“…A dramatic change of the public risk perception towards nuclear energy has happened in the aftermath of the 2011 Tohoku earthquake due to the Fukushima Nuclear Power Plant (NPP) disaster. Further details of the 2011 Tohoku earthquake can be found in Bhattacharya et al (2011) and Goda et al (2013). In this context, it is noteworthy that India and China, which are situated in seismically active regions, are constructing Nuclear Power Plants to meet the increasing high energy demand.…”

One of the challenges faced by the engineering profession is to meet the energy requirement of an increasingly prosperous world. Nuclear power was considered as a reliable option until the Fukushima Daiichi Nuclear Power Plant (NPP) disaster which eroded the public confidence. This short paper shows that offshore wind turbines (due to its shape and form, i.e. heavy rotating mass resting at the top of a tall tower) have long natural vibration periods (>3.0 s) and are less susceptible to earthquake dynamics. The performance of near-shore wind turbines structures during the 2011 Tohoku earthquake is reviewed. It has been observed that they performed well. As NPPs are often sited close to the sea, it is proposed that a small wind farm capable of supplying emergency backup power along with a NPP can be a better safety system (robust and resilient system) in avoiding cascading failures and catastrophic consequences

“…The 11 March 2011 Tohoku (Japan) earthquake has reinforced the idea that strong effects due to local asperities, cause significant variability of ground motion parameters at short rupture distances and similar site conditions [13]. For these reasons, ground motion simulations were carried out with the source parameters used in earlier studies for the 1980 Azores earthquake [9], but isolating the previous adopted asperities for each new case slip distribution considered in this study (Fig.…”

“…Recent major earthquakes, such as the 2004 Sumatra, Indonesia earthquake (Murata et al 2010) and the 2011 Tohoku, Japan earthquake Goda et al 2013), have shown that both primary and secondary hazards result in catastrophic consequences. Damage and loss caused by secondary hazards occasionally exceed those by primary hazards (Daniell et al 2011), and thus all relevant hazards should be incorporated in earthquake disaster management.…”

This study conducts coupled simulation of strong motion and tsunami using stochastically generated earthquake source models. It is focused upon the 2011 Tohoku, Japan earthquake. The ground motion time-histories are simulated using the multiple-event stochastic finite-fault method, which takes into account multiple local rupture processes in strong motion generation areas. For tsunami simulation, multiple realizations of wave profiles are generated by evaluating nonlinear shallow water equations with run-up. Key objectives of this research are: (i) to investigate the sensitivity of strong motion and tsunami hazard parameters to asperities and strong motion generation areas, and (ii) to quantify the spatial variability and dependency of strong motion and tsunami predictions due to common earthquake sources. The investigations provide valuable insights in understanding the temporal and spatial impact of cascading earthquake hazards. Importantly, the study also develops an integrated strong motion and tsunami simulator, which is capable of capturing earthquake source uncertainty. Such an advanced numerical tool is necessary for assessing the performance of buildings and infrastructure that are subjected to cascading earthquake-tsunami hazards.
