There have been earthquakes and volcanoes ever since the world began. It's part of the cooling/contraction process. With all the modern high tech communication we are just hearing more about it. The latest dust cloud problem from Iceland makes me wonder why people are so obsessed with flying all over the place. Although most people understandably go through a phase in life of wanting to see the world, and many have to travel for business reasons, I can't help feeling that a lot of it is quite unnecessary. Tough luck for the airlines.
