An immediate evacuation is essential for safety when a big earthquake and a tsunami occurred. For example, Great East Japan Earthquake in 2011 killed over 10 thousand people and over 90 percent of them drowned by the tsunami, that is, people who failed to escape from the tsunami after the earthquake occurred got losses by it. If they evacuated immediately after an earthquake, it would be possible that the losses could be limited. In this study, we analysis text-based information expression on a mobile device to induce immediate evacuation. We implemented an application which provides disaster information on a smartphone, and compare text expression about information of tsunami height, arrival time of tsunami, an expected number of evacuees, damage of buildings and so on. The results of the comparison verification show the sentence based on damage of building using fear-arousing communication is the most effective to induce evacuation in this study. However, in over seventies, the effectiveness of the sentence is less than half.
