earth tremors
Seismic ground movement
Earth tremors are minor vibrations or shakings of the ground, typically caused by seismic activity that falls short of a full earthquake.
They may result from shifting tectonic plates, volcanic activity, or even human activities like mining or construction.
Residents reported feeling earth tremors throughout the night.
While often barely perceptible, earth tremors can serve as precursors to larger seismic events, prompting monitoring by geologists.
