Stampedes are a common occurrence at Hindu religious holidays, where officials find it difficult to manage the large number of devotees gathered in one place In the past, these “temple crushes,” as the local press refers to them, have been caused by railings that gave way, barricades overturned by the crush of the crowd, or panic spread by police intervention.

But there are legions of other causes. In January, more than 100 people died and 100 more were injured during a stampede near a temple in the state of Kerala in Southern India, reportedly caused by an SUV blocking the devotees’ path. In March of last year, at least 71 people were killed and more than 200 injured at a temple in Kunda in the northern state of Uttar Pradesh after the gates of the temple collapsed.

And in September 2008, 147 people were killed at a temple in Jodhpur in the northwest state of Rajasthan reportedly because of rumors a bomb had been planted in a temple complex. It later turned out that steep and slippery slopes and an inefficient response by officials had also contributed to the stampede.
