“…Future work on this area can focus on a more comprehensive integration of these systems with other critical systems, such as emergency response organizations, medical care systems (e.g., acute care hospitals) and highway transportation systems from the viewpoint of community resilience. Similar efforts are underway within many utilities around the world like the Water Seismic Study from the Portland Water Bureau's as part of the Oregon Resilience Plan (ORP) (Saling and Stuhr, 2017); performance and management of the gas, electric, water, wastewater and road networks in Christchurch, New Zealand to rapidly reinstate the functionality of critical infrastructure systems (Giovinazzi et al, 2011); Tokyo Metropolitan Reslience Project (Furuya et al, 2019) and the San Francisco Public Utilities Commission's (SFPUC) $4.6B Water System Improvement Program (WSIP) (Ortiz et al, 2012); among others.…”

Water is often referred to as our most precious resource, and for a good reasondrinking water and wastewater services sustain core functions of the critical infrastructure, communities, and human life itself. Our water systems are threatened by aging infrastructure, floods, drought, storms, earthquakes, sea level rise, population growth, cyber-security breaches, and pollution, often in combination. Marginalized communities inevitably feel the worst impacts, and our response continues to be hampered by fragmented and antiquated governance and management practices. This paper focuses on the resilience of water sector (drinking water, wastewater, and stormwater [DWS]) to three major hazards (Sea-Level Rise, Earthquake, and Cyberattack). The purpose of this paper is to provide information useful for creating and maintaining resilient water system services. The term resilience describes the ability to adapt to changing conditions and to withstand and recover from disruptions. The resilience of DWS systems is of utmost importance to modern societies that are highly dependent on continued access to these water sector services. This review covers the terminology on water sector resilience and the assessment of a broad landscape of threats mapped with the proposed framework. A more detailed discussion on two areas of resilience is given: Physical Resilience, which is currently a major factor influencing disruptions and failures in DWS systems, and Digital Resilience, which is a rapidly increasing concern for modern infrastructure systems. The resilience of DWS systems should be considered holistically, inclusive of social, digital, and physical systems. The framework integrates various perspectives on water system threats by showcasing interactions between the parts of the DWS systems and their environment. While the challenges of change, shock and stresses are inevitable, embracing a social-ecological-technical system-of-systems and whole-life approach will allow us to better understand and operationalize resilience. Impact statementServices provided by water lifeline infrastructure (e.g., drinking water, wastewater, and stormwater [DWS] systems) are critical to modern societies. However, stresses from aging and external threats (e.g., sea level rise, floods, earthquakes) on existing DWS systems and the current practice of siloed governance and management of DWS systems have worsened the vulnerabilities in many communities, especially in the marginalized ones. This paper presents a new framework on managing the resilience of DWS systems in the water sector to three major hazards (Sea-Level Rise, Earthquake, and Cyberattack). The new framework embraces a social-ecological-technical system-of-systems approach and a whole-life approach to allow communities to better understand and operationalize short-term to long-term resilience in their DWS systems. The framework also endorses the integration of the goals of sustainability and resilience for overcoming global water challenges, and provides insights via case studies on how...

To accurately capture ground motion in the Tokyo metropolitan area, we have developed a multi-data integration system that combines a large amount of ground motion data gathered from nationwide strong-motion seismograph networks (K-NET and KiK-net); Metropolitan Seismic Observation network (MeSO-net), which covers the Tokyo metropolitan area with a high density of about 300 observation stations; observation equipment held by private companies; and smartphone-based seismographs. K-NET, KiK-net, and MeSO-net are operated by National Research Institute for Earth Science and Disaster Resilience. The seismic waveform data recorded by MeSO-net, which are based on borehole observations, are one of the most important data sets for this system. To ensure collection of the waveform data, we strengthened the data center functions and made the collected data available to the public. In addition, to estimate the ground motion at the surface, which is important for disaster prevention, from the waveform data of MeSO-net, we carried out temporary seismic and microtremor array observations on the ground surface at each MeSO-net borehole station, and estimated ground amplification characteristics and the S-wave velocity structure. We also developed a smartphone-based seismograph with the aim of realizing seismic observations for tens of thousands of sites in the future. We recruited monitors to deploy the smartphone seismometers in the Tokyo metropolitan area, and developed a function to notify monitors of the results of a rough evaluation of the soundness of buildings based on observation data acquired during an earthquake. Furthermore, we have developed a Tokyo metropolitan area version of Kyoshin Monitor, the strong motion monitor system, with which the current ground motion in the Tokyo metropolitan area can be captured in real time by integrating and visualizing observation data from K-NET, KiK-net, and MeSO-net on a map on the website. We can capture the propagation of the ground motion in detail directly from the high-density data set integrated from these three networks. In addition, we also integrated data from Super-Dense Real-time Monitoring of Earthquakes (SUPREME) network of Tokyo Gas Co., Ltd., which operates about 4,000 observation stations in the Tokyo metropolitan area, after applying a time correction. We verified the integration method by reproducing the ground motion in the Tokyo metropolitan area during the 2011 Tohoku earthquake. The study findings have made it clear that the ground motion in the Tokyo metropolitan area can be captured in more detail by the integration of data produced by the public and private sectors.
