the air at 12:00 GMT at an elevation of 3–3.6 km
(10–12,000 ft).
Heading: West–northwest from the eruption site.
Colour: Light, low-lying clouds of steam observed over the eruption site, together
with occasional bursts of grey to black-coloured cloud, which rose to up to
half of the total height of the eruption plume. Above this level, the plume
was lighter in colour with a capping of white cloud

satellite data and running models to determine the sources of various

were 3 magmatic intrusions beneath Svartsengi and another beneath Krýsuvík
during 2020. Then one of the dykes started propagating to Fagradalsfjall region

(approx. 3 km high) and white when the flight arrived at Grímsvötn but at 20:55 GMT explosive activity increased again and the plume rose to about 7.5 km height. The increased activity was observed for about 20 minutes, then the activity dropped down at 21:15 GMT and increased again at 21:45 GMT. This pulsating activity is also clearly seen on tremor plots (click to enlarge) from near seismic
