A family captured video of the moment they fled their home during an earthquake in Colombia. Liliana Pérez Ocampo and her family escaped moments before their home was rocked by a 7.4 magnitude quake on Monday. Her family, including two young children at school, are safe. "In the end, material things can be replaced," she said. With at least 169 people killed, this has been the strongest earthquake to hit Colombia in the 21st Century, according to the country's Geological Service.
