(CNN) -- At least one person was killed as a 6.9-magnitude earthquake struck Monday morning in southern Mexico's Chiapas state near the border with Guatemala, authorities in Chiapas said. The quake happened at 6:23 a.m. (7:23 a.m. ET), about 1 mile from Puerto Madero, Mexico, which is on the country's Pacific coast. Strong shaking was felt in southern Chiapas state and western Guatemala, according to the U.S. Geological Survey. In the Chiapas town of Huixtla, about 30 miles (48 kilometers) to the north of the epicenter, a person died after a wall fell on him, Chiapas' state civil protection system said on Twitter on Monday.
