Eipealár

Is éard is eipealár ann ná an pointe ar dhromchla an Domhan atá díreach os cionn an fho-láir nó fhócais, an pointe as a eascraíonn crith talún nó pléascadh faoi thalamh. Tagann an focal ón ainmfhocal Nua-Laidineach epicentrum,^[1] laidiniú na haidiachta Gréigise'ἐπίκεντρος' (epikentros), "faoin lárphointe",^[2] ó ἐπί (epi) "ar an, ar, ag"^[3] agus κέντρον (kentron) "lárphointe".^[4] Chum an seismeolaí Éireannach Robert Mallet an focal 'epicenter'.^[5] Is minic a bhaintear mí-úsáid as, áfach, chun an bhrí 'lár' a bhaint as.^[6]
