Question Hour: Nepal earthquake one year on

It's hard to imagine a more disastrous disaster zone than Nepal's steep and slippery slopes. It was a day when Nepal saw what it had dreamt off. An earthquake of 7.8 magnitude jolted the Himalayan country leaving over 8,000 people dead and injured more than 21,000. It was the worst natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake.
