Yes it is quarter log cabin. You make as many as you want depending on the size of the quilt. I did mine without a pattern just looked at a pic of a quilt and used scraps of a quilt I made for my husband (log cabin) and made one that is 6x6 blocks (I mean 36 blocks). You start with the four blocks in the middle to meet like you see in the pic then walk your way out by putting three quarter blocks in each of the corners of the first block and just go from there.
Here is a pic of few strips I just put so you can see the original block
