Pictures that were taken with radar cameras on board Coast Guard airplane TF Sif in the morning of April 14, 2010, a few hours after the volcanic eruption in Eyjafjallajökull began, provided scientists with a unique opportunity to monitor how cauldrons formed in the ice and meltwater broke its way through to the lagoon of Gígjökull.
“The face of evil”, a radar picture of Eyjafjallajökull taken by the Icelandic Coast Guard on April 15, 2010.
The sky was overcast and visibility poor in the first two days of the eruption and so the radar pictures proved very useful. They are featured in a recent article by Icelandic earth scientists in the Journal of Geophysical Research Solid Earth, ruv.is reports.
Radar pictures taken on April 15, 2010, garnered significant attention around the world as the three ice cauldrons in the crater were considered to look like the face of evil.
At the time, volcanic ash was emitted through the three cauldrons, while meltwater mixed with tephra flowed northwards to the Gígjökull lagoon.
