The activity at the volcano continues at reduced rate. Steam explosions have been more intermittent and smaller during the past 2 days, generating plumes that rose a few hundred meters only.
This trend corresponds to the seismic signals showing a marked decrease since the surge of supply of magma that led to the paroxysm during 21-22 Dec, which accumulated lots of new lava. This in turn might have been "the last straw that breaks the camel's back", i.e. the additional sudden weight on the slopes and/or the shaking induced by the continuous explosions could might have been the final trigger for the landslide to occur.
The Indonesian Center for Volcanology and Geological Disaster Mitigation (PVMBG) published a first official estimate on the effects of the landslide:
- The summit of Anak Krakatau originally 338 meters high is now reduced to only 110 meters, i.e. most of the summit cone has indeed disappeared.
- As a consequence, Anak Krakatau island is no longer visible from the mainland, as the island of Panjang (Long Island) blocks the view from Java's west coast.
- The volume of the collapse is estimated to be between 150-180 million m3, while the remaining volume is currently estimated at between 40-70 million m3.
- For this reason, unless tectonic faults in the area of the Sunda Strait are activated, the risk of other massive landslides and tsunamis is currently deemed to be low.
