The quake hit at 2:29 p.m. local time (1929 GMT). Its epicenter was 115 km from the capital Guatemala City.

Benedicto Giron, spokesman for the National Disaster Reduction Center, said there had been some landslides in the southwest province of Escuintla but they apparently didn't cause any serious problems.

He noted that telephone service was down in some areas and information was tricking in slowly from the various provinces.

"It rattled a lot of nerves," said Giron.

The Geological Survey said the temblor was strong enough and close enough to population areas to have caused damage.

The quake was felt strongly in neighboring El Salvador, where some people ran into the streets in the capital of San Salvador, but the Red Cross there said it had no reports of damage or injury. It was also felt in the Mexican city of Tapachula, near the Guatemalan border.

The Pacific Tsunami Warning Center based in Hawaii said no tsunami was expected from the quake.

The region is prone to earthquakes. Almost 23,000 people died in a 1976 earthquake.
