To begin the Earthquake Quest, talk to Rhyhorn Master Rob located in Fuchsia City. Rhyhorn Master Rob knows a great move which you can learn to your Pokemon and he's willing to share his knowledge, but in order to prove your worthiness you have to complete a few tasks. Upon completing the quest, you will be given a TM26. Also, you'll then be able to purchase said TM from Earl in Celadon City for 15,000.
The first task Rhyhorn Master Rob gives you is to make your way though almost all of Kanto within 25 minutes. Along the way you're supposed to interact with five Checkpoints before you make your way back to Fuchsia City again, and you're not allowed to make use of the Keebacorp transportation systems.
- The first checkpoint is located on the north side of Cinnabar Island, on the left of the Pokémart.
- The second checkpoint can be found in Pewter City, on the left of the Pokécenter.
- The third checkpoint is in Cerulean City, next to the Pokécenter
- The fourth checkpoint is located in Lavender Town next to the Pokécenter.
- The final checkpoint can be found in Celadon City on the western edge of the city.
Beware: the race isn't over until you've talked to Rhyhorn Master Rob in Fuchsia City again.
After showing Rhyhorn Master Rob your Rhyhorn, he'll ask you to raise its happiness to 40% (102/255) , but you aren't allowed to level him up more than thrice. You'll have to do a lot of walking.
When you show Rhyhorn Master Rob how happy your newly obtained Pokemon is, he wants to challenge you. He'll give you 72 hours to beat him with a team consisting of: a) the pokemon you've shown him and b) 5 other Pokemon below level 20. You're allowed to battle him up to 5 times.

After all this Rhyhorn Master Rob finally deems you worthy of learning his powerful technique. The only thing that's left for you to do is to talk to his friend Earl in Celadon City.
Did you think that was the end of the line? I'm sorry, but it's not. When you talk to Earl, he wants to test you himself: you have to show him a team of 6 different Pokemon that all learn Earthquake naturally.
Earl will now ask you to battle him if he approves of your team.

After defeating him, he'll reward you with a TM26 and you're now able to buy more of them from him for 15,000.
