past earthquakes have highlighted the vulnerability of water systems in seismic regions in the world. Earthquakes have resulted in catastrophic water service interruptions and millions of dollars in damages. Differing seismic mitigations practices are being developed by a wide variety of organizations in the United States, Japan and Taiwan. Each practice attempts to address specific observations from past earthquakes. Seismic mitigation measures can best be improved if these practices are gathered, critically examined and disseminated to the international seismic community. Through this process we can all learn from one another. The AWWARF/JWWA Water Seismic Conference were a series of joint workshops convened by the American Water Works Association Research Foundation (AwwaRF) and the Japan Water Works Association (JWWA). They brought together experts from utilities along with consultants and academicians from the United Sates, Japan and Taiwan to discuss both the differences and similarities of the seismic practices for water systems. Participation was strongly emphasized to focus on practical and useful information generated from experience and research. The workshops further promote the corporation and collaboration among the participating organizations in developing the state-of-the-art technologies of improving earthquake preparedness and response.
