Rhyhorn will learn earthquake at level 52. However, if you evolved it at level 42 into Rhydorn you will have to wait 6 levels later than normal to learn earthquake.
Here is a battle of rhyhorn and machamp. Rhyhorn uses rock blast on machamp, but machamp stops it by using hurricane punch. Rhyhorn uses horn drill, but machamp uses quick attack, causing damage on rhyhorn. Rhyhorn uses earthquake on machamp, causing damage on it. Machamp uses seismic toss, killing rhyhorn. Machamp wins.
