In order to clarify the movement behavior conditions for pregnant women to evacuate safely when an earthquake occurs, simulated pregnant women under a seismic intensity of lower 6: A walk forward with a long stride, and B walk sideways with a desk as support. was set and asked to walk 5m30cm. As a result, A has a high possibility of falling, but can move faster than B, and B has a low possibility of falling, but moves slowly. It was suggested that it is necessary to select the movement behavior based on the characteristics of the environment under the earthquake.
