Fairly extensive wrap-up, although body not found:

I had buffering problems with this link. May have been on this end.
Woman who escaped was buried up to her shoulders or waist, dog was apparently clear of the collapse.
Again stated they were at the bottom of the cliff.
High-tide pix show ocean waves right up to the site of collapse. (No wonder they were thinking she may have been washed out to sea.)
Name of victim not released to save family from exposure to media.
Officials will not change signage (sample shown in video) or anything else, citing that this kind of thing is very rare, and it is a matter of common sense.
Before-and-after pics of the collapsed area shown.

PS. Scouting around on gravity versus dirt, I found this clip of a big earth collapse at Niagara Falls in the 1950s:
