During the 2011 East Japan Earthquake and Tsunami, newly popular social media such as Twitter and Facebook served as a lifeline for directly affected individuals, a means of information sharing, and a way for people inside and outside Japan to volunteer and to provide information-based support to affected individuals. Social media was used to perform vital relief functions such as safety identification, displaced-persons locating, damage information provision, support for disabled individuals, volunteer organization, fund-raising, and moral support systems. This study discusses the potential for public, civil society, and government organizations to utilize social media in disaster preparedness and response.

Disaster risk reduction education is provided through external support at schools. Most educational programs evaluate the level of knowledge transfer. However, the particular context of school is not considered, even though it prescribes the understanding of students. In this study, tsunami education was provided by a non-Mexican NGO at two schools in Acapulco, Mexico, and questionnaire surveys were conducted. The surveys identified that students were more interested in obtaining knowledge than learning action for their self-protection. This tendency in motivation was generated by the school context: the school teaches decontextualized knowledge despite the need to contextualize disaster education in daily life. This disparity caused a gap in the communication between the NGO members and the students. Therefore, it is important that disaster education programs remove students from the school context and place them in the context of daily life. More localized content could help remove students from the context of school. This study argues that the effectiveness of disaster education is influenced by the context in which students learn, and the findings suggest that educational practices should be designed on the basis of the context of the learners.

A hazard assessment of a possible future eruption of Mount Fuji was made from data in old documents recording the tephra fall of its 1707 eruption. The thickness of basaltic scoriae and ash in 120 localities as far away as Tokyo was found from historical records. An isopach map was drawn from thes data which is in good agreement with the isopach map made by Tsuya based on his volcano-stratigraphic study. The major axis of the isopachs coincides with the prevailing wind direction during the corresponding months as recorded at the Weather Observatory on the summit of Mount Fuji. Old documents prove that the delay in the tephra fall between Odawara and Tokyo is approximately one hour, enough time for diaster warnings to be given. An eruption of Mount Fuji in the near future is likely after its long period of dormancy and probably will be explosive as was the 1707 eruption. Thus, the volcanic events of the 1707 eruption are considered a good basis from which to make a hazard assessment of Mount Fuji. A hazard map was drawn from the data collected on this 18th century eruption.

The peak horizontal acceleration and velocity of observed records from the 1995 Hyogoken-nambu earthquake are compared with those predicted from empirical attenuation relations that were found applicable to the near-distance area. The observed peak values match well the existing empirical attenuation relations, although unpredictable severe damages occured due to strong ground motions in Kobe and adjacent cities close to the faulting zones. The observed peak vertical accelerations are about half the peak horizontal ones at less than 100 cm/s/s, as in the empirical relations, but they tend to be more than half at more than 100 cm/s/s. This suggests that the horizontal motions were more markedly affected by the horizontal non-linear behavior of the soils in the surface layers during strong horizontal motion than during vertical motions.

This paper is based on the results of research by the Sumatra Earthquake Interdisciplinary or Integrated Research Team, Graduate School of Environmental Studies, Nagoya University. This research shows: (1) the Sumatra Earthquake tsunami disaster damage in Banda Aceh can be divided into four areas; (2) the tsunami action was directed left and right by the Banda Aceh topography; (3) within which District I saw total destruction of housing, a high death rate, and the collapse of families; (4) with the high death rate due to a lack of earthquake-tsunami association; (5) that even in the core of housing reconstruction, the pace is slow; (6) there are four main obstacles to housing reconstruction; (7) the slow pace of the reconstruction is a function of social causes related to the size of the tsunami, the lack of established adjustment mechanisms for aid groups, the slow pace of the reconstruction in society overall, and the failure of market functions; (8) that in the case of large scale disasters, with the loss of life and home, as well as infrastructure, the collapse of society as an entity occurs as well.

This paper reports a research study on disaster reduction education, at both a senior high school and in a local community in Japan. The research was guided mainly by the theory of “community of practice (CoP)” proposed by Lave and Wenger (1991). This theory provided a useful framework by which we achieved long-term and collaborative learning in disaster education, to deal with natural disasters with a long return period. A gaming approach was introduced in this year-long action research project, as a key medium to realize long-term and cogenerative learning by diverse stakeholders, ranging from high school students, local residents, local government workers, and disaster experts. This gaming approach covered the whole process, from co-planning, co-production, and co-dissemination of game-like education materials. The results suggested the clear superiority of cogenerative disaster education (along with a transformation of CoP structure) over conventional, knowledge internalization-oriented disaster education.
