seismically

Seismically is an English adverb meaning in a manner related to earthquakes or seismic activity. It is used to indicate that something pertains to or is caused by earthquakes or seismic waves, often modifying adjectives or verbs. For example, one might say that a region is seismically active or that a ground response was seismically induced.

The term derives from seismology, the scientific study of earthquakes and the propagation of seismic waves. It comes from the root seism-, from Greek seismos meaning a shaking, with the adverbial suffix -ically. The related adjective seismic describes something connected with earthquakes, such as seismic waves or seismic hazards.

In practice, seismically appears in geoscience, civil engineering, and hazard assessment writings. It helps distinguish earthquake-related phenomena from other natural processes. Common usages include seismically active fault zones, seismically induced ground motion, or seismically isolated structures. The word supports concise description of contexts where seismic activity is a defining factor.

Seismically influenced data are collected using seismographs and analyzed to understand earthquake characteristics, such as the type of seismic waves (P, S, surface waves) and the energy released. In engineering and planning, terms like seismically safe design, seismically resilient buildings, and seismically conditioned performance reflect the application of earthquake-related knowledge to construction and policy.

Note: seismic is a related adjective describing nouns (seismic activity, seismic hazard), while seismically is the adverb used to describe actions or qualities tied to earthquakes.
