Casting my mind back to Plate tectonics classes 20 years ago, energy release to achieve equilibration is what earthquakes are all about. The audible bang is only one of the several ways in which an earthquake releases energy. The others are heat and movement. If the sound did indeed precede the shake, it'd prove that the energy released travels faster through the air (in the form of sound waves) than through the crust (as motion waves). I forget which is which.
As the North Island sits right atop two plates which are trying to go in opposite directions it is never going to be a stable place to live. I recall my lecturer in 1977 predicting that the North Island would cease to exist within a century - apparently the two plates have been stuck together for way too long to be healthy.
As regards your question - hows about "backslide". (Must admit I didn't have to think too much about that one - thanks for the leg up!! Will think further on the matter no that the geology lesson has been delivered.

As one who has lived in that bowl of jello called Mexico City, I know what you mean about the jiggles. I was never there during anything strong, but I can imagine it as being unsettling. My sympathies. How about motorhome?

Soundbite, waterfall, powercut are just 3 examples in which, like in your two, the second part can be read as a noun as well as a verb. Stretching the point only a little further, cornerstone, woodfire and cardhouse would also qualify.

Per Stales' and Consuelo's comments, the entire Pacific is known as The Ring of Fire to geologists and vulcanologists, since it seems that the volcanoes that one finds on both sides of the Pacific (now THERE'S a misnomer!) indicate where the fractures in the plates are. We here in Oregon had a shake of equivalent magnitude (but no magma-tude!) last year, and, of course there was Mt Saint Helens in 1980. I heard quite a bang from that, and I then lived over 200 Km away.
As for noun/verbs, probate is a bit of a stretch, but it's too early here to think.

Dear Stales: Can you tell us how it is possible for the forces that drive the plates to have such a constant effect over so many years?
