Excerpt from Bibliography of the Geology and Eruptive Phenomena of the More Important Volcanoes of Southern Italy By the time that the Geologists' Association paid its visit to Southern Italy in the months of September and October, 1889, the bibliography had grown to almost twice the size, and Lavis happily seized upon the occasion to publish it in 1891 as an appendix to the account of the excursion, which was reprinted from the Proceedings of the Association. The whole thus formed a valuable manual of information on the Volcanoes of Southern Italy. From that time onwards no opportunity was lost for working at this bibliography and endeavouring to render it as complete as such a work can ever be. When the war broke out, depriving him at once of his practice, he had determined to employ his enforced leisure from professional duties till happier times should return in systematically revising and augmenting the whole bibliography and in ransacking every available source with this object in view. His tragic death cut this project short, and all the loving labour of years of patient research seemed likely to be thrown away had not his family most felicitously conceived the idea of completing the work so far as might be possible and publishing it as a worthy offering to his memory.

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.
