I thought the "stay-indoors" alert was a hoax. I followed those links, and they seem pretty insubstantial. All it says is that some anonymous "UN official" says so-and-so.

Now there's a bit more meat to the bone from other sources. The source now has a name to it, seems credible - but still way out of proportions. It MAY come to a point where it would be advisable to stay indoors during ash fallout. Particular for people with airway issues.

Just business as usual. It may come to this, it may come to that... and then all you read in the headline is STAY INDOORS. As always I'm impressed by how the media distorts things to gain attention.
