Over 30 years ago G. P. L. Walker wrote an article in Nature on excess spreading axes and spreading rate in Iceland. His statement that ‘the spreading rate is several times greater in part of Iceland than elsewhere on the Mid-Atlantic Ridge’ was immediately rejected and has rarely been discussed since. The problem of excess spreading in Iceland has appeared in various ways in the geological data obtained since that time. Here the drift (spreading half-rates) of several central volcanoes is studied to find out the behaviour of the spreading in Iceland. All the volcanoes seem to be drifting...

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.
