This report presents findings of earthquake damage to lifeline facilities. Topics included are dams, water supply, sewage, power, communications, liquid fuels, and general transportation. Port facility structural and geotechnical aspects of the earthquake are discussed in Chapter 5—Industrial Facilities. Performance of bridges is discussed in Chapter 6—Bridges.

Water management systems in industrial facilities, industrial zones, hospitals and other internal water systems relatively frequently fail to meet the intended purpose for which they were built when an extraordinary event occurs. They may even pose a safety hazard. The causes of this condition may be of internal or external origin. Given that internal water supply systems of large premises always have a multipurpose character, i.e. to provide enough drinking water for drinking and sanitation purposes and also as a source of fire water for the fire safety of buildings, they must meet a wide range of hydraulic conditions and technical-operational capabilities. By what means and methods it is possible to achieve the desired state in economically-acceptable dimensions, while maintaining all the necessary hydraulic capabilities of the supply points of drinking and fire water, is briefly described in this article.

This paper reviews the situations and features of earthquake damage to industrial facilities, manufacturing companies, energy supply facilities, and mechanical structures and installations in Japan, and traces trends of countermeasure technology developed focusing on earthquake resistance and vibration control. In Japan, with the 1964 Niigata earthquake as the turning point, earthquake damage to industrial facilities became a social problem. With power stations being constructed in the 1960s, it also became an important technological policy to establish seismic design method for nonbuilding structures such as equipment and piping systems related to nuclear power. The Kobe earthquake in 1995 damaged production companies including leading manufacturers so extensively that it brought a new focus to seismic considerations. We studied the damage to typical equipment and installations and, based on this experience, investigated the features of damage modes to industrial facilities and machinery and considered corresponding technical measures. We present some examples and discuss progressive trends in seismic and vibration control technology following the Kobe earthquake. In particular, we focus on the new seismic design code for high-pressure gas facilities and the development of seismic and vibration control dampers and their applications.

The article contains the results of the systematic scientific-research and research-development work, which ensured the implementation of innovating power efficient and ecological technologies, aimed at the increase of reliability and economic efficiency of heat supply to industrial facilities and populated areas in the regions, experiencing deficiency of traditional power-generating fuel. The article presents the solution of relevant scientific problems, results of the researches, on the basis of which the new structures of combined low emission burner device with staged burning of gaseous and liquid fuels and fire-tube boilers with increased efficiency (not less than 94 %) are suggested. The results of experimental researches on factory test benches and operation facilities in operating load range from 40 to 100 % of nominal load, confirmed the boiler efficiency of more than 94 % – this is by 4–6 % higher than existing indicators in case of burning raw oil and fuel oil and by 2–4 % higher than in case of burning natural gas. The protection of boiler from low temperature sulphur corrosion is provided by the compact remote economizer. The developed equipment reduces emissions of nitrogen oxide into the atmosphere by 25–30 % in comparison with the regulatory levels and by 10–15 % in comparison with the best foreign analogues. Boilers and burners are supplied to the facilities in finished form as a part of compact modular boilers, which significantly reduces commission deadlines.

As buildings become more resilient against structural damage the cost of non-structural damage and their consequences becomes proportionally higher, giving non-structural damage greater importance in earthquake risk reduction. Providing residents with detailed guidance on how to evaluate their risk regarding non-structural earthquake damage, and what mitigation and preparedness options they have, can increase both home and societal earthquake resiliency. Earthquake damage data from destructive earthquakes in south Iceland in 2000 and 2008 were used to develop simple but detailed twelve-step risk-management guidelines for residents. The guidelines are based on a set of disaster-related objectives. A standard loss estimation study was used to develop guidelines for the fixed non-structural elements and photographs from inside homes that had sustained significant non-structural damage were used to develop guidelines for loose items. Virtually every item in the studied homes was considered to understand its importance and its relevance to the function of a home. Information in terms of financial, functional and emotional value were used in the guidelines to help residents decide which mitigation options to take. The photos provided valuable information by placing each item in context with its surroundings, for example, to understand the possibility of motion and consequences to other items. The proposed approach, although based on observations from residential buildings, is useful for facilities that have sensitive operations, such as offices, industrial facilities, hospitals and government services. As societies become more complex and reliant on non-structural elements, systematic and thorough studies such as the one outlined herein become an increasingly critical part of sound earthquake risk management.
