there's no evidence of faults or earthquakes on mars, hence why it's believed there to be no plate techtonics.
there are plate techtonics on the earth though. after that, i would highly dispute anything on that website. what else do you explain the continants as they are now, after spreading out from pangea? (that's what the supercontinant is called, right?)

When the site said "There is no evidence on Mars for large-scale plate tectonics as we find on Earth. " it meant there are no tectonics like we have here on Earth.
As to there being no evidence of quakes on Mars, this would be expected if the core had cooled to the point of being solid. The Volcanos aren't active on there, either, but we know they were at some point.
