A moderate earthquake with a magnitude of 5.4 struck southwest China on Saturday, the United States Geological Service said.
The quake hit the border region between Sichuan province and Gansu to the northwest at a depth of about 10 kilometres, the USGS said.
The epicentre was about 50 kilometres northwest of the Sichuan city of Guangyuan, the report said.
There were no immediate reports of damage from today's quake.
The area, including Guangyuan, was rocked by a devastating magnitude 8.0 earthquake on May 12 last year that left more than 87,000 people dead or missing.
