More on Gay Sex and Earthquakes

"We have seen the underground earthquake, tsunami, Katrina, and now Haiti. All this is in sync with a two thousand year old teaching in the Talmud that the practice of homosexuality is a spiritual cause of earthquakes. Once a disaster is unleashed, innocents are also victims just like in Chernobyl."
- Rabbi Yehuda Levin, spokesman for the Rabbinical Alliance of America

What I don't know is whether Justinian got it from Talmudic scholars or whether Rabbi Levin is claiming something as long-standing rabbinical tradition that Justinian made up in the first place.
