A 5.3-magnitude earthquake struck Hunchun city in northeast China\'s Jilin Province just before dawn Wednesday, causing no injuries or damage, local authorities said. The quake hit the city at 4:17 a.m.. Its epicenter at a depth of 539 kilometers, was at 43.3 degrees north latitude and 130.9 degrees east longitude, Xinhua quoted the China Earthquake Networks Center as saying. Most people in the city slept through the quake. An official from the earthquake bureau in Yanbian Korean Autonomous Prefecture said the quake was deep-focused and would not be felt or cause damage. Huichun is on the only deep-focus earthquake belt on China\'s mainland. Quakes in this region generally have a focus depth of more than 500 km. Only earthquakes occurring at a depth of less than 70 km are considered \"shallow\". --SPA
