A Seismic Conundrum

"Earthquake" already sounds like a fantasy term, so do fantasy authors have to come up with a new term for it? That's before getting into fanciful causes for them. Or is it? Perhaps an earthquake caused by a catfish should have a different name from one caused to two smiths competing to create the strongest suit of armor underground. The latter would I suppose be a hoploclasm, and as for the former, "thrashwhisker." Those are bad, and therefore they fit in with "earthquake."
