More than 55,000 people were backing the official "Boobquake" page of Jennifer McCreight, a self-described "geeky, perverted atheist feminist" putting her D-cup breasts where her mouth is.
McCreight, who lives in the US state of Indiana, used the world's leading social network and microblogging service Twitter to enlist women worldwide to test the cleric's assertion that sexy women can make the ground shake.
"Many women who do not dress modestly .. lead young men astray, corrupting their chastity and spread adultery in society, which (consequently) increases earthquakes," Hojatoleslam Kazem Sedighi was quoted last week as saying by Iranian media.

What started as a barbed poke at what she saw as bad science on the cleric's part won a passionate following as it bounced around the internet, and by Monday a pair of Boobquake rallies were planned.
McCreight, a university senior majoring in genetics, chose a titillating low-cut red blouse with spaghetti string straps for the day, posting a photo of herself at her blog online at blaghag.com.
"I encourage other female sceptics to join me and embrace the supposed supernatural power of their breasts," McCreight said on the Boobquake Facebook page. "Or short shorts, if that's your preferred form of immodesty."
