Abstract
We applied a real-time tsunami inundation forecast system to a disaster response plan. We developed a standard operating procedure (SOP) for a tsunami disaster response based on a Plan, Do, Check, Action cycle to effectively use tsunami observation and prediction information provided by a real-time tsunami inundation forecast system during an initial response to a tsunami disaster. In the Plan stage, we ran a workshop on the tsunami disaster response to confirm the current tsunami disaster response plan and develop a timeline plan for a tsunami disaster. In the Do stage, we conducted a tabletop exercise (TTX) for a tsunami disaster using a real-time tsunami prediction system. In the Check stage, we ran a workshop on an after-action review of the TTX. In the Action stage, we applied the SOPs of the real-time tsunami prediction system to the tsunami disaster management plan and conducted a second TTX. As a result, we verified the information provided by a real-time tsunami prediction system to apply the system to a tsunami disaster management plan for real municipalities. It was confirmed that the SOP that we developed allows a real-time tsunami inundation forecast system to enable government staff to safely and effectively respond during a disaster.

Many casualties and severe damage in East Japan occurred due to a tsunami caused by theGreat East Japan Earthquake on 11 March 2011
The result is that local government staff need to modify the current disaster management plan based on the standard operating procedure (SOP) that we developed in the check stage (Figure 11)
Summary
Many casualties and severe damage in East Japan occurred due to a tsunami caused by the. The local government staff in charge of disaster prevention could not gather disaster information for the tsunami inundation area, road damage, lifeline damage, and rescue signals. Based on the lessons learned in the Great East Japan Earthquake, the government and the local governments increased the forecasting scale of the tsunami, formulated an evacuation plan, and established rules for rescue activity times in the forecasted tsunami inundation area. When a major earthquake and tsunami occur in Japan, the local government staff in charge of disaster prevention respond to the disaster by following their local disaster management plan [4]. As an after-action review (AAR), the staff discuss issues from the first TTX and develop the SOP for the initial tsunami disaster response in the Check stage. We conducted a second TTX, and the SOP was verified in the Action stage
