Unless you live on another planet, you've certainly heard of the earthquake that happened in Nepal that has claimed the lives of thousands and cost unimaginable destruction.
Many people have never seen what an earthquake looks like.
Take a look at this clip from a CCTV camera in Kathmandu. Note that this is just an aftershock of the earthquake, not the real earthquake that happens at the epicentre.
Our hearts and prayers are with the people of Nepal.
