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]

Comparing the data, they were able to calculate how the shape of the volcano changed due to the intrusion of the magma, which in parts rose to the surface through the new eruptive fissures, and in parts became "stuck" as shallow and deeper intrusions. The results are stunning:
- the western slope of Etna has moved 30 centimeters to the west (in red on the map, figure c); [less]

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]
