Explosive eruptions have the potential to distribute ashfall across large areas, resulting in physical and chemical impacts to infrastructure essential for society's normal functioning, causing disruptions of service which may lead to economic and psycho-social impacts to communities. This book provides a state-of-the-art review of information on impacts to critical infrastructure from volcanic ashfall, and how damage can be minimized. The book is an essential text for building awareness of likely impacts and providing possible mitigation options. As such, it is likely to appeal to infrastructure companies, Government, local authorities and the wider hazard management community charged with hazard mitigation. Where feasible a semi-quantitative approach has been adopted. This will indicate potential costs of such events and how much can be saved by effective mitigation.
