Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of 22 selected papers from the homonymous Conference held in September 2003 Milos, Greece. The aim of the conference was to serve as a forum for the presentation and constructive discussion of the state-of-the-art and emerging issues on the South Aegean Volcanic Arc. In the first part of the book the tectonic- geodynamic setting and the present upper mantle structure of the Aegean area are discussed. It includes an interesting interpretation of data on the spatial distribution of intermediate focal depth earthquakes, fault plane solutions and deep velocity structures, to further investigate active tectonics related to the deep structure of the southern Aegean volcanic arc. The second part deals with general volcanological, petrological and tectonic characteristics of the SAAVA presenting an extensive review of volcanological, chemical, isotope and tectonic data, using a large amount of new field and laboratory data. Interesting conclusions are presented regarding the present volcanic associations, the volcanic fields location and shape in respect to the large tectonic lineaments and the plate motions, the source of the SAAVA parental magmas. Presented in the third part is an extensive review on the volcanic hazard assessment and the monitoring state of the SAAVA centers. Seismic and geodetic monitoring of the Santorini volcano and the recent (1995-1998) crisis of Nisyros volcano are presented and discussed. The last part deals with hydrothermal deposits and processes in the SAAVA, as well as products and processes in adjacent areas with a particular interest and significance that link them to the SAAVA processes.*Systematic re-evaluation on the geodynamic and tectonic setting of the Aegean active volcanic centers *Thorough review with new data and ideas on the magma source region, the magma differentiation processes in both the deep and shallow levels, and the volcanological processes related both to the magma composition and storage depth as well as to the tectonic regime of the volcano growth area*Up to date estimation of the volcanic hazard in the Aegean area, and a detailed presentation of the present state and the monitoring efforts of the South Aegean active centers

Download or read book Nisyros Volcano written by Volker Jörg Dietrich and published by Springer. This book was released on 2017-08-22 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first compilation of scientific research on the island of Nisyros, involving various geoscientific disciplines. Presenting a wealth of illustrations and maps, including a geological map of the volcano, it also provides valuable insights into the geothermal potential of Greece. The island of Nisyros is a Quaternary volcano located at the easternmost end of the South Aegean Volcanic Arc. The island is nearly circular, with an average diameter of 8 km, and covers an area of approximately 42 km2. It lies above a base of Mesozoic limestone and a thin crust, with the mantle-crust transition located at a depth of approximately 27 km. The volcanic edifice of Nisyros comprises a succession of calc-alkaline lavas and pyroclastic rocks, as well as a summit caldera with an average diameter of 4 km. Nisyros marks the most recent volcano in the large prehistoric volcanic field between Kos-Yali-Strongyli-Pyrgousa-Pachia-Nisyros, where the largest eruption (“Kos Plateau Tuff”) in the history of the eastern Mediterranean devastated the Dodecanese islands 161,000 years ago. Although the last volcanic activity on Nisyros dates back at least 20,000 to 25,000 years, it encompasses an active hydrothermal system underneath the volcano with temperatures of roughly 100°C at the Lakki plain, the present-day caldera floor and 350°C at a depth of 1,550 m. A high level of seismic unrest, thermal waters and fumarolic gases bear testament to its continuous activity, which is due to a large volume of hot rocks and magma batches at greater depths, between 3,000 and 8,000 m. Violent hydrothermal eruptions accompanied by major earthquakes occurred in 1873 and 1888 and left behind large, “world-wide unique” explosion craters in the old caldera. Through diffuse soil degassing, the discharge of all hydrothermal craters in the Lakki plain releases 68 tons of hydrothermal-volcanic derived CO2 and 42 MW of thermal energy per day. This unique volcanic and hydrothermal environment is visited daily by hundreds of tourists.

Download or read book Geothermal Systems and Energy Resources written by Alper Baba and published by CRC Press. This book was released on 2014-03-07 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the region comprising Turkey and Greece, people have been using water from geothermal sources for bathing and washing of clothes since ancient times. This region falls within the Alpine-Himalayan orogenic belt and hence is a locus of active volcanism and tectonism and experiences frequent seismic events. This volcanic and tectonic activity has given rise to over 1500 geothermal springs. Its importance was recognized decades ago and the geothermal water is now being utilized for district heating, industrial processing, domestic water supply, balneology and electric power generation. The geothermal potential in this region is large. In Turkey alone it is estimated to be more than 31500 MWt while the proven potential is 4078 MWt. At present 2084 MWt is being utilized for direct applications in Turkey and 135 MWt in Greece. In Turkey electricity is produced for 166 MW installed capacity, whereas in Greece geothermal energy is presently not used for electricity production despite its potential. This book discusses the geochemical evolution of the thermal waters and thermal gases in terms of the current volcano-tectonic setting and associated geological framework that makes the region very important to the geothermal scientific community. The book explains, in a didactic way, the possible applications, depending on local conditions and scales, and it presents new and stimulating ideas for future developments of this renewable energy source. Additionally, the book discusses the role(s) of possible physicochemical processes in deep hydrothermal systems, the volatile provenance and relative contributions of mantle and crustal components to total volatile inventories. It provides the reader with a thorough understanding of the geothermal systems of this region and identifi es the most suitable solutions for specifi c tasks and needs elsewhere in the world. It is the fi rst time that abundant information and data from this region, obtained from intensive research during the last few decades, is unveiled to the international geothermal community. Thus, an international readership, in the professional and academic sectors, as well as in key institutions that deal with geothermal energy, will benefit from the knowledge from geothermal research and experiences obtained from the Aegean Region.

