Etymology

Origin of seismologist

First recorded in 1855–60; seismolog(y) ( def. ) + -ist ( def. )

Explanation

A scientist who studies earthquakes is called a seismologist. If you're fascinated by tectonic plates, tsunamis, and everything else earthquake-related, you might want to become a seismologist. A seismologist is an expert in seismology, or the study of earthquakes. Both words are rooted in the Greek seismos, or "a shaking," and seismologists study the factors that lead to the extreme shaking caused by quakes. These scientists also investigate related events, like volcanic eruptions, connected with movements of the earth's crust and shifting tectonic plates, and predict when and where future earthquakes will occur.
