“…Probably the first documented account of adopting engineered structural measures in buildings to withstand the forces generated by earthquakes was in Japan in 1895 [93], while earlier seismic design codes date back to 1927 in USA [94] and in early 1930s in Chile [95] and India/Pakistan [96]. Ever since these early efforts, the field of earthquake resistant design has advanced to the use of various forms of traditional seismic lateral force resistance systems such as ductile moment frames, braced frames, and shear walls, as well as the use of base-isolation, supplemental damping devices, and active control of lateral forces induced by an earthquake in a variety of structures ranging from residential houses to skyscrapers to bridges and nuclear power plants [97].…”

Natural hazards are processes that serve as triggers for natural disasters. Natural hazards can be classified into six categories. Geophysical or geological hazards relate to movement in solid earth. Their examples include earthquakes and volcanic activity. Hydrological hazards relate to the movement of water and include floods, landslides, and wave action. Meteorological hazards are storms, extreme temperatures, and fog. Climatological hazards are increasingly related to climate change and include droughts and wildfires. Biological hazards are caused by exposure to living organisms and/or their toxic substances. The COVID-19 virus is an example of a biological hazard. Extraterrestrial hazards are caused by asteroids, meteoroids, and comets as they pass near earth or strike earth. In addition to local damage, they can change earth inter planetary conditions that can affect the Earth’s magnetosphere, ionosphere, and thermosphere. This entry presents an overview of origins, impacts, and management of natural disasters. It describes processes that have potential to cause natural disasters. It outlines a brief history of impacts of natural hazards on the human built environment and the common techniques adopted for natural disaster preparedness. It also lays out challenges in dealing with disasters caused by natural hazards and points to new directions in warding off the adverse impact of such disasters.

“…In reality, this trend does not continue indefinitely and is limited by the maximum magnitude. Another important consideration in recurrence modelling is ascertaining the maximum credible earthquake (MCE) magnitude which is dependent on the size of the potential seismic sources7,28,29,30.…”

“…Analytical models have been developed to model a combination of wave modification mechanisms56–60. Alternatively, simple manual methods, such as the Code response spectrum models, may be used for general seismic hazard analyses1–6,1–62. Such code models have been developed from statistical analyses of large volumes of empirical data63–65.…”

Major intraplate earthquakes are rare, however, their occurrence is often unpredictable and can result in high consequences in terms of both life‐safety and economic loss. Consequently, the issue of intraplate seismic hazard is attracting increasing attention from the world community. It is important that the overall process of modelling earthquake‐induced loads is well understood by structural engineers who are professionally responsible and accountable for the performance of the structure and for life‐safety. The modelling for seismic hazard in regions of low and moderate seismicity is difficult and challenging, owing to the paucity of earthquake data in these regions. The objective of this paper is to present an overview of the seismic hazard analysis procedure for regions of low to moderate seismicity to a wide engineering readership. The review covers topics ranging from the modelling of seismic activity, the attenuation of seismic waves and site amplification to the representation of seismic loading for design purposes. Basic concepts that are widely known within the earthquake engineering profession are introduced for the benefit of readers who do not possess specialized knowledge in this field. Further, the latest techniques that have been developed to overcome the challenges associated with the paucity of data in regions of low to moderate seismicity are described.

“…Their use has been growing over the past few decades thanks to the increasing interest in geotechnical earthquake engineering, and particularly in shear wave velocity (V s ) measurements (e.g. Beavers, 2002;Chaillat et al, 2009;Foti et al, 2015;. This is a consequence of the introduction of a number of anti-seismic building codes (e.g.…”
