PADANG, Indonesia (Reuters) - A strong earthquake struck off Indonesia's Sumatra Island on Sunday, but no tsunami warning was issued, the country's meteorological agency said.
The U.S. Geological Survey measured the quake at 7.0 and said it struck near the Mentawai islands off Sumatra island at a depth of 32 km (20 miles).
The tremors toppled some telephone poles in the West Sumatra capital of Padang, but no injuries have been reported.
The epicentre was 43 km southeast of Siberut island off Sumatra's west coast, the meterological agency said in a text message.
"There are no reports of damage or injuries," Fauzi, head of the seismology centre at the agency, told Reuters. He said no tsunami alert had been issued.
"The quake was felt in Bukittinggi town, sending people rushing out of their homes," he added.
The Japan Meteorological Agency said in an email alert there was a very small possibility of a destructive local tsunami in the Indian Ocean.
The quake was followed by a 5.2 aftershock in the same area, the Indonesian meteorological agency said in a text message alert.
