Even though families with disabilities at the time of disasters are more likely to be socially isolated and inconvenienced, there has been almost no detailed investigations on them. Therefore, in this study, we conducted a questionnaire survey of families with intellectual disabilities focusing on the lessons from the 2016 Kumamoto earthquake. As a result, it turned out that many families with intellectual disabilities have sustained difficulties for months based on various factors. Utilizing our findings, we compiled and distributed a pamphlet (“8 wisdoms acquired from the Kumamoto earthquake”) for the people involved.

Two types of learning programs in education for stress management after disasters were developed, implemented at an elementary school, and effectiveness was verified. Participants were fifth and sixth graders (N=229). One of the two programs were conducted in the first session and the other program was conducted in the second session. The first program aimed to understand individual symptoms of stress responses and facilitate classify symptoms into four groups. The second program aimed to select measures to cope with stress and develop the skills needed to execute them. Before and after each session, a questionnaire using the revised version of the scale developed by Toyosawa et al. was administered. The questionnaires were collected and statistically analyzed. The results indicated a significant increase in the feeling of fear between pretest and posttest of Session 1. Especially, children indicating low-middle level fear scores in the pretest showed a large increase in fear scores. After Session 2, self-efficacy and response efficacy significantly increased and severity of threats significantly decreased.

We used rainfall information obtained using a single X-band multi-parameter (UY) radar and C-band radars to estimate the risk of shallow landslides. Although rainfall data derived from the UY radar were underestimated compared with the rain gauge data 20-30 km further from the radar site, the correlation coefficient between two measurement methods was high. According to this comparison, we divided the UY radar data into a moving average within a 2.5 km mesh and ratio of rainfall to the moving average. The moving average was then corrected by the C-band radar information and combined with the ratios. The root mean-square error, mean error, and correlation coefficients significantly improved with the combined rainfall data. The risk of shallow landslides was accurately estimated using the soil water index calculated with a tank model and the combined hourly rainfall data for an area where shallow landslides have occurred.
