epicentre (plural epicentres)

1. (seismology) The point on the land or water surface directly above the focus, or hypocentre, of an earthquake.
   • 2008, Michael Woods, Mary B. Woods, Earthquakes, Lerner Books, →ISBN, page 18:

     The epicentre isn't always the point of heaviest damage. Faults can be many kilometres long and seismic waves shake areas all along the fault.

   Synonym: ground zero

3. (figuratively, proscribed) The focal point of any activity, especially if dangerous or destructive.

   • 2020 February 6, Laurie Chen, “Communist officials fired after disabled Chinese boy died when relatives were put in coronavirus quarantine”, in South China Morning Post‎, →ISSN, →OCLC, archived from the original on 06 February 2020, Society‎:

     Yan Cheng had cerebral palsy and died on January 29 while in the care of officials in Huajiahe township, Hongan county, more than 100 kilometres (62 miles) from Wuhan, the epicentre of the outbreak.

The loose usage “center”, or specifically “center of a disaster”, is criticized by some as pretentious and incorrect,^[2][3][4] since epi- specifically means “over, on top”, and is not a generic intensifier.

A more semantic objection is that epicenter implies a singular center of a disaster, which is misleading for many disasters, such as diseases, which do not spread simply by radiation. Instead, hot spot is preferred by some as less misleading.^[1]

Nevertheless, epicenter is widely used for diseases and other disasters, both in media and epidemiology.
