The Discovery channel has a very interesting program on this specific issue. For example they've found Yellowstone has risen several centimeters from a 1920's survey.

Actually, it rose from the 1920's to the 1980's, but has now started to subside again. It was 90 cm higher than the 1920's level, now it's only 50 cm higher. (sigh of relief)