Download or read book Volcanism in the Campania Plain written by and published by Elsevier. This book was released on 2006-08-24 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with the study of three important volcanisms in the Campania Plain: Vesuvius, Campi Flegrei and Ignimbrites. The knowledge of the volcanic evolution of Vesuvius and Campi Flegrei has a particular relevance because of the hazards that these volcanoes pose to the about 1.5 million people living in the Neapolitan area. The contributors to the volume bring new data (experiments on volatile solubility, fluid-melt inclusions, tectonic, geophysical, isotope, geochronology), which are helpful in the creation of new models for a better understanding of the behaviour of the volcanic systems. In particular a hydrothermal model is used to explain the ground movements (bradyseism) at Campi Flegrei. To develop such a model, the authors use an analogue for the evolving Campi Flegrei sub-volcanic system, the model of the porphyry mineralized systems. For Campanian Ignimbrite the authors highlight the impact crystal-liquid separation has on melt compositional evolution and particularly focus on trace element and Th isotope evidence for open-system processes in the magma body associated with the Campanian Ignimbrite. The authors, for their interpretations, utilize thermodynamic and quantitative mass balance modelling of major and trace element data and semi-quantitative limits on Th and Sr isotopes to evaluate the role of crytal-melt separation, magma-fluid interaction, and assimilation of wallrock on the geochemical evolution of the Campamian Ignimbrite.
Download or read book Caldera Volcanism written by Joachim Gottsmann and published by Elsevier. This book was released on 2011-09-22 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume aims at providing answers to some puzzling questions concerning the formation and the behavior of collapse calderas by exploring our current understanding of these complex geological processes. Addressed are problems such as:- How do collapse calderas form? - What are the conditions to create fractures and slip along them to initiate caldera collapse and when are these conditions fulfilled? - How do these conditions relate to explosive volcanism?- Most products of large caldera-forming eruptions show evidence for pre-eruptive reheating. Is this a pre-requisite to produce large volume eruptions and large calderas?- What are the time-scales behind caldera processes? - How long does it take magma to reach conditions ripe enough to generate a caldera-forming eruption?- What is the mechanical behavior of magma chamber walls during caldera collapse? Elastic, viscoelastic, or rigid? - Do calderas form by underpressure following a certain level of magma withdrawal from a reservoir, or by magma chamber loading due to deep doming (underplating), or both?- How to interpret unrest signals in active caldera systems?- How can we use information from caldera monitoring to forecast volcanic phenomena?In the form of 14 contributions from various disciplines this book samples the state-of-the-art of caldera studies and identifies still unresolved key issues that need dedicated cross-boundary and multidisciplinary efforts in the years to come. - International contributions from leading experts - Updates and informs on all the latest developments - Highlights hot topic areas and identifies and analyzes unresolved key issues

Download or read book Paleomagnetic Rotations and Continental Deformation written by Catherine Kissel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most interesting results obtained in the last two decades in the study of crustal deformation has been the recognition that large regions of continental crust undergo rotations about vertical axis during deformation. Proof of such rotations has come through the paleomagnetic studies, which reveal rotations when paleomagnetic declinations within the deforming region arc compared with those found in coeval rocks in the stable regions outside the deforming zone. Such rotations were first described in Oregon then in the North American Cordilleras and in Southern California and were a surprise to everyone. Even in California which, as a result of oil exploration, was among the best geologically explored regions in the world, no one could claim to have predicted that these rotations would be found. Rotations have subsequently been found in other areas of recent continental tectonic activity, notably in the Basin and Range province, New Zealand, the Andes, Greece and Western Turkey, so that they appear as an important feature of continental deformation.

Download or read book Santorini written by Walter L. Friedrich and published by Aarhus Universitetsforlag. This book was released on 2009-10-27 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the Greek island of Santorini, classically known as Thera, erupted dramatically in 1613 BC (+/- 13 years), it produced one of the largest explosions ever witnessed, thereby possibly giving rise to the legend of Atlantis. This so-called 'Minoan' eruption triggered tsunamis that devastated coastal settlements in the region, and on Santorini it left behind a Bronze Age Pompeii, which is currently being excavated. Thriving Bronze Age settlements on the island - rich in colorful wall paintings and highly sophisticated pottery - were buried under thick layers of volcanic ash. The ejection of an immense volume of dust into the atmosphere also altered global climate for several years. The author, a well-known geologist, blends the thrill of scientific discovery with a popular presentation of the geology, archeology, history, peoples, and environmental settings of the island group of Santorini. He not only gives a comprehensive overview of the volcanic island and its past, but also reports on the latest discoveries: The finding, for example, of the olive trees which had been buried alive by the Minoan eruption has made it possible now to give a direct and precise radiocarbon date for the volcanic catastrophe. Furthermore, he seeks to assign certain geological structures, such as faulted rocks, red lavas and harbor sites, as depicted on the Bronze Age frescos from Santorini, to still-existing details in the Santorini landscape of today. Excellent color photographs and illustrations along with easily understandable scientific and historic details will make this book highly appealing to a wide audience. It will also be useful as a supplementary text for introductory courses in earth and atmospheric science, geology, volcanology, and paleoclimatology, as well as ancient history and archeology.
