Rescue workers searching through piles of rubble after an earthquake — an all-too familiar sight.
However, sometimes it does not even take the force of an earthquake to send a building crashing down.
On Wednesday, an eight-story factory building collapsed in Bangladesh, claiming nearly 100 lives. Many remain trapped in the rubble.
Scores of people have been killed or wounded in sudden building collapses over the past decade. Often, the structures in question were illegally constructed, do not conform to building codes, or have been poorly maintained.
And it's the inhabitants who pay the price.
