Block wall eroding at base

Hi, A block wall at our house is eroding at the base. The location is at the end of the wall where it wraps around the corner and terminates up the hill. Is there anyway to sure up the eroded section without tearing the wall down and rebuilding sections, if you can rebuild just a section. Possibly dig out some and set a form and put a concrete base in? Rains are coming soon in california, not wanting things to get worse.
thanks for any advice

Its coming apart because there is nothing under it to support the weight.

Is there any kind of footer under the rest of the wall? Appears that is needs to be take apart back to the area where it is solid, new footer installed into the hill on the left to give the tapered section support!

I don't think those types of block require a concrete footer but I do agree that wall [or section] needs to come down and be rebuilt.

Dry stack retaining walls do not use concrete footers. You should have a compacted stone base under your wall. It looks like the installers got lazy and didn't do any base/footer under that end of the wall. That end of the wall needs to be disassembled. A proper compacted crushed stone base installed and the blocks re-stacked.

engineered flexible retaining walls 1st need a compacted base of ( 'graded aggregate base course' - 'crusher run' - 'run of crush' ) in order to perform correctly - NOT concrete,,, the 1st course is installed level w/surrounding grade,,, whoever built yours didn't do it right,,, the wall's not eroding - just falling down
