I've visited Anak Krakatau (during a quieter period) and have a piece of it on my bookshelf.
When you stand on the shore and look around at Rakata, Sertung and Panjang islands - the remaining fragments of the huge 1883 eruption - the sense of awe is almost overwhelming. You really feel you are standing on a pressure cooker and this small island, Anak Krakatau (the Child of Krakatau), is the valve ready to blow.
Indonesia is a wonderful, beautiful country...shaped the destructive power of the natural world.
