Table of Contents

Volcanic activity represents a great hazard for rising populations and international air traffic over volcanic regions. This book consists of the collection of papers devoted to monitoring volcanic activity with seismic, acoustic, geodetic, and video observations, and the catalogs of volcanic eruptions. The volcanoes, representing the subject of these observations (Bezymianny, Etna, Karymsky, Kizimen, Sakurajima, Sheveluch, Stromboli, Popocatépetl, Puracé, Volcán de Colima), are between the most active on our Earth. A special attention is applied to quantification of volcanic explosions from the seismic and acoustic records and the estimation of the height of eruption plumes of Vulcanian explosions from the seismic records. Monitoring volcanic eruptions and their forecasting based on the changes in the spectral characteristics of volcanic tremor, on the statistical analysis of appearance of Strombolian explosions, and on the analysis of historical eruption time series are discussed. The process of lava dome building in the crater of volcano and associated deformation of volcanic edifice derived from continuous geodetic and video observations is a subject of this book also. Analysis of the resolution of different-scale geodetic observations at the active volcano, using remote sensing and ground-based techniques during monitoring short-term volcanic events, such as Vulcanian explosions, and long-term volcanic events, such as the effusive and explosive stages of eruptions and the general tendencies in the development of the volcanic structure is done. Finally, this book reviews the seismic activity associated with the geothermal appearance of volcanic activity.

The book is addressed to the specialists in geology, geophysics, and volcanology as well as to the University students of these specialties. (Imprint: Nova)
