BBC - History - Pompeii: Portents of Disaster List of large volcanic eruptions in the 21st century This is a list of volcanic eruptions of the 21st century measuring a Volcanic Explosivity Index (VEI) of at least 4, as well as notable smaller eruptions. Note that the size of eruptions can be subject to considerable uncertainty. See also[edit] References[edit] External links[edit]

Volcano- EnchantedLearning.com A volcano is a place on the Earth's surface (or any other planet's or moon's surface) where molten rock, gases and pyroclastic debris erupt through the earth's crust. Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where lava erupts, and some are domes, shields, or mountain-like structures with a crater at the summit. Magma is molten rock within the Earth's crust. When magma erupts through the earth's surface it is called lava. Lava can be thick and slow-moving or thin and fast-moving. Rock also comes from volcanoes in other forms, including ash (finely powdered rock that looks like dark smoke coming from the volcano), cinders (bits of fragmented lava), and pumice (light-weight rock that is full of air bubbles and is formed in explosive volcanic eruptions - this type of rock can float on water). Volcanic eruptions can cause great damage and the loss of life and property. The Word Volcano: The word volcano comes from the Roman god of fire, Vulcan.

Global Volcanic Hazards and Risk Originally prepared for the United Nations Office for Disaster Risk Reduction, this is the first comprehensive assessment of global volcanic hazards and risk, presenting the state of the art in our understanding of global volcanic activity. It examines our assessment and management capabilities, and considers the preparedness of the global scientific community and government agencies to manage volcanic hazards and risk. Particular attention is paid to volcanic ash, the most frequent and wide-ranging volcanic hazard. Of interest to government officials, the private sector, students and researchers, this book is a key resource for the disaster risk reduction community and for those interested in volcanology and natural hazards. A non-technical summary is included for policy makers. Reviews:
