In Pereira and Cali, families slept in parks as aftershocks rattled damaged neighbourhoods where entire blocks had been reduced to rubble. The 7.4-magnitude quake injured more than 1,670 people, according to a tally by municipal authorities. It overwhelmed parts of the health system, turning the rescue effort into one of Colombia's largest disaster responses in years. The quake is Colombia's strongest in over a decade and has left hundreds still trapped under rubble. Colombian rescue workers have rallied to gather food and water supplies for those who have been displaced from the earthquake.
