– We keep track of it. There was more activity than usual, says Kristian Løksa's head of communication at Avinor for E24 on Tuesday night.
On Monday at 01.41. The earth began shaking in the Myrdalsjöll area south of Iceland. Behind the ice is Katla – the largest volcano in Iceland.
The Icelandic Meteorological Institute recorded about 40 earthquakes during the night, the largest being 4.6 in force. It is not enough to give injuries, but the institute writes that the earthquake might feel in that area.
It can be the precursor of disease outbreaks
More seriously, earthquakes can be a warning to the outbreak of a huge volcano.
Katla had no outbreaks since 1918.
– If there is a break, there will be outbursts. We can not do anything about it, says Avinor.
Avinor regularly receives information from the Icelandic meteorological institute. So far they give "green light" to axial concentration, says Løksa.
Paralyzed air traffic in 2010
In the event of an outbreak, the situation may change rapidly. Katla is 10 times bigger than Eyjafjallajökull, which put "Europe's" rebellious "when it broke out in 2010.
The epidemic brought with it a huge cloud of ashes that was enhanced by cold water from the glacier during the eruption. The cloud contains glass particles that are dangerous to the aircraft – and are thus placed on the ground.
– When the ash crisis was a fact, everyone was dependent on aviation. It paralyzed most of the European air traffic for a few days. And big airline companies went on great losses, recalls Knut Morten Johansen's Director of Information at SAS at E24.
It's much better equipped today
Avinor argues that aviation is now "much better equipped" to handle stock clouds than in 2010.
– There was a lot on the international level for coordination of routines. Breaking the same size as in 2010 will have far fewer consequences for air traffic today, says Løksa.
SAS does not want to speculate on the latest activities in Iceland and says they relate to the messages of Avinor and the Norwegian aviation authorities.
"Quake means nothing for air traffic, but of course it is strictly followed by experts. It is also not the case that any epidemic must mean total paralysis of air traffic, notes Johansen.
