Pereira (AFP)
Colombian volunteers and rescuers cleared rubble with their bare hands and buckets to search for survivors early on Tuesday after the country's strongest earthquake in a decade killed at least 132 people and smashed dozens of buildings.
The 7.4-magnitude quake struck cities across Colombia's western region shortly after 7:30 am (1230 GMT), sending panicked residents onto the streets, AFP journalists saw.
The quake killed 132 people and injured more than 570 as of Monday afternoon, according to the Colombian Association of Capital Cities, a group coordinating major cities across the country.
Colombian President Abelardo de la Espriella - just three days after being sworn into the job - declared a state of emergency and vowed a concerted rescue effort.
De la Espriella said earlier the death toll was 111.
The city of Pereira, which was among those hit hardest, was mostly plunged into darkness amid power outages on Monday night as volunteers probed for signs of life under collapsed buildings.
There were scenes of destruction in several cities, with furniture and fabrics sandwiched between concrete, walls and floors tossed into irregular angles, and cabling strewn across roads.
In Manizales, the quake crumpled a tower of the city's beloved neo-Gothic cathedral.
In Quibdo, the capital of Colombia's Choco department, local official Jenny Rivas said public services and communications "have been virtually shut down."
Overnight searches
The quake was felt across Colombia, including the capital Bogota, where crowds rushed out into the street in their pyjamas.
At a depth of 110 kilometers, the quake was also felt in neighboring Ecuador and Panama.
Experts at the US Geological Survey said the quake was likely caused by movement along a deep fault within the Nazca tectonic plate.
Hospitals in five Colombian cities were put on red alert Monday and a nighttime curfew was declared in Cali, according to local authorities.
At least six local airports suspended operations, the civil aeronautics agency said.
Colombian pop megastar Shakira led the calls for unity.
"All my strength and love to my homeland. Let's hold each other tight," she said.
In Cali, Colombia's third-largest city, volunteers quickly went to work with picks, basic tools and their hands to try to find survivors.
Rescuers formed human chains to remove bricks and masonry, stopping every few minutes to listen for signs of life from those trapped below.
"We are trying to get everyone out alive," said Andres Felipe Mejia, another volunteer.
International support
The devastation comes less than two months after powerful twin quakes rattled neighboring Venezuela, killing over 6,300 people and leaving tens of thousands homeless.
Messages of support came in from countries across the region and the world.
Secretary of State Marco Rubio said the United States was "closely monitoring" the situation and "stands ready to support the people of Colombia."
The US later announced $15.5 million in emergency relief.
European Union chief Ursula von der Leyen said the EU had mobilized Copernicus, a satellite service, to help with rescue operations.
Mexico, Ecuador and France also offered assistance.
