Eyjafjallajokull

As I've mentioned, I will be giving a talk here at Denison on the Eyjafjallajökull eruption and how the events unfolded on the internet - specifically, I'm interested in the idea of the general public taking an active role in volcano monitoring. So, I have a request from Eruptions readers - and by no means do you have to take part. However, if you are willing, I'd like to know your professional/"day job" and your geologic background - be sure, I will not use your real name or connect your Eruptions pseudonym to any information you send. I am just looking to get a hold on the backgrounds of…

Some news for a sleepy Monday: Mt. Hood in Oregon. The ash from Eyjafjallajökull is, once again, causing significant airspace closure over northern Europe - close of 1,000 flights today. However, much of the closures are fairly short-lived, but that isn't keeping people happy. The eruption hasn't actually changed much, just that the winds are bringing ash towards Europe. The ash for the next few days will likely effect the England, Scotland, Ireland, Netherlands, France and possibly other parts of northern Europe (along with airspace over Greenland and the north Atlantic). The ash plume is…

[UPDATE: readers should be aware of a correction on the source site. The best estimate of CO2 is in fact 150,000 tons per day, not 7400, with a possible maximum of 300,000 tons per day. So the graphic is much less compelling, but the story of Joe vs the Volcano is not affected.] Even if I can't say it, the volcano Eyjafjallajokull is great to illustrate just how ludicrous the "Volcanoes emit more CO2" argument is. Courtesy of Information Is Beautiful, here is a very telling graphic. Is there really a need to say more?
