Book excerpt: Subduction zones consume oceanic lithosphere and are an indispensible part of plate tectonics. Unlike the oceanic lithosphere production system which can be linked as a nearly continuous, albeit sinuous, strand around the earth, subduction zones are a rather dissociated group and are found in several isolated corners of the world. While plate tectonics can predict that subduction zones are required along certain plate boundaries, it does not stipulate how subduction zones initiate and develop. The preservation of newly created oceanic lithosphere and the propensity for spreading centers to fragment continents leaves a wealth of geological informa tion on the initiation and evolution of spreading. On the other hand, the subject of subduction initiation has little observational basis. To find such observations, we need to look at some muddled tectonic regimes. The Macquarie Ridge complex presents a natural laboratory for studies of subduction initiation. 2. Tectonics of the Macquarie Ridge Complex The Macquarie Ridge complex is a complicated physiographic feature that trends approximately north-south between South Island, New Zealand and the Pacific-Antarctica spreading center. This feature consists of a sequence of troughs and ridges, with Macquarie Island as the only exposed expression. The seismically active Macquarie Ridge complex (hereafter: MRC) is crudely continuous with the Tonga-Kermadec-New Zealand seismic activity. The basic physiographic features and seismicity of the MRC are shown in Figure I. The earthquake epicenters generally cluster about the bathymetric expression of the MRC.

Download or read book The Chilean Earthquake and Tsunami 2010 written by Luz A. Cardenas-Jiron and published by WIT Press. This book was released on 2013 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses the last Chilean earthquake which occurred on 27th February 2010. It happened at the end of summer vacations reaching a magnitude of 8.8 Mw with its epicentre in Cobquecura, in the Bío- Bío region. This phenomenon mainly affected the central Chile area which comprises of the regions of Araucanía, Bio-Bio, Maule, General O´Higgins, Valparaíso and Metropolitan. At that date it was the fifth largest earthquake ever to have occurred on a worldwide scale. The book is organized in six chapters written by remarkable authors from different disciplines thus presenting a comprehensive view of the occurrence. The texts come from the fields of geophysics, hydro-mechanical engineering, telecommunication, geographic information systems, urban and design planning, building engineering, architecture and urbanism. Authors come from academia and the public and private sectors to give an idea of complementary approaches that range from theoretical descriptions to practice and emergency solutions. It will be suitable for professionals and researchers taking decisions, undergraduate and postgraduate students and teachers at university levels.
Download or read book Mega Earthquake Tsunami on the Pacific Coasts written by Rodrigo Larenas and published by Createspace Independent Publishing Platform. This book was released on 2010-06-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mega-earthquake occurred on February 27 of March 2010, along the coast of the central Chile in South America, produced an early and shacked weak up to millions of people. The 8.8 Richter scale event hit the central zone at 03:34 A.M. while people were sleeping. Then, as if the damage weren't enough and still at dark, it was followed by a not only devastating but also lethal tsunami that was strong enough to travel across the Pacific Ocean, hitting Asia only fourteen hours after. This earthquake is the fifth more intense ever measured and it was so strong that Scientific American published in the March 4th newsletter the following article: "The magnitude 8.8 earthquake that jolted Chile on Saturday was felt as far away as São Paulo. But NASA scientists are proposing that its repercussions are truly global in a geophysical sense: it likely shifted Earth's axis by about eight centimeters." But unfortunately the tragedy didn't stop with the earthquake. It also originated a tsunami that hit the coast with 4 waves, the first arriving just a few minutes after the earthquake and the last, several hours after. This tsunami was so strong that it has been detected that at least one wave was 30 meters or 98 feet high. Before continuing I would like to prevent lecturers from falling into the temptation of thinking that this mega-nature-events, only happen in faraway lands affecting people quite different from us. The Indonesian Tsunami of December 2004 was very distant from Chile not only in miles but also in cultural terms. And now, it's clear that Indonesian experience helped to prevent more fatalities. That's why this book has been written to urge people living in the Pacific Rim, to take some time to analyze their situation, the one of each community and act in order to prevent or reduce potential damages and casualties.
