Textbooks in volcanology commonly emphasize the correlations observed between the volcanic and tectonic systems on Earth, implying direct cause-effect relationships between these two systems. When attention is focused on volcanic activity on other planets, moons and even asteroids, however, the causality implied by the correlations established on Earth becomes less evident. Questioning the cause-effect relationship between Tectonic and Volcanic systems on Earth constitutes the motivation to explore a different approach than that used in the past 30 years. In this paper I undertake this task based on a conceptual definition of a volcanic system that can be used regardless...

Studies in Volcanology: The Legacy of George Walker
Professor George Patrick Leonard Walker was one of the fathers of modern quantitative volcanology and arguably the foremost volcanologist of the twentieth century. In his long career, George studied a wide spectrum of volcanological problems and in doing so influenced almost every branch of the field. This volume, which honours his memory and his contributions to the field of volcanology, contains a collection of papers inspired by, and building upon, many of the ideas previously developed by George. Many of the contributors either directly studied under and worked with George, or were profoundly influenced by his ideas. The topics broadly fall under the three themes of lava flows and effusion, explosive volcanism, and volcanoes and their infrastructure.
