Winchester veers between eyewitness accounts by survivors and the limited scientific measurements of the time in an attempt to describe the indescribable. The event "is still said to be the most violent explosion ever recorded and experienced by modern man", he writes. "Six cubic miles of rock had been blasted out of existence, had been turned into pumice and ash and uncountable billions of particles of dust." Yet words and numbers can barely hint at the scale of the calamity, which resulted in tsunamis that washed whole villages into the ocean and forever changed the very topography of the area.

The author also explores the social and cultural topography, noting that "Orthodox Islam, its revival in part triggered by tragic events such as the great cataclysm, was totally transformed in Java during the nineteenth century, with fundamentalism, militancy and profound hostility to non-Muslims its watchwords". At times Winchester seems to overstate his case, and the link he finds between Krakatoa and the rise of anti-Western sentiment in the Islamic world isn't especially convincing. But by weaving together the disaster with science, communications, politics, religion and economics, he has come up with a comprehensive and often fascinating glimpse into the way the world, and our perception of it, can change in an instant. --Shawn Conner, Amazon.ca

Synopsis
The most terrifying and destructive volcanic cataclysm in modern recorded history took place in August 1883, when a series of incredibly powerful detonations destroyed the landmark island of Krakatoa, in the Sunda Strait, five miles off the western tip of Java. The impact of the explosions was utterly destructive in the immediate region, destorying 200 Javan villages and 40,000 people. The explosions had a dramatic effect that was felt and heard for thousands of miles, over fully ten per cent of the earth's surface - in central Australia, in East Africa, in India and in China. Ships sailing as far away as the Red Sea were covered with thick volcanic ash and immense rafts of pumice, some big enough to support trees and animals, floated in the seas clear across to Africa. Even more amazingly, the explosions were experienced around the whole world - by way of a substantial ten year burst of global warming - by the brilliance of sunsets and by the presence of fine suspended ash in the air. Using contemporaneous reports, this text recounts the events that led up to the cataclysm, as well as those occurring immediately after. Above all, Simon Winchester writes about how the Americans, English, Chinese and Dutch - and also the Javanese and Sumatrans to whom this land belonged - dealt with the unforgettable events of the day that their world exploded.
