Primary effects: which are the surface expression of the seismogenic source (e.g., surface faulting), normally observed for crustal earthquakes above a given magnitude threshold (typically M w =5.5–6.0); Coseismic liquefaction induced by one of the 2012 Emilia, Northern Italy, earthquakes
The public tends to feel more negatively towards earthquakes caused by human activities than natural earthquakes. [96] Two major parts of public concern are related to the damages to infrastructure and the well-being of humans.

Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
Earthquakes are not only categorized by their magnitude but also by the place where they occur. The world is divided into 754 Flinn–Engdahl regions (F-E regions), which are based on political and geographical boundaries as well as seismic activity. More active zones are divided into smaller F-E regions whereas less active zones belong to ...
