The main ash cloud traveled around the Southern Ocean about 3 times and Qantas and Jetstar airlines suspended flights from New Zealand's South Island to Australia for some time. Air New Zealand, however, decided to burn more fuel and fly below the cloud base. The Puyehue-Cordón volcano eruptions caused a great deal of grief here in New Zealand.

The current tentative date of reopening is August 31 (and we are in the middle of ski season). Airports in northern Patagonia have been on and off since the eruption. Even in Buenos Aires, as of last week, there have been airports closed because of volcanic ash there (Buenos Aires is 1500 km away). @Messier Tidy Upper: Bariloche Airport is closed since June 4.

Am sure that it won't stop and isn't causing climate change. Dramatic volcanic photo there. :-)

Am sure that it won’t stop and isn’t causing climate change.

The Scattered Disk is, I gather, outside the Kuiper belt - or more accurately the Edgeworth-Kuiper belt / Trans-Neptunean / cometary belt region and contains ice dwarfs like tenth planet Eris <i>(formerly "Xena" & catalogued as 2003 UB313.)</i> and possibly Sedna although the latter ice dwarf planet may instead belong to the inner region of the Oort cloud. As I understand it, the Edgeworth-Kuiper belt objects are in long-term stable orbits resonant with Neptune whereas the Scattered Disk Objects (SDOs) are not - and many of these eventually transition to the inner solar system becoming "Centaurs" and perhaps becoming either short-period comets, or getting captured to become moons of the gas giants or even getting ejected from the solar system by the gas giant planet's gravity. (Centaurs are objects orbiting between Saturn and Pluto named for the fact that the first one discovered - Chiron - and many others were named after mythical centaurs and are seen as half-cometary, half asteroidal in nature.) Short answer : The Scattered Disk region lies outside the Edgeworth-Kuiper belt but inside the Oort Cloud. But these regions may overlap to some extent. Click on my name for wiki-basics on the Scattered Disk. Hope that helps. :-) @ ^ lqd :

See my town, Bariloche, partially covered by fog at the shores of the lake? I covered the first weeks of the eruption in my blog (in Spanish, linked in my name). You are welcome to visit (both the blog and the city). I was surprised to find that part of the volcanic ash was magnetic. I has been both sad and beautiful.
