While it is true that stampedes occur sometime because people rush in to take a look at the deity, in this particular case that is not what happened. There is no final word on what caused the stampede and the rumors are about landslides, not about people rushing to see the deity.
Also, though it is correct that people's religious zeal can sometimes be a cause for stampede, it is generally not the main cause. The main cause is the lack of proper facilities and crowd management at the temples. If even one-tenth of that 9 crores were spent properly in modernizing the temple surroundings, this incident might not have happened.
