Tokyo, Sep 30: A strong earthquake occurred in the Pacific Ocean and was felt in Guam on Sunday morning, officials and various agencies said. No injuries, damage or tsunamis were immediately reported.

The US Geological Survey reported the quake magnitude at 6.8 and said it occurred about 340 km south-southeast of the US territory of Guam. It had a depth of about 10 km beneath the sea floor, according to the USGS.

The Japan Meteorological Agency said the quake had a preliminary magnitude of 7.1 and that it occurred around 11.09 am Japan time (7.39 am IST). The agency cited information provided by the Pacific Tsunami Warning Centre in Honolulu, Hawaii.

Although the Japanese agency issued no tsunami warnings, it said there may be a chance of a tsunami near the epicentre.

However, a Hawaii centre official said it had not received any tsunami reports.

"It's very unlikely any destructive tsunami was created by this earthquake," said Stuart Weinstein, assistant director of the Hawaii centre. "It would have reached Guam by now."

"We haven't received any reports of tsunami activity in Guam, but we did hear that the earthquake was felt in Guam," Weinstein said.
