A pet peeve: if a mountain is spewing ash and/or lava, it is officially a volcano.
Also, I first saw the pictures from the first post this weekend and made the mistake of reading the comments (back when there were around 100 and not 708). Why oh why does every friggin' picture of nature inspire a flame war of "look how Mother Earth is hurting" vs "there is no such thing as pollution"? Seriously. This is getting tedious.
