SANTIAGO, Chile (AP) — A strong magnitude-6.7 earthquake shook central Chile late Monday, prompting authorities to order the evacuation of a stretch of coastline and causing hundreds of people in the capital to flee buildings in panic.

There were no reports of major damage, but authorities in the port city of Valparaiso said a 72-year-old man died of a heart attack during the quake. The earthquake was felt for almost a minute in Valparaiso and the capital, Santiago.

The U.S. Geological Survey initially put the quake’s magnitude at 6.5 but later raised it to 6.7. Its epicenter was 26 miles (42 kilometers) northeast of Valparaiso, and it had a depth of 23 miles (37 kilometers). It struck just minutes before midnight local time Monday (3:50 Tuesday GMT).

The Chilean navy’s hydrographic and oceanographic service discounted the possibility of a tsunami, but authorities maintained an order for people to move to higher ground along a roughly 500-mile (roughly 780 kms) stretch of coastline running from the city of Constitucion to Tongoy, north of the capital. Thousands of people were later allowed to return home, said Deputy Interior Secretary Rodrigo Ubilla.
