Causes of landslide in chittagong: A heavy rainfull during a shorter period of time can lead to a large scale landslide in a hill area.

Collapse of building: Recently a five storied building toppled in to three tinshed houses on the cities begunbari area and killed 25 people.

It is also patently clear that the workmanship and engineering as well as the materials that went into the making of that house were also of very poor quality..
Obviously, the begunbari case is not the first of its kind, as we know of other instances of similar building collapse in the past at tejgaon, saver and in the older part of city .
