Is it true that volcano locations, after they've run their course in one spot, move forward to another hit?

We posed this question to Chris Kilburn from University College London...

Chris K -   Sometimes it appears to be the case.  For example, Hawaii and other midplates of volcanic chains have evidence that the activity migrates in a particular direction with time over geological timescales.  In other volcanic areas, you don't actually see the same process.  So, it can be observed, but it doesn’t have to be.

There is a nice chain of "extinct" volcanoes sticking out of a featureless plain in northern Arizona that look as if they could have been produced by the Continent moving over a hot spot.
There ain'ta no sanity clause, and there ain'ta no centrifugal force ćther.
