Earthquakes are not the only events that cause damage to buildings and infrastructure: earthquake-induced phenomena can as well, for example through soil liquefaction, landslides and tsunamis triggered by undersea landslides. Severe earthquakes also often lead to other effects such as fires (e.g. due to leaks in gas pipes) or supply interruptions (e.g. broken water pipes or electric cables).
Such indirect effects of earthquakes pose a further danger to the public when there are strong earthquakes and often cause a significant proportion of the overall damage.
