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:

Thuban is a former Pole Star | Brightest Stars Thuban is not a particularly bright star, but it holds a special place in the hearts of stargazers. That’s because Thuban was the Pole Star some 5,000 years ago, when the Egyptians were building the pyramids. Among the many mysteries surrounding Egypt’s pyramids are the so-called “air shafts” in the Great Pyramid of Giza. These narrow passageways were once thought to serve for ventilation as the pyramids were being built. The Great Pyramid of Giza, an enduring monument of ancient Egypt. This diagram shows the so-called air shafts in the Great Pyramid. One of the “air shafts” follows a crooked course through the Great Pyramid, so you couldn’t have sighted stars through it. The 26,000-year precession cycle causes the north celestial pole to move counter-clockwise relative to the backdrop stars. Earth never changes its axial tilt, but its axis does point out at different pole stars. Indeed, Thuban at times made a better pole star than our modern Polaris. How to see Thuban.
