an increase in activity. On 26 March, there were 138 volcanic-tectonic (A-type) earthquakes and 300 long-period (B-type) quakes alone.
The question is how long the lava dome remains quiet and purely effusive in style. Explosive, also larger vulcanian-type ones, activity could occur any time.
Krakatau (Anak Krakatau) volcano (Sunda Strait, Indonesia) activity update: Continuous steam/gas emissions reaching 100-500 m in height.. Lava glow lava at night. No eruptions.
