On the new map prepared by the Institute of Meteorology on January 16, 2024, a newly formed graben can be seen on the eastern side of the older graben. It stretches south to the sea through the eastern part of the city. Sunday's eruption occurred on the western, i.e., the left side of an older tectonic fault [which formed in November 2023].
The data we have compiled shows that new fissures have formed in the eastern part of Grindavik. Of course, there were old cracks, but now they have tightened. In the city's eastern part, the surface sunk by 1.4 meters.
The extension, or deformation, of the new graben is 1.4 metres. Scientists believe the amount of magma flowed from Svatsengi into the magma corridor on Sunday as during the December 18 eruption. It is believed that the volume of magma reached 11-12 cubic metres.
Kristín Jónsdóttir says that the future of Grindavik and seismic activity in Grindavik is very uncertain. No one can predict whether there will be another magma intrusion, whether it will move north or south, or another eruption.
So, can we say that as of Sunday, Grindavík has never been as dangerous as it is now?
“Yes, I would say yes,” says the volcanologist.
