Krakatau volcano (Sunda Strait, Indonesia): new series of paroxysms, lava flow entered sea, alert status raised to 3

 

The strong eruptive episode (likely to be classified as paroxysm) is now in progress at the volcano even at the time of this update.

Strombolian activity started to pick up rapidly at the summit vent in the evening of 22 April with detected precursor. The activity quickly intensified, accompanied by a sharp peak in volcanic tremor indicating rapid magma flux towards the surface resulted in a new lava-fountaining episode (paroxysm). The pulsating lava fountains have been shooting glowing scoria into the sky and continued to generate ash-rich plumes up to 20,000 ft (6,100 m) altitude drifting S-SE yesterday.
An accelerated seismic activity pushed a new batch of magma in the crater (being erupted as lava on the surface) that started to descend on the western slope (satellite image from 24 April) at 12:19 local time yesterday and made it to the sea.
Sulfur dioxide (SO2) emissions reached to a 9219 tonnes/day yesterday.
The local observatory raised the alert level for the volcano to Level 3 valid from 18:00 local time today.

UPDATE 4/28:

The explosive-effusive eruption at the volcano continues.
The latest image (27 April) captured by the Sentinel-2 satellite from Copernicus depicts the active lava flow, spreading into a new field of lava covering the origin land, and it is unclear whether it has already to built a new lava delta, but it looks as if has.
Judging from the surveillance webcam on 25 April, a new spatter cone has formed from the recent paroxysm activity.
The volcanic tremor decreased to medium-low values on 25 April.
