Krakatoa volcano (Sunda Strait, Indonesia): new cracks found on the island raise fears about possible new landslide and tsunami

While activity continues at Anak Krakatau island with little changes over the past day, Indonesia's Meteorology, Climatology and Geophysics Agency (BMKG) published a worrying observation: new cracks were discovered that run through the remaining island. It is feared that these could be precursory signs of new, potentially large-scale landslide events that could in turn trigger another tsunami.
According to the Head of BMKG, Dwikorita Karnawati, there are two new cracks in a straight line on one side of the Anak Krakatau island, possibly caused by the continuous shaking of the island due to the violent explosions occurring during the past 2 weeks since the catastrophic landslide on 22 Dec.
According to a news article, the new cracks are deep and emits steam and ash. If another collapse occurs along these cracks, it could involve a volume of estimated 67 million cubic meters of material. Even though it is a bit less than what the avalanche on 22 Dec removed (estimated to be around 90 mio cu m), it could still trigger a dangerous tsunami.

The volcano continues to erupt and generate large ash and steam plumes that rise to up to 45,000 ft (15 km) altitude. This indicates that the very explosive water-magma interaction continues, although recent satellite images show that the crater bay has almost filled with new deposits. ... [more]
