1590, (w), The Faerie Queene, III.2:

Her alablaster brest she soft did kis, / Which all that while shee felt to pant and quake, / As it an Earth-quake were: at last she thus bespake.

Last year's earthquake crushed his house, his livelihood and very nearly his leg, he said, pointing to a plastered limb that refuses to heal.

Since the response of some man-made structures to the ground motion near the epicenter is highly dependent on frequency, a significant difference in potential damage to the structures is expected between earthquakes and moonquakes.

The wave patterns, too, are strikingly different: The secondary (S) waves and surface waves on lunar seismograms are not generally as clearly defined and distinct as are those of earthquakes.
