Earthquake

Definition of earthquake:

part of speech: noun

A shaking or heaving of the ground.

part of speech: noun

A shaking, trembling, or concussion of the earth: sometimes a slight tremor: at other times a violent shaking or convulsion: at other times a rocking or heaving of the earth. The earthquake shock generally comes on with a deep rumbling noise, or with a tremendous explosion resembling the discharge of artillery, or the bursting of a thunder- cloud; the ground is raised vertically at the centre of the disturbed tract, but the movement is more oblique the farther we proceed from that centre; and the rate of increase of obliquity furnishes material for calculating the depth of the shock below the surface.

part of speech: noun

A shaking or trembling of the ground produced by explosions or slidings beneath the surface.
