Hekla eruption aviation risk warning
Iceland’s Hekla volcano poses a real threat to passenger jets, according to Professor of Geophysics at the University of Iceland, Páll Einarsson.
Despite written warnings from Einarsson to the Icelandic Transport Authority, transatlantic jets are still flying directly over South Iceland’s famous active volcano and are taking a “needless risk”.
The riposte is as usual and yet the good professor only suggests a tiny change in route… I’d keep well clear unless there is a jolly good reason, lot of space on long haul. Technically I can guess why, aircraft route between radio beacons.
The Talkshop routes between articles, volcanoes erupt from time to time. Icelandic are of especial interest given the proximity to the UK and the high sulphur content, both capable of influence here. Some claim with historic reason for famine.
Note: “erupted regularly every ten years in the second half of the 20th century (1970, 1980-81, 1991, 2000).”. How odd given the Pause.
I’ve recently seen papers claiming volcanic eruptions cause cooling and cause warming, ho ho, what goes up must come down. Then there is the trail of surprised findings of Pinatubo not showing where I expected yet was supposed to have had a monumental effect. Erupted 15N, claimed gloabl effect, big trace reported far north, none in South Africa, a remark in a study there, couldn’t find a trace in most data. Nor have I found it so far in satellite area mapping. I’d expect this to originate near the volcano.
Actually I don’t buy much effect, I think it is an excuse for what is not known.
So okay, when is Hekla going to heckle?
