An alternative plural form of epicenter, used in scientific and technical contexts; the points on Earth's surface directly above earthquake origins.
Latin neuter plural of 'epicentrum.' This form reflects the Latinate conventions sometimes used in scientific writing, though 'epicenters' has become the standard English plural in modern usage.
Scientists sometimes use 'epicentra' in formal research papers to sound more technically precise, but it's become somewhat old-fashioned—a reminder that even in science, word choices reflect historical preference for Latin-sounding terminology.
