Iran is one of the world's most earthquake-prone countries, but the explanation for the tremors by one cleric left a lot of people scratching their heads.
Hojatoleslam Kazem Sedighi said: 'Many women who do not dress modestly... lead young men astray, corrupt their chastity and spread adultery in society, which (consequently) increases earthquakes.'
In order to prove him wrong, over 30,000 women have signed up to a Facebook group called Boobquake.
It was started by Jennifer McCreight, who wants to test the cleric's claim scientifically, by getting thousands of women to show off their cleavages to see if any tectonic movements follow.
'On Monday, April 26th, I will wear the most cleavage-showing shirt I own,' she says. 'Yes, the one usually reserved for a night on the town.
'I encourage other female skeptics to join me and embrace the supposed supernatural power of their breasts. Or short shorts, if that's your preferred form of immodesty.
'With the power of our scandalous bodies combined, we should surely produce an earthquake. If not, I'm sure Sedighi can come up with a rational explanation for why the ground didn't rumble…'
Her plea has met with resounding success, with thousands eagerly promising to flaunt their wares.
Group member Rebecca Hogan trumpeted: 'Hell yes. They will be out in force.' And Jenny Love remarked: 'My puppies will be delighted to be there.'
