Earthquakes And Volcanoes

"A Weldon Owen production"--P. facing t.p.

Discover the Earth's most explosive volcanoes and what it's like to experience an earthquake feels like in this picture-led guide to the hotspots of the world This book tells you everything you need to know about the Earth's most extraordinary natural forces - from active volcanoes, including Kilanea in Hawaii and Etna in Italy, to devastating earthquakes that have hit San Francisco and Japan. Discover how the eruption of Mount Vesuvius devastated the cities of Pompeii and Herculaneum, but left in its wake remarkably preserved treasures. Find out, too, how dogs can search for survivors in the aftermath of a huge quake. Eyewitness Volcano and Earthquakeexplores how tectonic plates collide, what causes magma to escape from deep inside Earth and why eruptions affect our weather. Learn how scientists predict and measure the magnitude of earthquakes, and find out what a volcanologist does. Packed with striking full-colour photographs and illustrations of lava flows, pyroclastic clouds, rocks and precious stones, preserved bodies and petrified objects, and much more along with amazing facts, infographics, statistics, and a timeline to reveal the most devastating volcanoes and earthquakes in history. Part of DK's best-selling Eyewitnessseries, which is now getting an exciting makeover, this popular title has been reinvigorated for the next generation of information-seekers, with a fresh new look, new photographs, updated information, and a new "eyewitness" feature - fascinating first-hand accounts from experts in the field.

Discusses the structure and movement of the earth's surface, and describes earthquakes and volcanoes, how they are measured, and their aftereffects.

Explains and illustrates volcanic structures, products and processes, with worked examples and exercises, for students and professionals.

This book is part of the Nature Company Discoveries library, a dynamic new reference series for children. Atmospheric illustrations, strong photographs and lively text engage and encourage readers to discover for themselves the world around them. A four-page foldout in each title reveals a dramatic, and perhaps unexpected, perspective.

Combines facts with photographs of volcanoes and earthquake-affected regions to introduce readers to such topics as underwater volcanoes and plate tectonics while offering insight into the world-changing power of natural disasters.

Spine title: Volcanoes, earthquakes, and powerful storms. Examines the greatest forces of nature and explains what humans have learned from studying them.

Volcanic seismology represents the main, and often the only, tool to forecast volcanic eruptions and to monitor the eruption process. This book describes the main types of seismic signals at volcanoes, their nature and spatial and temporal distributions at different stages of eruptive activity. Following from the success of the first edition, published in 2003, the second edition consists of 19 chapters including significant revision and five new chapters. Organized into four sections, the book begins with an introduction to the history and topic of volcanic seismology, discussing the theoretical and experimental models that were developed for the study of the origin of volcanic earthquakes. The second section is devoted to the study of volcano-tectonic earthquakes, giving the theoretical basis for their occurrence and swarms as well as case stories of volcano-tectonic activity associated with the eruptions at basaltic, andesitic, and dacitic volcanoes. There were 40 cases of volcanic eruptions at 20 volcanoes that occurred all over the world from 1910 to 2005, which are discussed. General regularities of volcano-tectonic earthquake swarms, their participation in the eruptive process, their source properties, and the hazard of strong volcano-tectonic earthquakes are also described. The third section describes the theoretical basis for the occurrence of eruption earthquakes together with the description of volcanic tremor, the seismic signals associated with pyroclastic flows, rockfalls and lahars, and volcanic explosions, long-period and very-long-period seismic signals at volcanoes, micro-earthquake swarms, and acoustic events. The final section discuss the mitigation of volcanic hazard and include the methodology of seismic monitoring of volcanic activity, the examples of forecasting of volcanic eruptions by seismic methods, and the description of seismic activity in the regions of dormant volcanoes. This book will be essential for students and practitioners of volcanic seismology to understand the essential elements of volcanic eruptions. Provides a comprehensive overview of seismic signals at different stages of volcano eruption. Discusses dozens of case histories from around the world to provide real-world applications. Illustrations accompany detailed descriptions of volcano eruptions alongside the theories involved.

Questions and answers provide information about volcanoes and earthquakes, covering such aspects as why, how, when, and where these phenomena occur.
