    Description / Table of Contents: The tragedy of the 2004 Indian Ocean tsunami has led to a rapid expansion in science directed at understanding tsunami and mitigating their hazard. A remarkable cross-section of this research was presented in the session: Tsunami Generation and Hazard, at the International Union of Geodesy and Geophysics XXIV General Assembly in Perugia, held in July of 2007. Over one hundred presentations were made at this session, spanning topics ranging from paleotsunami research, to nonlinear shallow-water theory, to tsunami hazard and risk assessment. A selection of this work, along with other contributions from leading tsunami scientists, is published in detail in the 28 papers of this special issue of Pure and Applied Geophysics: Tsunami Science Four Years After the Indian Ocean Tsunami. While Part I focused on modelling and hazard assessment, Part II of this issue includes 14 papers covering new developments in observation and data analysis. These include new analyses of both recent and historical tsunami events, as well as state-of-the-art techniques for tsunami data analysis.

    Notes: [Auszug] The great Sumatra–Andaman earthquake and Indian Ocean tsunami of 2004 came as a surprise to most of the earth science community. Although it is now widely recognized that the risk of another giant earthquake is high off central Sumatra, just east of the 2004 earthquake, there seems to ...

    Notes: The first stage of a method for calculating long-period body wave seismograms in a laterally heterogeneous Earth is presented. First, the elastodynamic equation of motion in spherical coordinates, which is valid for weak lateral heterogeneity, is established using a generalized spherical harmonic expansion of the displacement and traction fields and the elastic parameters. It is shown that the equations for the displacement-traction components can be simplified by using high-wavenumber asymptotic approximations to the first-order coefficients, which are appropriate for 5s - 20s body waves in the mid- to upper mantle. The Born approximation is then used to develop a computationally efficient method for calculating me first-order scattered field in terms of the high-frequency asymptotic solution for a laterally homogeneous Earth. This efficiency is increased further by decomposing the wavefield into its P, SV, and SH components. Finally, the numerical integration of the displacement-traction components is performed for a few selected frequencies and a restricted band of angular degrees, in order to test the validity of the Born approximation. Comparison of these results with those calculated using the Born approximation indicates that the latter is well suited to models of weak lateral heterogeneity in the Earth, for which the elastic parameters can be expressed as a sum of low-order spherical harmonics. It is demonstrated that, for this particular class of models, the Born approximation yields a good representation of the scattered field for frequencies within the long-period body wave band of 0.05–0.2 Hz.

    Description: We have previously developed a tsunami source inversion method based on “Time Reverse Imaging” and demonstrated that it is computationally very efficient and has the ability to reproduce the tsunami source model with good accuracy using tsunami data of the 2011 Tohoku earthquake tsunami. In this paper, we implemented this approach in the 2009 Samoa earthquake tsunami triggered by a doublet earthquake consisting of both normal and thrust faulting. Our result showed that the method is quite capable of recovering the source model associated with normal and thrust faulting. We found that the inversion result is highly sensitive to some stations that must be removed from the inversion. We applied an adjoint sensitivity method to find the optimal set of stations in order to estimate a realistic source model. We found that the inversion result is improved significantly once the optimal set of stations is used. In addition, from the reconstructed source model we estimated the slip distribution of the fault from which we successfully determined the dipping orientation of the fault plane for the normal fault earthquake. Our result suggests that the fault plane dip toward the northeast. ©2017. American Geophysical Union. All Rights Reserved.

    Description: Indonesia is one of the most seismically active countries in the world, and its large, vulnerable population makes reliable seismic hazard assessment an urgent priority. In 2016, the Indonesian Ministry of Public Works and Housing established a team of earthquake scientists and engineers tasked with improving the input data available for revising the national seismic hazard map. They compiled results of recent active fault studies using geological, geophysical, and geodetic observations, as well as a new comprehensive earthquake catalog including hypocenters relocated in a three-dimensional velocity model. Seismic hazard analysis was undertaken using recently developed ground motion prediction equations (GMPEs), and logic trees for the inclusion of epistemic uncertainty associated with different choices for GMPEs and earthquake recurrence models. The new seismic hazard maps establish the importance of active faults and intraslab seismicity, as well as the subduction megathrust, in determining the level of seismic hazard, especially in onshore, populated areas. The new Indonesian hazard maps will be used to update national standards for design of earthquake-resilient buildings and infrastructure.
