MICROSEISMS Meaning and
Definition
-
Microseisms refer to very low amplitude and low-frequency seismic waves that are produced by natural or human-induced sources. These vibrations are generally imperceptible to humans without the aid of sensitive instruments. Microseisms are commonly generated by phenomena such as oceanic waves, wind, atmospheric pressure changes, and human activities like mining or construction.
Oceanic waves are one of the primary sources of microseisms, particularly due to the interaction of waves with the shoreline. The continuous breaking and movement of waves generate seismic waves that propagate through the Earth's crust. Additionally, wind interacting with landforms and vegetation can create low-frequency vibrations that contribute to microseismic activity.
Atmospheric pressure changes can also produce microseisms. Fluctuations in air pressure caused by weather systems or atmospheric disturbances generate waves that are transmitted into the solid Earth. These waves travel through the crust and are considered part of the microseismic spectrum.
Human activities such as mining and construction can induce microseisms. Activities like blasting, drilling, and heavy machinery operations generate seismic waves that propagate through the ground. These man-made sources of microseisms can be monitored and assessed to evaluate the potential impact on structures or geological features.
Overall, microseisms encompass a wide range of low amplitude and low-frequency seismic waves that arise from natural processes or human activities. Understanding and monitoring microseismic activity is crucial for various fields, including seismology, geophysics, and structural engineering.

Etymology of MICROSEISMS
The word "microseisms" is derived from the combination of two terms: "micro" and "seisms".
1. Micro: The term "micro" comes from the Greek word "mikros", meaning small or minute. It is often used as a prefix meaning one millionth (10⁻⁶) or something extremely small.
2. Seism: The term "seism" comes from the Greek word "seismos", which means shaking or quake. It is often used in the context of earthquakes or earth movements.
By combining these two terms, "microseisms" refers to small-scale vibrations or tremors that are often imperceptible or non-destructive.
