What is another word for micro seism?
Pronunciation: [mˈa͡ɪkɹə͡ʊ sˈa͡ɪzəm] (IPA) 
Micro seism refers to the low-amplitude ground motion that is caused by natural phenomena, such as ocean waves and atmospheric disturbances. Synonyms for this term include microtremors, ambient vibrations, and earth tremors. Microtremors are very small vibrations that are caused by natural sources and pose a significant challenge to seismic hazard assessment. Ambient vibrations are small seismic waves that are caused by various sources, such as traffic and urban environments. Earth tremors are small shocks that are caused by a sudden release of energy along a fault. Regardless of the term used, these low-level vibrations can provide important information about the subsurface structure and can help researchers better understand the seismic hazards in a particular region.
