What is another word for microseisms?
Pronunciation: [mˈa͡ɪkɹə͡ʊsˌa͡ɪzəmz] (IPA) 
Microseisms is a term used to describe faint seismic vibrations that are often caused by ocean waves and atmospheric pressure variations. Alternatives to the term could include "seismic noise," "ambient vibrations," or "earth tremors." Other terms, such as "seismic hum," "microtremors," and "low-frequency oscillations," can also be used to describe similar phenomena. Additionally, the term "infra-sound" can be used to describe sounds that are too low in frequency for humans to hear but can still cause subtle seismic vibrations. These synonyms may be useful in scientific research or in discussions about geology, seismology, or oceanography.
