(Adds magnitude) SANTIAGO, April 22 (Reuters) - A 5.3 magnitude quake was felt in the Chilean capital, Santiago, on Sunday but there were no immediate reports of damage. The quake followed a strong temblor in the country's south on Saturday that caused power cuts, landslides and large waves off the nation's Pacific coast. The U.S. Geological Survey said the quake occurred at 6:22 a.m. local time (10:22 GMT), with its epicenter 54 miles (86 kilometers) north northeast of Chile's port city of Valparaiso, and 83 miles (134 kilometers) from Santiago. The length of Chile is prone to earthquakes.
