The eruption of Laki is one of history`s great untold natural disasters. The eruption, spewing out a poisionous fog, lasted for eight months, but its effects lingered across Europe for years, causing the death of people as far away as the Nile, & creating famine that may have triggered the French revolution. Island on Fire is the story not only of a volcano but also of the people whose lives it changed, such as the pastor Jon Steingrimsson, who witnessed & recorded the events in Icel&. It is the story, too, of modern volcanology, & looks at how events might work out should Laki erupt again in our time.
