The eruption of the volcano continues with no signs of weakening. Rather a slight increase in the number of reported explosions and the intensity of the heat signal can be noted on satellite data and the reports from the observatory on the coast who analyze the seismic data.
Whether the lava flow observed by Galih and his group 2 weeks ago is still active is currently unknown, but we will soon visit the volcano and report our eye-witness account afterwards. If you like to join a small team of VolcanoDiscovery, there are still 2 spots available for the Krakatau Volcano Special from 15-20 Oct.
VAAC Darwin reports near continuous ash emissions to 7-10,000 ft altitude drifting in various directions, visible on satellite data.
