Natural disasters and their mitigation are global issues, especially in Asian countries, which have suffered from such geohazards as earthquakes, tsunamis, and volcanic eruptions and such hydrometeorological hazards as typhoons, cyclones, storm surges, and floods.
Research on natural hazards and disasters is multidisciplinary. Scientists from a wide variety of disciplines study hazards, their causes, their mechanisms, and prediction. Engineers study infrastructures and measures to reduce vulnerability. Social and humanitarian scientists study cultural and societal aspects of disasters. Educators study effective ways to raise people’s awareness and action. In addition to such research activities, practitioners work to implement the results of scientific research into practical policymaking.
This special issue of JDR contains 12 papers on multidisciplinary studies concerning geohazards in Indonesia taken from a Science and Technology Research Partnership for Sustainable Development (SATREPS) project supported by the Japan Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA). SATREPS projects focus on both the scientific aspect, namely, acquiring new knowledge, and the Official Development Aids (ODA) aspect, namely, implementing such knowledge in societal applications.
Following the first review article, which is a project overview, the next four papers report findings on natural hazards – the slip rate on the Lembang fault in Java, tsunami simulation for Java’s Palabuhanratu, the Sinabung volcano eruption in Sumatra, and methods of predicting and evaluating eruptions. One paper reports engineering studies on tsunami disaster mitigation in Padang city and two social science papers present hazards in the contexts of communities and human mobility. Two papers on disaster education cover disaster education development since the 2004 Indian Ocean tsunami and the use of tsunami simulation in disaster education. The last research paper and review article deal with policymaking related to the 2010 Mentawai and 2011 Japan tsunamis, respectively.
All of these papers, including the review articles, have been peer-reviewed by two nonproject reviewers. We thank the authors for their timely contributions and revisions, and the reviewers for their invaluable and wide-ranging comments.
