    Schlagwort(e): Tsunami ; Indian Ocean
    Beschreibung / Inhaltsverzeichnis: Ten years ago, on December 26, 2004, one of the world’s most destructive natural disasters occurred. A magnitude Mw 9.1 earthquake (third strongest ever instrumentally recorded) generated a global tsunami that killed about 230,000 people along the coasts of 14 countries in the Indian Ocean and propagated as far as the North Pacific and North Atlantic Oceans. Since then, various countries from around the globe contributed major funding to tsunami research and mitigation, enabling the installation of hundreds of new high-precision instruments, the development of new technology and the establishment of more modern communication systems. As a result, incredible progress has been achieved in tsunami research and operation during the ten years after the 2004 Indian Ocean tsunami. The papers presented in this second of two special volumes of Pure and Applied Geophysics reflect the state of tsunami science during this time, including two papers devoted to global observations. Five papers provide new findings specifically in the Indian Ocean. Eight papers cover Pacific Ocean studies, focusing mainly on the 2011 Tohoku earthquake and tsunami. Remaining papers in the volume describe studies in the Atlantic and Mediterranean and general tsunami source studies. The volume is of interest to scientists and practitioners involved in all aspects of tsunamis from earthquake source processes to transoceanic wave propagation and coastal impacts. Postgraduate students in geophysics, oceanography and coastal engineering – as well as students in the broader geosciences, civil and environmental engineering – will also find the book to be a valuable resource, as it combines recent case studies with advances in tsunami science and natural hazards mitigation.

    Schlagwort(e): Tsunami ; Pacific Ocean
    Beschreibung / Inhaltsverzeichnis: The 2011 Tohoku earthquake generated a catastrophic tsunami that killed nearly 20,000 people along the coast of Japan and caused the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant. The tsunami propagated throughout the Pacific Ocean and also affected many other countries, including Russia, the USA, New Zealand, French Polynesia and Chile, demonstrating once again the terrible threat that tsunami waves pose for Pacific countries and the need for basin-wide international scientific collaboration. Following a brief introduction, this volume presents 21 scientific papers, including 12 on aspects of the 2011 Tohoku event. A first group of papers provides detailed field survey results from the coasts of Japan and Russia and examines the wave dynamics on the basis of these surveys, the source mechanism of the earthquake, and the far-field impacts of the Tohoku tsunami. The second group reports on the 2012 tsunamis in El Salvador, the Philippines, off the east coast of Honshu and the landmark Haida Gwaii event off the west coast of British Columbia, Canada, while the papers in a third set discuss a number of remaining challenging questions in tsunami science and warning. The volume will be of interest to scientists and practitioners involved in all aspects of tsunamis from earthquake source processes to transoceanic wave propagation and coastal impacts. Postgraduate students in geophysics, oceanography and coastal engineering – as well as those in the broader geosciences, civil and environmental engineering – will also find the book a valuable resource, as it combines recent case studies with the latest advances in tsunami science and natural hazards mitigation.

    Schlagwort(e): Tsunami ; Indian Ocean
    Beschreibung / Inhaltsverzeichnis: This is the first volume of a collection of essays focusing on progress in tsunami science since the great tsunami of 26 December. A magnitude Mw 9.1 earthquake (third strongest ever instrumentally recorded) generated a global tsunami that killed about 230,000 people along the coasts of 14 countries in the Indian Ocean and propagated as far as the North Pacific and North Atlantic. Since then, various countries from around the globe contributed major funding to tsunami research and mitigation, enabling the installation of hundreds of new high-precision instruments, the development of new technology and the establishment of more modern communication systems. As a result, incredible progress has been achieved in tsunami research and operation during the ten years after the 2004 Indian Ocean tsunami. The papers presented in this first of two special volumes of Pure and Applied Geophysics reflect the state of tsunami science during this time. Eight papers are related to case studies highlighting regional hazards around the globe, while five papers record progress in tsunami warning systems. Benchmark studies that describe the accuracy of numerical models for tsunami impact, as well as a variety of inundation and generation studies, are presented by 7 additional papers.

    Beschreibung: On September 16, 2015, a Mw 8.3 earthquake struck the north-central Chile coast, triggering a tsunami observed along 500 km of coastline, between Huasco (28.5°S) and San Antonio (33.5°S). This tsunami provided a unique opportunity to examine the nature of tsunami deposits in a semi-arid, siliciclastic environment where stratigraphic and sedimentological records of past tsunamis are difficult to distinguish. To improve our ability to identify such evidence, we targeted one of the few low-energy, organic-rich depositional environments in north-central Chile: Pachingo marsh in Tongoy Bay (30.3°S). We found sedimentary evidence of the 2015 and one previous tsunami as tabular sand sheets. Both deposits are composed of poorly to moderately sorted, gray-brown, fine-to medium-grained sand and are distinct from underlying and overlying organic-rich silt. Both sand beds thin (from ∼20 cm to 〈1 cm) and fine landward, and show normal grading. The older sand bed is thicker and extends over 125 m further inland than the 2015 tsunami deposit. To model the relative size of the tsunamis that deposited each sand bed, we employed tsunami flow inversion. Our results show that the older sand bed was produced by higher flow speeds and depths than those in 2015. Anthropogenic evidence along with 137Cs and 210Pb dating constrains the age of the older tsunami to the last ∼110 years. We suggest that the older sand bed was deposited by the large tsunami in 1922 CE sourced to the north of our study site. This deposit represents the first geologic evidence of a pre-2015 tsunami along the semi-arid north-central Chile coast and highlights the current and continuing tsunami hazard in the region.

    Beschreibung: Since more than 15 years, the Cluster mission passes through Earth's radiation belts at least once every two days for several hours, measuring the electron intensity at energies from 30 to 400 keV. This data has previously been considered not usable due to contamination caused by penetrating energetic particles (protons at 〉100 keV and electrons at 〉400 keV). In this study, we assess the level of distortion of energetic electron spectra from the RAPID/IES detector, determining the efficiency of its shielding. We base our assessment on the analysis of experimental data and a radiation transport code (Geant4). In simulations, we use the incident particle energy distribution of the AE9/AP9 radiation belt models. We identify the Roederer L-values, L⋆, and energy channels that should be used with caution: at 3≤L⋆≤4, all energy channels (40 – 400 keV) are contaminated by protons (≃230 to 630 keV and 〉600 MeV); at L⋆≃1 and 4–6, the energy channels at 95 – 400 keV are contaminated by high energy electrons (〉400 keV). Comparison of the data with electron and proton observations from RBSP/MagEIS indicates that the subtraction of proton fluxes at energies ≃ 230–630 keV from the IES electron data adequately removes the proton contamination. We demonstrate the usefulness of the corrected data for scientific applications.

    Beschreibung: A lasting legacy of the International Polar Year (IPY) 2007–2008 was the promotion of the Permafrost Young Researchers Network (PYRN), initially an IPY outreach and education activity by the International Permafrost Association (IPA). With the momentum of IPY, PYRN developed into a thriving network that still connects young permafrost scientists, engineers, and researchers from other disciplines. This research note summarises (1) PYRN’s development since 2005 and the IPY’s role, (2) the first 2015 PYRN census and survey results, and (3) PYRN’s future plans to improve international and interdisciplinary exchange between young researchers. The review concludes that PYRN is an established network within the polar research community that has continually developed since 2005. PYRN’s successful activities were largely fostered by IPY. With 〉200 of the 1200 registered members active and engaged, PYRN is capitalising on the availability of social media tools and rising to meet environmental challenges while maintaining its role as a successful network honouring the legacy of IPY.
