I've heard of that anecdote but I still am not sure why it applies to the whole of Europe, let alone England.
Is there even a standard for how much volcanic dust there can be before airports are closed? How do they know we're currently over the limit? If they answer is that they don't really know, how will they know when it's over?
- hugh3 17y agoAs far as I know there are no standards, but people are currently working very hard to figure some out.

- scorxn 17y agoCool that they released the photos. Any insight into what we're seeing there, and how it poses a risk?
- sampo 17y agoAs far as I understand, the volcanic ash melts in the combustion chamber (where temperature is like 1000 C), and then later can solidify on surfaces, and may block cooling ducts and such.
