How do you get the TM26 Earthquake in Pokemon Platinum?!

Question

I have gotten to the last bicycle ramp in the top right corner of the secret entrance to the cave under the bridge but even in 4th gear it wont jump two spaces to the place you need to be to get TM26.

Answer 1

If you don't like watching videos (like me) then you might find value in this guide with step-by-step screenshots on exactly where the Earthquake TM is located in Wayward Cave. It does require some tricky jumps but the main part is at the very end of the jumping path you want to turn down to go up the stairs here & avoid the ledge on the left:

Also for repeat TM copies you can get Earthquake as a Pickup item on a Pickup Pokemon between levels 91-100, which might be an easier grind than stacking BP to buy copies at the Battle Frontier.

Answer 2

It is found in Wayward Cave. To find Wayward Cave watch this video.
It can also be bought for 48 BP at the Battle Frontier. Hope you find the video easier to follow than I did.

Answer 3

You can find a very easy to follow video here. What he does for the last jump is go down and gain momentum, then turn and jump over the rock. Then he follows the path and goes up into a small room where the TM is located.

The video also shows how to reach Wayward Cave (where the TM is located), if you are having trouble with that.
