TAPACHULA, Mexico (AP) — A strong earthquake shook the border of Mexico and Guatemala early Sunday, driving frightened residents into the streets.

The temblor struck just before 6 a.m. near the Mexican border town of Suchiate, where a river by the same name divides the two countries. The epicenter was just off the Pacific coast, 10 miles (16 kilometers) west-southwest of Brisas Barra de Suchiate where the river empties into the sea.

The earthquake had a preliminary magnitude of 6.4, according to the U.S. Geological Survey and a depth of 47 miles (75 kilometers).

In Mexico, there were no immediate reports of damage, but more mountainous, remote parts of the border are prone to landslides.

Across the border Guatemala’s national disaster prevention agency shared photos of small landslides onto highways in the Quetzaltenango region and large cracks in walls in a hospital in San Marcos on its social media accounts, but there were no reports of deaths.
