Description of Active and Extinct Volcanos, of Earthquakes, and of Thermal Springs

Charles Daubeny (1795–1867) first published Active and Extinct Volcanos in 1826. This reissue is of the second, augmented edition of 1848, which the author explains was significantly updated in the light of the work of Charles Darwin. Part I contains geological descriptions of most of the world's known volcanos, arranged by region, many of them based on Daubeny's own observations. Part II contains descriptions of earthquake-prone regions, thermal springs, and thermal waters. In Part III Daubeny introduces his influential theory of the causes of volcanic action, proposing that it results from contact between water and metals beneath the earth's surface. He also discusses the factors that give volcanos particular characteristics, and the impact of volcanos on their environments. This pioneering work of Victorian geology provided the scientific community with some of the first descriptions and data sets on previously unstudied volcanic regions, and is still referred to today.
