Abstract

We cover surveys and planning covering the process from the review process for evacuation behavior to the formulation of disaster management plans after the 2011 Great East Japan Earthquake. We focus on the community disaster management plan for the Ando district of Otsuchi town in Iwate Prefecture. We also examine processes and methods for transforming review results into documentation planning. Based on findings from a survey on evacuation behavior, we evaluate factors influencing evacuation behavior and analyze findings from a “Survey on the Situation of Death in the Ando District.” Based on results, we discuss workshops held on review meetings on disaster management planning for the Ando district neighborhood association. We close by extracting and summarizing the features and problems of Ando district tsunami disaster management.

  12. [12]  All these results were calculated excluding “no answer.”
  13. [13]  Regarding with response rate (rough estimation), because the number of person in each household could not be unidentified, it was conveniently estimated here as follows. First, the number of answered households was calculated as 185, dividing the number of response 296 by average value of household’s person 1.6 which was estimated using answer sheets that the number of persons could be identified. Then dividing the number of answered households (185 households) by the number of distributing households 254 gave 73% of response rate.
  14. [14]  Relative ratio means a ratio calculated among the number of answered persons, not the number of answers, to calculate specific weight for each choice in a questionnaire survey allowing multiple answers.

  18. [18]  Reliability of the data in this survey cannot necessarily be guaranteed because the information obtained in this survey contains many secondary information such as eyewitnesses, guesses, rumors by objective persons themselves, their families, residents of the region etc. Here, taking this limit into consideration, we tried extracting the knowledge of victims’ behavior.

  20. [20]  “Request for Seven Items” is the 7 subjects to promote disaster prevention in Ando District that the review meeting requested as themes to discuss with government of the town, which are 1) building community facilities; 2) developing evacuation places/loads; 3) developing information communication systems; 4) measures for supporting those who require care in disaster; 5) preparing/managing shelters for evacuation; 6) medical care/sanitation; 7) disaster education/out-reach activities.
  21. [21]  According to the survey result (bf Fig. 7), 23% of the answer was “provision of support as much as possible,” many of them were answered by members of neighborhood association and volunteer fire brigades/women firefighting volunteers. In the review meeting, there was an opposition of the opinion over the words of “guide evacuation” mentioned in the disaster prevention handbook. By adjustment of facilitator, the expression was changed to “accompany for evacuation”.
  22. [22]  A volunteer fire brigade adopts a “15 minutes rule” as time to stop rescuing/supporting others after an earthquake and start evacuation of themselves. This “15 minutes” corresponded to the “15 minutes” found at “evaluation of staring time for evacuation” in bf Table 4, hence the time should be close to the real feeling of evacuators in this time.
  23. [23]  The conventional teaching in tsunami disaster prevention that once a tsunami has coming, each one mustn’t care anything, even its parents, and should escape to higher place.
