Introduction to the symposium on “Multiple approaches to reducing and mitigating disaster from Quaternary studies”

Here we briefly introduce 13 papers that exem-plify the role of Quaternary research in disaster prevention and mitigation from multiple approaches ; this is a compilation from the open symposium “Multiple approach to reduce and mitigate disaster from Quaternary studies” held at Fukuoka University on August 27, 2017. These studies cover a variety of topics, from recent natural disasters, to historical and paleo- disasters that were revealed from historical records, and geo-morphological, stratigraphical, and archaeological investigations, in which we demonstrate the significant contributions from Quaternary research to improving hazard assessment.
