Compound disaster due to earthquake and tsunami may cause collapse of coastal dike and then serious human damages like 2011 Great East Japan Earthquake. The present study aims to clarify the fundamental resistance of reinforced coastal dike with concrete panels against earthquake and tsunami overflow. For this, we used a new experimental channel for the compound disaster due to earthquake and tsunami. The experimental results indicated that the gaps between panels on the back slope of the dike were generated due to the earthquake. This part became the trigger for dike breach due to tsunami overflow, showing that the compound disaster may depress the resistance of armored dike against tsunami overflow.
