Rescue workers and volunteers scrambled to clear debris as they searched for survivors in Colombia early Tuesday after the country was hit by the strongest earthquake on record. As of Monday afternoon, at least 132 people had been killed and more than 570 injured, according to the Colombian Association of Capital Cities, a group that coordinates major cities across the country. As of Monday night, more than 2,700 people had been reported missing. Many families posted information about their loved ones online, hoping to gain insight into their fate. The 7.4 magnitude earthquake struck cities in the western region of Colombia shortly after 7:30 a.m. local time, sending terrified residents into the streets.

Honestly, this looks like a zombie city,” resident Juan David Gaitán told the French news agency AFP. At Pereira airport, videos showed pieces of roof falling on sheltering and screaming travelers, and people running through the rubble in panic. The country’s president, Abelardo de la Espriella, who had been in office only three days, declared a state of emergency and promised a concerted rescue effort.

The farmer lived in a rural area of Cairo, not far from the epicenter of the earthquake in San José del Palmar. “We are afraid. We hope that it is not like that, that he is fine and that it is just a communication failure. But we have not heard anything from him,” Zamora said. De la Espriella announced Monday night that he had mobilized “the entire military and police apparatus” to respond to the tremor.

The first is rescue and recovery,” Fabio Andrade, Weston city commissioner and a Colombian-American, told CBS News Miami. More from CBS News Go deeper with The Free Press in:
