Even 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. [less]

A total of at least 7 vents are currently active (spattering, strong degassing and/or explosions) in the crater terrace.
The alert status of the volcano had been raised last week. [less]

Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 35000 ft (10700 m) altitude or flight level 350 . ...more [read all]

Italian scientists have analyzed satellite data from the Italian Cosmo-SkyMed and the European Sentinel satellites, which passed over Etna both before and after the short, but intense flank eruption that began on 24 December 2018 and the seismic crisis that accompanied this event and culminated in the 4.8 magnitude early on 26 Dec with an epicenter near the villages Viagrande, Trecastagni and Fleri on the southeastern side of Etna. ...more [read all]

The activity at the volcano remains above average. Our colleague Marc Szeglat (www.vulkane.net) reported that continuous spattering, in addition to sometimes relatively strong strombolian explosions, can often be seen from from the NE vent. ...more [read all]

The volcano observatory raised the alert status of the volcano to 2 ("Waspada" on the Indonesian 1-4 scale), as an increase of volcanic earthquakes and fumarolic activity had been observed during the past week. ...more [read all]

Sometimes strong explosive activity seems to continue at the volcano: VAAC Darwin reported an ash plume that rose to 40,000 ft (12 km) altitude this morning as well as "regular, intermittent" emissions of volcanic ash to 35,000 ft (10 km). ...more
