The 2011 Tohoku event showed the massive destruction potential of tsunamis. The Euro-Japan "Risk assessment and design of prevention structures for enhanced tsunami disaster resilience (RAPSODI)" project aimed at using data from the event to evaluate tsunami mitigation strategies and to validate a framework for a quantitative tsunami mortality risk analysis. Coastal structures and mitigation strategies against tsunamis in Europe and Japan are compared. Failure mechanisms of coastal protection structures exposed to tsunamis are discussed based on field data. Knowledge gaps on failure modes of different structures under different tsunami loading conditions are identified. Results of the wave-flume laboratory experiments on rubble mound breakwaters are used to assess their resilience against tsunami impact. For the risk analysis, high-resolution digital elevation data are applied for the inundation modeling. The hazard is represented by the maximum flow depth, the exposure is described by the location of the population, and the mortality is a function of flow depth and building vulnerability. A thorough search for appropriate data on the 2011 Tohoku tsunami was performed. The results of the 2011 Tohoku tsunami mortality hindcast for the city of Ishinomaki substantiate that the tsunami mortality risk model can help to identify high-mortality risk areas and the main risk drivers.

Lessons Learned from the 2011 Great East Japan Tsunami: Performance of Tsunami Countermeasures, Coastal Buildings, and Tsunami Evacuation in Japan Suppasri, Anawat; Shuto, Nobuo; Imamura, Fumihiko; Koshimura, Shunichi; Mas, Erick; Yalçıner, Ahmet Cevdet (2013-06-01) In 2011, Japan was hit by a tsunami that was generated by the greatest earthquake in its history. The first tsunami warning was announced 3 min after the earthquake, as is normal, but failed to estimate the actual tsunami height. Most of the structural countermeasures were not designed for the huge tsunami that was generated by the magnitude M = 9.0 earthquake; as a result, many were destroyed and did not stop the tsunami. These structures included breakwaters, seawalls, water gates, and control forests. In...
Tsunamis bridging science engineering and society Kanoğlu, Utku; Bernard, Eddıe; Synolakıs, Costas (null; 2015-06-22) There have been significant advances in tsunami science since the devastating 2004 Boxing Day tsunami. Yet, the 2011 Japan tsunami dramatically demonstrated that tsunamis continue to avoidably take lives and cause significant damage. Broadcasted live to a stunned world audience, the trail of destruction in 2011 in probably most tsunami ready nation underscores the difficulties of implementing practical advances in hazard mitigation.

Global propagation of air pressure waves and consequent ocean waves due to the January 2022 Hunga Tonga-Hunga Ha'apai eruption Dogan, Gozde Guney; Yalçıner, Ahmet Cevdet; Annunziato, Alessandro; Yalçıner, Bora; Necmioglu, Ocal (2023-01-01) On January 15, 2022, the Hunga Tonga-Hunga Ha'apai volcano's huge eruption generated tsunami waves globally due to an unusual source in this unique event: fast-traveling air pressure disturbances originated from the explosion of the volcano. Here we investigate the global propagation of the pressure waves (first cycle) and the consequent ocean waves. The analysis of the measured air pressure waves shows that the speed of air pressure linearly increases with time. The peak and trough amplitudes of the pressu...
Tsunami forecast modeling for Turkish coastlines Sharghivand, Naeimeh; Kanoğlu, Utku; Department of Engineering Sciences (2014) Turkish coastlines have been exposed to devastating tsunamis in the past. Today, Turkey has densely populated shorelines with substantial touristic activities and critical infrastructures along its shorelines. Tsunami propagation database and tsunami forecast models for the coastal communities are the two major components of the tsunami forecasting methodology which is developed by the United States National Oceanic and Atmospheric Administration Center for Tsunami Research (NCTR) at the Pacifi c Marine Env...
Historical tsunami in the Makran Subduction Zone off the southern coasts of Iran and Pakistan and results of numerical modeling Heidarzadeh, Mohammad; Pirooz, Moharram D.; Zaker, Nasser H.; Yalçıner, Ahmet Cevdet; Mokhtari, Mohammad; Esmaeily, Asad (2008-06-01) Tsunami hazard in the Makran Subduction Zone (MSZ), off the southern coasts of Iran and Pakistan, was studied by numerical modeling of historical tsunami in this region. Although the MSZ triggered the second deadliest tsunami in the Indian Ocean, among those known, the tsunami hazard in this region has yet to be analyzed in detail. This paper reports the results of a risk analysis using five scenario events based on the historic records, and identifies a seismic gap area in western Makran off the southern c...
