The crater was created by a cavitation bubble which projects a plasma jet that penetrates the surface od the metal to excavate a pit into the metal as seen in the picture you reference..
Yes, the mechanism of cavitation is different from SPP in Ni/H because the SPP is produced on the walls of the collapsing cavitation bubble exterior to the metal and projected onto the nearest surface of metal that is adjacent to the bubble.
