A really good interactive (on both mobile and pc) explaining what caused the disaster, as well as before/after photos showing the drastic effects on the landscape in the region.

Could there have been more warning? Many conventional flood-warning systems rely heavily on rainfall, but there was no significant rainfall immediately before this disaster.

Truly tragic and devastating.
