“…It has been demonstrated that resonance can have an important role in tsunami wave amplification in some coastal areas, where tsunami behavior can be influenced mostly by the local bathymetry rather than the tsunami characteristics at the source (Power & Tolkova, ; Rabinovich, ; Zaytsev et al, ).. In addition, morphological features such as islands, peninsulas, and submarine canyons influence oscillation modes and contribute to coupled systems (Park et al, ).…”

Tsunami Resonance and Spatial Pattern of Natural Oscillation Modes With Multiple Resonators

et al. 2019

Tsunami resonance and coupled oscillation of shelf and bays modes has been reported to be important in tsunami wave amplification. The main objective of this work is to study the spatial pattern of natural oscillation modes and to analyze the influence of several resonators on the coast of the central Chile, which has a complex morphology with several bays, submarine canyons, and a wide continental shelf. First, natural oscillation modes were computed by means of modal analysis of local and regional domains. Second, a dense network of tide gauges and pressure sensors was analyzed to obtain background spectra inside bays. Third, tsunami spectra were computed from both tsunami records and numerical simulations. The results show that the use of modal analysis and background and tsunami spectra is effective for identifying natural oscillation modes. In addition, a dense network of tide gauges is useful to validate the spatial pattern of these natural modes. It was observed that larger resonators and the shelf are important in coupling oscillation with local bays, such that large amplification can be observed. Finally, this analysis allowed the diverse effects of 2010 and 2011 tsunamis in the bays of central Chile to be explained, making it possible to better address tsunami mitigation measures and the preparedness of coastal communities.

“…Zaytsev et al () recently demonstrated that the mean spectral ratio

\hat{R} (ω)

estimated from coastal tsunami measurements can be used to reconstruct the realistic open‐ocean tsunami spectrum that would be similar to the tsunami spectrum directly evaluated from the DART observations. The main criterion for the effective reconstruction is the consistency of the spectral ratios, i.e., exactly what we see in Figure for the 2004 spectral ratios on and off the coast of Chile.…”

The 2004 Sumatra tsunami was an unprecedented global disaster measured throughout the world oceans. The present study focused on a region of the southeastern Pacific Ocean where the “westward” circumferentially propagating tsunami branch converged with the “eastward” branch, based on data from fortuitously placed Chilean DART 32401 and tide gauges along the coast of South America. By comparison of the tsunami and background spectra, we suppressed the influence of topography and reconstructed coastal “spectral ratios” that were in close agreement with a ratio at DART 32401 and spectral ratios in other oceans. Findings indicate that even remote tsunami records carry spectral source signatures (“birth‐marks”). The 2004 tsunami waves were found to occupy the broad frequency band of 0.25–10 cph with the prominent ratio peak at period of 40 min related to the southern fast‐slip source domain. This rupture “hot‐spot” of ∼350 km was responsible for the global impact of the 2004 tsunami. Data from DART 32401 provided validation of model results: the simulated maximum tsunami wave height of 2.25 cm was a conservative approximation to the measured height of 2.05 cm; the computed tsunami travel time of 25 h 35 min to DART 32401, although 20 min earlier than the actual travel time, provided a favorable result in comparison with 24 h 25 min estimated from classical kinematic theory. The numerical simulations consistently reproduced the wave height changes observed along the coast of South America, including local amplification of tsunami waves at the northern stations of Arica (72 cm) and Callao (67 cm).

“…As a companion paper to Zaytsev et al (2016), who examined recordings from three recent Chilean tsunamis (2010, 2014, and 2015) along the coast of Mexico, Zaytsev et al (2017) investigates the manifestation of the 2011 Tohoku tsunami on this same coast. Statistical and spectral analyses of the onshore and offshore tsunami records allowed the authors to estimate the principal parameters of the waves and to compare statistical features of the 2011 tsunami with other tsunamis recorded along this coast.…”

“…One of the findings of Zaytsev et al (2016Zaytsev et al ( , 2017) was the identification of ''hot spots'' along the coast of Mexico (Manzanillo, Zihuatanejo, Acapulco, and Ensenada) corresponding to sites having greater tsunami wave heights compared to other parts of the coast. For the U.S. West Coast, a well-known ''hot spot'' is Crescent City (California) that typically records the largest wave heights and has suffered more loss than any other North American site in the past century.…”

Abstract-Twenty-two papers on the study of tsunamis are included in Volume II of the PAGEOPH topical issue ''Global Tsunami Science: Past and Future''. Volume I of this topical issue was published as PAGEOPH, vol. 173, No. 12, 2016 (Eds., E. L. Geist, H. M. Fritz, A. B. Rabinovich, and Y. Tanioka). Three papers in Volume II focus on details of the 2011 and 2016 tsunamigenerating earthquakes offshore of Tohoku, Japan. The next six papers describe important case studies and observations of recent and historical events. Four papers related to tsunami hazard assessment are followed by three papers on tsunami hydrodynamics and numerical modelling. Three papers discuss problems of tsunami warning and real-time forecasting. The final set of three papers importantly investigates tsunamis generated by non-seismic sources: volcanic explosions, landslides, and meteorological disturbances. Collectively, this volume highlights contemporary trends in global tsunami research, both fundamental and applied toward hazard assessment and mitigation.
