"Please accept my deep condolences on the numerous human casualties and large-scale destruction caused by a powerful earthquake in your country," Putin said in his message to Erdogan on Monday.
"We are ready to provide the necessary assistance in this regard."
Separately, Putin told Assad that Russia shared "the sadness and pain of those who lost their loved ones" and said Russia was ready to provide help.
Earlier, Russia's defence ministry said its military facilities in Syria had not been damaged by the earthquake.
