Krakatau, a small island group in the Sunda Strait between the islands of Sumatra and Java is one of the world's most famous volcanoes. It is a mostly submerged caldera with 3 outer islands belonging to the rim and a new cone, Anak Krakatau, that has been forming a new island since 1927 and remains highly active.
Krakatau exploded spectacularly in a devastating Plinian eruption 1883 that killed more than 30,000 people (mostly by the huge tsunamis triggered by the eruption). The eruption was one of the first global news events after telegraph lines had connected the different continents.

At 00:26 local time, seismic instruments showed an eruption signal lasting about 2 and a half minutes. ...màsLater in the day, a steam plume could be seen rising from the island group. A small thermal signal is present on satellite data. At the moment, it is unclear whether this is a sign of a new eruptive phase or remains as a single, isolated event. The alert status of Krakatoa remains at 3 ("Siaga", on a scale of 1-4). [ Menos] [ leer todo] dom, 13 ene 2019, 14:27

Surviving fishermen who were in the caldera at the time of the event reported seeing massive waves sweeping over the entire, lower island of Sertung (west of Anak Krakatau), estimating them to be about 25 m in height.

Krakatoa seen this afternoon at sunset - the plume from Anak Krakatau is visible as a dark looming shadow (image: VSI webcam) 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. ...màsAccording 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.

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. ...màs( Link to high-res satellite images published on BBC) If activity continues, it can be expected that soon the sea water will be cut off from the vent. At that point, activity can be expected to change towards purely magma-driven (with no or less water involved), in the form of lava fountains, strombolian explosions and possibly lava flows.

Our correspondent Doni Janskulo from Kalianda, Lampung, took advantage of very clear views yesterday and managed to take some of the most extraordinary and dramatic footage yet of the explosions on collapsed Anak Krakatau island. ...màsEven though it is from 40 km away, it shows the activity in amazing detail. It takes place at the island of Anak Krakatau, hidden from view now behind Panjang island seen in the foreground. The active vent is now under water and lets sea water interact violently with the rising magma: the result is so-called Surtseyan activity, a type of volcanic eruption that takes place in shallow seas or lakes, named after the island of Surtsey which appeared off the southern coast of Iceland and had this activity in 1963. In this video, very powerful explosions can be seen generating jets of ash, debris, steam and water to several hundred meters ("rooster tails") radially from the explosion point.
