 Since Vishnu relieved ("vimochana") the sin ("saabha") of Shiva (also called Hara), the temple is called Hara Saabha Vimochana Temple.After the incident, the tank came to be known as Kapala Theertham ("kapala" indicates skull).Shiva was pleased and he built the Hara Sabha Vimochana temple and also built a temple for himself near it.
