Abstract

The 2011 Tohoku tsunami is one of the instrumentally most well recorded tsunami in the past century. Additionally, rapid global communication of the tsunami’s impending arrival at far-field locations allowed for not only mitigation of hazard, but broad human observation of the incoming wave-train. We seek to combine these unique data sets by analyzing tide gauge records of the 2011 Tohoku tsunami with far-field observations obtained from local media outlets to quantify the effect of tsunami wave height on human perceptibility. Our goal is to provide a bridge between quantitative tsunami model output and qualitative tsunami observation that will help to inform hazard mitigation for tsunami in the far-field. Our results could be combined with future numerical tsunami modeling to provide a sense of a tsunami’s hazard to locations in the far-field or, additionally, these results could be combined with historical reports of far-field tsunami inundation to help provide constraints on tsunami wave amplitude from historical tsunami events.
