Krakatoa, also known has Krakatau, has reportedly erupted in Indonesia.
There are reports of a “large magmatic eruption” happening right now.
NZHerald reports that satellite imagery shows ash several kilometres into the air and SO2 plume reaching 15km in altitude. It also refers to webcam on Anak Krakatau Island showing lava fountaining from the volcano.
Volcano Discovery reports that a large magmatic eruption is taking place at the volcano right now. Based on satellite imagery, VAAC Darwin spotted a high-level ash and SO2 plume reaching 47,000 ft (15 km) altitude moving WNW.
A strong thermal hot spot is detected as well. Both the webcam on Anak Krakatau Island and from the coast (in 40 km distance) show strong lava fountaining from the volcano.
This seems to be the strongest eruptive phase since the violent phreatomagmatic activity following the partial collapse of the volcano in Dec 2018, which had triggered a deadly tsunami on 22 Dec 2018.
