Joso flood citizen's evacuation behavior survey

Last month at a meeting of the working group on flood evacuation and emergency measures, a professor from Chuo University presented results from a survey conducted among citizen's concerning their evacuation behavior and flood preparedness.

These are preliminary results, and as such should not be used as evidence until confirmed.

Over 500 people were questioned. It was found that at the time of the disaster (12:50 pm), about 96% of respondents were at home. 28.6% went to evacuation centers, 29.9% to a different safe place, and 41.5% did not evacuate.

For the question 'what was your reason for evacuating?' (multiple answers allowed), 34% answered they listened to the evacuation information, and 31.7% followed recommendations from family, friends, and governmental officers. 

For people who chose not to evacuate, 46.7% did not expect inundation, 18.9% believed to be safe on the second floor of their house, and 15.1% didn't feel afraid.

50.8% of the people reported having received information about evacuation through loudspeakers, 15.1% through television, 0.4% through the city homepage, and 25.8% reported not having heard information. 

Finally, the city had previously distributed flood hazard maps door to door. However, 61.0% of respondents said never to have seen the flood hazard map before.
