Can earthquakes be silent

Yes, earthquakes can be silent, particularly when they occur at depths of several kilometers below the Earth's surface, where they may not produce noticeable shaking at the surface. These deep earthquakes can release significant energy without causing the ground to shake violently. Additionally, slow-slip events, which are a type of seismic activity, can occur over days or weeks without any audible noise or felt shaking, often going unnoticed by people.
