What is another word for micro-seism?
Pronunciation: [mˈa͡ɪkɹə͡ʊsˈa͡ɪzəm] (IPA) 
Micro-seism is a term used to describe the small, low-intensity vibrations that are generated by natural or human-made sources. Such vibrations are often difficult to detect or measure, and as a result, scientists and researchers have developed several synonyms to describe them. One such synonym is microtremor, which refers specifically to seismic waves with frequencies below 1 Hz. Another synonym is ambient vibration, which encompasses all forms of small-scale vibrations, including those generated by human activity. Still, other synonyms include ground noise, micro-vibration, tremor, and earth hum. Each of these synonyms provides scientists and researchers with a more precise and specific terminology to describe various forms of micro-seismic activity.
