In my opinion, yes, it is only a matter of semantics and a way for seismologists to expand the frequency domain in which they have always operated. Creep is not an earthquake. It releases strain but in an aseismic manner. It can only be measured by geodesy. This is an interesting question.
Some strain is released aseismically.
We've seen this after the Landers earthquake, too, from continuous GPS measurements. As I indicated before we will also be able to measure earthquake-induced ground motions directly. A seismometer measures ground accelerations and then doubly-integrates to compute ground motion. No, of course not. We need to distinguish between seismic and aseismic deformation.
