What does seismically mean?
“Seismically” is an adverb meaning in relation to earthquakes or movement of the Earth's crust. It is often used with words such as “active,” “stable,” or “unstable” to describe the degree or character of seismic activity in a region. The word can also be used figuratively to mean to a very great extent, as in “seismically important,” indicating that something has brought about profound change. In these figurative contexts, the word draws a comparison between major societal or organizational transformation and the powerful forces associated with earthquakes. Its usage is formal and somewhat emphatic, so it is especially common in scientific writing, journalism, and discussions of major political, cultural, or economic shifts. It is not ordinarily used for minor changes or ordinary increases, where words such as “slightly” or “moderately” would be more appropriate.

Etymology of seismically
“Seismically” was formed in English by adding the adverbial suffix “-ally” to “seismic.” “Seismic” comes from Greek seismos, meaning “earthquake,” which is related to the Greek verb seisō, “to shake.” The same Greek root also lies behind words such as “seismology,” “seismograph,” and “seismologist.”
