I know this isn't actually about volcanoes but it's all plate tectonics so I think I can bend the rules a little.
Earthquakes in London was an excellent play that I saw at the national theatre at the weekend, amongst other things it was about social breakdown, climate change and a massive earthquake in the capital. Like many people said about the recent Eyjafjallajoekull eruption this earthquake was seen as a punishment in result of our abuse to the world. Showing us how weak and insignificant we are compared to nature, which is either a very comforting or depressing thought. I'm personally quite reassured by the fact that nature can continue on without humanity and will grow and evolve to probably produce much more beautiful and interesting things. That to ecosystems we are insignificant and could just be wiped out by a massive earthquake, volcano or other natural disaster but life will continue. However I can kinda see how others find this depressing.
Anyway the play was absolutely brilliant had loads of really interesting issues and themes, brilliant performances and a killer soundtrack. Also while it was insanely sad, it did give me an uplifting feeling that everything was gonna be alright (but then I'd probably always think that if Do You Realize? by The Flaming Lips is the exit music)
