Katla is rumbling a bit.
Historically, Katla tends to erupt 1-2 years after any eruption in Eyjafjallajökull.
Katla eruptions are also, historically, very nasty, very dangerous and likely to have wide (continental scale) impacts.
But not always.
Katla is the primary motivator for Iceland’s rather excellent Civil Defence System.
Earthquakes in last 48 hours under Mýrdalsjökull.
Definitely something stirring under there.
Will need to keep an eye on that, could go burp.
