Volcanoes: Past and Present

by Edward Hull

"Volcanoes: Past and Present" by Edward Hull is a scientific publication written in the late 19th century. The book delves into the phenomena associated with volcanic activity and seismic events, comparing historical and modern eruptions while exploring the geological foundations behind these processes. At the start of the book, Hull provides a preface summarizing his objectives and outlining his approach to studying volcanic phenomena. He emphasizes that the text will focus on modern geological insights rather than being a comprehensive account of all volcanic activities. Hull states his intention to address significant questions regarding the nature of volcanic activity, while also discussing historical interpretations from ancient Greek and Roman thinkers. This introduction sets the stage for a deeper exploration of volcanic action, arguing for a continuity in the characteristics of eruptions throughout history, which will be further elaborated upon in the subsequent chapters.
