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 on 22 Dec 2018, which had triggered a deadly tsunami that killed hundreds of people on Java's west coast.
Video and chronology of the eruption:
The eruption produced a significant SO2 plume that can be seen on satellite data:

Krakatau volcano (Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 April-14 April 2020 (New Activity / Unrest)
PVMBG reported that at 2158 and 2235 on 10 April an eruptive event at Anak Krakatau generated dense white, gray, and black ash plumes that rose as high as 2 km above the summit and drifted S and E. The events were followed by Strombolian activity that ejected incandescent material onto the crater floor and summit areas; video revealed lightning visible in the ash cloud. The Darwin VAAC issued a notice at 0145 on 11 April stating that an eruption plume had risen to 14.3 km (47,000 ft) a.s.l., but noted low confidence in the altitude due to the possible mixing of the eruption plume with meteorological storm clouds. ...
