The condition or occurrence of very small seismic events, often related to natural or human activities, that are not usually felt by people.
Scientists study microseismicity to understand the effects of underground mining on the surrounding area.
Microseismicity → It is formed from "micro-" (from Greek "mikros", meaning small) and "seismicity" (from Greek "seismos", meaning earthquake or shaking). The term refers to the occurrence of small-scale seismic events or vibrations in the earth.
Think of 'small' ('micro-') earthquakes or vibrations ('seismicity') to remember that microseismicity refers to minor seismic activities.
