seismiliste

Seismiliste is a term used in Estonian grammar and science writing as the genitive plural form of the adjective seismiline, meaning seismic or relating to earthquakes. It appears most often in phrases where the noun it modifies is in the genitive plural, such as seismiliste andmete (of seismic data) or seismiliste lainete (of seismic waves). The base form seismiline denotes anything connected with seismic activity, seismoloogia, or the study of earthquakes.

In practical use, seismiline describes attributes of phenomena or objects studied in seismology and geophysics. For example, seismiliste lainete kiirus refers to the speed of seismic waves, and seismiliste aluste monitoring refers to monitoring of seismic bases or installations. The word is employed across scientific contexts, including data analysis, monitoring networks, and earthquake research, where precise phrasing often requires a noun in genitive plural paired with the genitive plural form of the adjective.

Etymology cases the Estonian seismiline word to originate from the international scientific vocabulary rooted in the Greek word seismos, meaning earthquake, and has been adapted into Estonian as part of the common linguistic family for describing seismic phenomena. The usage mirrors similar constructions in many languages where a root related to earthquake forms a stable adjective block used with a variety of nouns.
