= Microseism
{wiki=Microseism}
Microseism refers to a type of very low-frequency seismic activity that is typically caused by natural phenomena, such as ocean waves, earthquakes, and other geological processes. These seismic vibrations occur at frequencies usually between 0.1 Hz and 0.5 Hz and are often too weak to be felt by humans but can be detected using sensitive seismic instruments. Microseisms are primarily generated by the interaction of ocean waves with the seafloor, particularly in regions with significant wave activity.
