"California is the most populous state in the nation and has attracted immigrants since the gold rush in 1848, whether by accident or intention. Although California also has more natural hazards per square mile than any other state as a result of straddling a plate boundary and because of its geologic adolescence, this hasn't deterred others from moving here. In addition to active faults and earthquakes, the state has a myriad of other natural hazards that frequently wreak havoc on the state and its residents, whether floods, landslides and debris flows, sea-level rise and coastal erosion, an occasional tsunami, and now we have climate change with its more frequent droughts and wildland fires, and more concentrated winter rainfall. This book is about the state's vulnerability to natural hazards, why and where we have these events, what has happened in the past and what we can anticipate in the future. And no place in the state is far from one natural hazard or another. Most Californians have an innate interest in these events and not many years goes by without a catastrophe of one sort or another, which can affect entire towns or regions. California Catastrophes is the only book focused on the natural disaster history of the state"--

Volcanic eruptions are common, with more than 50 volcanic eruptions in the United States alone in the past 31 years. These eruptions can have devastating economic and social consequences, even at great distances from the volcano. Fortunately many eruptions are preceded by unrest that can be detected using ground, airborne, and spaceborne instruments. Data from these instruments, combined with basic understanding of how volcanoes work, form the basis for forecasting eruptionsâ€"where, when, how big, how long, and the consequences. Accurate forecasts of the likelihood and magnitude of an eruption in a specified timeframe are rooted in a scientific understanding of the processes that govern the storage, ascent, and eruption of magma. Yet our understanding of volcanic systems is incomplete and biased by the limited number of volcanoes and eruption styles observed with advanced instrumentation. Volcanic Eruptions and Their Repose, Unrest, Precursors, and Timing identifies key science questions, research and observation priorities, and approaches for building a volcano science community capable of tackling them. This report presents goals for making major advances in volcano science.
