In response, a U.S. student has called on women around the world to dress immodestly -- show a little cleavage, or some short shorts -- to show their disapproval of Hojatoleslam Kazem Sedighi's claims.
Sedighi said in his Friday Prayers sermon last week that women who do not fully observe the obligatory Islamic hijab lead to the spread of adultery in Iranian society, which increases the risk of earthquakes.
Jennifer McCreight, a 22-year-old double major in genetics and evolution, decided to challenge him by creating the "Boobquake" group on Facebook to "help fight supernatural thinking and the oppression of women, just by dressing immodestly."
The Facebook page has attracted over 100,000 fans and it has got a lot of Western media attention.
"Boobquake" is due to take place on Monday, April 26. Watch out for earthquakes!
