Topic: Chocó earthquake

A magnitude 7.4 earthquake struck Colombia's Pacific coast early Monday morning, killing at least 22 people and sending tremors across the country and into neighboring Ecuador and Panama. The United States Geological Survey measured the quake at 7.4. Colombia's Servicio Geológico Colombiano initially put the figure lower, between 6.6 and 6.7, before subsequent assessments moved closer to the USGS reading. The gap between those early numbers reflects how difficult it is to pin down a major seismic event in real time.
