    Description / Table of Contents: 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.

    Keywords: Tsunami ; Indian Ocean
    Description / Table of Contents: 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.

    Keywords: Tsunami ; Pacific Ocean
    Description / Table of Contents: 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.

    Description: Computational methods are reported for construction of discrete and continuum Schroedinger states in atoms and molecules employing explicit Hilbert space procedures familiar from bound state studies. As theoretical development, the Schroedinger problem of interest is described, the Cauchy-Lanczos bases and orthonormal polynomials used in constructing L-squared Stieltjes-Tchebycheff (ST) approximations to the discrete and continuum states are defined, and certain properties of these functions are indicated. Advantages and limitations of the ST approach to spectral studies relative to more conventional calculations are discussed, and aspects of the approach in single-channel approximations to larger molecules are described. Procedures are indicated for construction of photoejection anisotropies and for performing coupled-channel calculations employing the ST formalism. Finally, explicit descriptive intercomparisons are made of the nature and diagnostic value of ST functions with more conventional scattering functions.

    Description: For three decades, magnetospheric field and plasma measurements have been made by diverse instruments flown on spacecraft in many different orbits, widely separated in space and time, and under various solar and magnetospheric conditions. Scientists have used this information to piece together an intricate, yet incomplete view of the magnetosphere. A simultaneous global view, using various light wavelengths and energetic neutral atoms, could reveal exciting new data and help explain complex magnetospheric processes, thus providing us with a clear picture of this region of space. The George C. Marshall Space Flight Center (MSFC) is responsible for defining the IMI mission which will study this region of space. NASA's Space Physics Division of the Office of Space Science placed the IMI third in its queue of Solar Terrestrial Probe missions for launch in the 1990's. A core instrument complement of three images (with the potential addition of one or more mission enhancing instruments) will fly in an elliptical, polar earth orbit with an apogee of 44,600 km and a perigee of 4,800 km. This paper will address the mission objectives, spacecraft design consideration, interim results of the MSFC concept definition study, and future plans.

    Description: We report the result of a 2010 survey of the effects on the Iranian coastline of the tsunami which followed the earthquake of 27 November 1945 ( M 0 = 2.8 × 1028 dyn cm; M w = 8.2), the only large event recorded along the Makran subduction zone since the onset of instrumental seismology. Based on the interview of elderly survivors of the event, we obtained a database of nine values of run-up or splash amplitudes on a segment of shore extending 280 km from Souraf in the West to Pasabandar near the Pakistani border, and ranging in vertical amplitude from 2.3 to 13.7 m. Witness reports are consistent with a significant delay (estimated at ~2.5 h) of the tsunami waves, suggesting that they were generated by an ancillary phenomenon, such as a landslide triggered by the earthquake. None of our witnesses bore ancestral memory of comparable events in the past, suggesting that reported predecessors to the 1945 earthquake may have been smaller in size. The survey also allowed the compilation of previously unreported data concerning the effects of the 2004 Sumatra–Andaman tsunami. ©2015 Springer Basel

    Description: Watermarks found during the post-event surveys of the 2011 Tohoku tsunami confirmed extreme runup heights at several locations along the central to northern part of the Sanriku coast, Japan. We measured the maximum height of nearly 40 m above mean sea level at a narrow coastal valley of the Aneyoshi district. Wave records by offshore GPS-buoys suggest that the remarkably high runup was associated with a leading, impulsive crest of the tsunami amplified by local bathymetry and topography. In order to elucidate the underlying amplification mechanism, we apply a numerical model to reproduce the measured distribution of tsunami heights along the target coastline. A series of numerical tests under different boundary conditions suggests that a spectral component with a dominant period of 4–5 min in the leading wave play a key role in generating the extreme runup. Further analyses focusing on the Aneyoshi district confirm that the short wavelength component undergoes critical amplification in a narrow inlet. Our findings highlight the importance of resolving offshore waveforms as well as local bathymetry and topography when simulating extreme runup events. ©2014 Springer Basel

    Description: On 27 August 2012 (04:37 UTC, 26 August 10:37 p.m. local time) a magnitude M w = 7.3 earthquake occurred off the coast of El Salvador and generated surprisingly large local tsunami. Following the event, local and international tsunami teams surveyed the tsunami effects in El Salvador and northern Nicaragua. The tsunami reached a maximum height of ~6 m with inundation of up to 340 m inland along a 25 km section of coastline in eastern El Salvador. Less severe inundation was reported in northern Nicaragua. In the far-field, the tsunami was recorded by a DART buoy and tide gauges in several locations of the eastern Pacific Ocean but did not cause any damage. The field measurements and recordings are compared to numerical modeling results using initial conditions of tsunami generation based on finite-fault earthquake and tsunami inversions and a uniform slip model. ©2014 Springer Basel
