The 10th Asia-Oceania Symposium on Fire Science and Technology (10th AOSFST) is to be held on October 5-7, 2015 in Tsukuba, Japan. The first AOSFST was held in 1992 by the Asia-Oceania Association for Fire Science and Technology (AOAFST), which was established under the umbrella of the International Association for Fire Safety Science (IAFSS). The AOSFST has been held periodically about 3 year interval at the midterm of the IAFSS international symposia. The two most recent Asia-Oceania symposia were held successfully in Melbourne, Australia and Hefei, China in 2010 and 2012, respectively. The 10th AOSFST will include presentations of peer-reviewed papers, key-note lectures by fire researchers invited from the world and poster sessions for a variety of topics and some exciting events. Asia-Oceania region is among the areas where fire science and technology are developing most rapidly. We heartily invite your participation, not only from Asia-Oceania region but also from regions in the world.
