Forecasting the time, place, and character of a volcanic eruption is one of the major goals of volcanology. It is also one of the most difficult goals to achieve. Until recently, people living in a volcano's shadow had little help anticipating an eruption. A major volcanic event might strike with no warning at all. In the past 300 years, volcanic eruptions, most of them unexpected, have killed more than 250,000 people. In 2000, experts estimated that 500 million people were living in areas at risk from catastrophic volcanic eruptions. This book describes the strides that have made in eruption forecasting in recent years and explores why accurately predicting volcanic events remains difficult. Based on the methodologies in this book, Eruption Pro 10.6, to our knowledge, it is the only software programme of its type anywhere in the world. Eruption Pro 10.6 performs analysis on current available volcano eruption data from both historical and current available eruption data, near real-time measurement data including, seismic, deformation, thermal, frequency of eruption analysis, solar & lunar influences, crater lake temperature (if applicable), COSPEC, & statistical procedures. The newest version also accounts for, albeit very small, contributions due to lunar and solar influences.
