A strong earthquake shook a mountainous region in western China near a famous national park on Tuesday evening, with no immediate reports of injuries or damage. The U.S. Geological Survey said the magnitude 6.5 quake struck a region bordered by the provinces of Sichuan and Gansu at a depth of just 9 kilometers (5.5 miles). Shallow earthquakes tend to cause more damage than deeper ones.

The China Earthquake Networks Center measured the quake at magnitude 7.0 and said it struck at a depth of 20 kilometers (12 miles). The quake occurred at about 9:20 p.m. near Jiuzhaigou, or Jiuzhai Valley, a national park known for spectacular waterfalls and karst formations, the Chinese agency said. CONTINUE
